David Peterson got just four outs and gave up five runs Tuesday in his start against the Cubs.

Peterson surrendered two runs in the first on a single, a walk and a fly to right that Juan Soto turned into a double. The second started with a walk and three hits that surrounded a sac bunt, and the Mets pulled him at that point. He probably would have gotten a chance to recover if this didn’t make for five subpar outings in a row, but the team has obviously lost some faith in him. He’s not nearly so far gone that he should be ruled out going forward, but it’ll be fascinating to see the Mets’ pitching decisions from here on in. While Peterson is due to start Sunday against the Marlins, it’s anyone’s guess whether that will happen.

David Peterson allowed six hits and six runs with three walks and one strikeout over five innings in a loss to the Padres on Wednesday.

Peterson’s disastrous second half continued here. He allowed runs in each of the first two innings, but seemed to settle in reasonably well afterwards. That is, until a mammoth grand slam from Manny Machado in the fifth inning on a 3-2 curveball that caught far too much of the plate. It turned Peterson’s line from palatable to awful and the circumstances by which he got there were even more frustrating. He hit Jake Cronenworth with two strikes, walked Fernando Tatis Jr. after getting ahead of him 1-2, and then Luis Arraez dropped down a bunt single to set the stage for Machado. Peterson now has an ugly 4.86 ER since August 1st and is scheduled for a tough meeting with the Cubs up next.

David Peterson pitched decently in a no-decision against the Phillies on Thursday night, giving up three runs on seven hits across his five frames.

On the plus side for fantasy managers, Peterson racked up eight strikeouts on the night while issuing only one base on balls. After being staked to an early 4-0 lead, Peterson kept the Phillies’ offense at bay until Otto Kemp’s two-run blast in the fourth inning. They added another on an RBI double by Bryce Harper in the fifth inning. The 30-year-old southpaw got a whopping 19 swings and misses on 86 pitches in the ballgame — 10 of them on his curveball — while posting a strong CSW of 35 percent. He’ll attempt to get back in the win column as he totes a 3.77 ERA, 1.32 WHIP and a 148/60 K/BB ratio (162 1/3 innings) into Thursday’s tilt against the Padres.

David Peterson allowed seven hits and four runs with one walk and four strikeouts over 5 1/3 innings in a win against the Reds on Friday.

Peterson cruised through the first two innings as his lineup built up a big lead. Yet, he ran into trouble in both the third and fourth as the Reds put four runs on the board. Then it felt like he got over the hump and was ready to pitch deeply into this game when he began the sixth inning with just 70 pitches. Somehow, it took him 21 pitches to face three batters and he only retired one before being pulled. He didn’t have good feel for any of his pitches really as too many sinkers bled over the heart of the plate and got hammered while his breaking balls were often noncompetitive. This was his fourth clunker in his last six starts which has brought a 2.83 ERA up to a 3.72 ERA. He’ll have a stiff test next week as the Mets head to Philadelphia to take on the Phillies.

David Peterson allowed eight runs with one strikeout over two innings in a no-decision against the Marlins on Saturday.

Peterson struggled out of the gate against the Marlins, giving up five runs on five hits and a walk to open the game in the first inning. After a clean second inning two walks and three hits brought another pair of runs in to score before Peterson was relieved with no outs and the bases loaded. The 29-year-old left-hander will look for better results when he takes a 3.55 ERA, 1.31 WHIP, and a 136/58 K/BB ratio across 152 innings into a start against the Reds in Cincinnati next Saturday.

David Peterson yielded two runs in 5 2/3 innings and struck out eight Sunday versus the Braves.

Peterson had a shutout going until the sixth, when he gave up a two-run single to Sean Murphy after carelessly walking Nacho Alvarez Jr. That ended his day at 98 pitches. He had 20 whiffs, 10 of them coming on the 22 sliders he threw, and not one of his 40 breaking balls produced a hard-hit ball. This would have been a gem if he didn’t lose the strike zone at the end. He’ll face the Marlins next.

David Peterson pitched eight innings of one-run ball and struck out 10 in the Mets’ 8-1 win over the Nationals on Tuesday.

Peterson allowed just four hits in a big rebound outing after giving up six runs to the Braves last time out and four runs to the Guardians before that. It’s his first 10-strikeout game of the year. He’s had exactly one of those every season since making his major league debut in 2020. He figures to face the Braves again on Sunday.

David Peterson allowed five hits and six runs with five walks and five strikeouts over 3 1/3 innings in an ugly loss to the Braves on Wednesday.

Spotted a six-run lead, Peterson could not escape a fourth inning that spun out of control after he walked the eighth and ninth batters in the Braves’ order. He missed to his arm side all game long and was visibly frustrated on the mound as he let the Mets’ big lead evaporate, a trend that’s become all too normal lately. He’s scheduled to make a two-start week next with road games against the Nationals and Braves again.

Although he struck out seven, David Peterson gave up four runs over six innings Wednesday in a loss to the Guardians.

Peterson had allowed two runs or fewer in five straight starts. He generated 15 missed swings and had a 33% CSW today, but he gave up homers to David Fry and Angel Martínez. They were just the eighth and ninth homers he’s allowed in 133 innings this season. He’d given up just two previously in 11 starts at Citi Field. Peterson will face the Braves next week.

Although he struck out seven, David Peterson gave up four runs over six innings Wednesday in a loss to the

David Peterson allowed four hits and two runs with two walks and four strikeouts over six innings in a no-decision against the Giants on Friday.

Peterson seemed to get stronger as this game went along. The Giants scratched across two runs in the second inning and then only put three more runners on base over Peterson’s final four innings. It was his fifth consecutive start working at least six innings and his 14th time doing so this season as he’s grown into a bonafide workhorse for the Mets. He’ll take a 2.83 ERA into his next start against the Guardians at home.

David Peterson allowed just a run over six innings to get a win over the Giants on Saturday.

Peterson had to work around a lot of traffic to limit the Giants to just the lone run, as he gave up eight hits and also issues three free passes. Still, he kept San Francisco completely off the board outside of a fielder’s choice in the fourth inning off that bat of Jung Hoo Lee. Peterson now has an ERA of 2.83 and a record of 7-4, with a K/BB of 101/41 for good measure. He gets the Giants again next weekend.

David Peterson allowed one run (none earned) in six innings and got a no-decision in the Mets’ 3-2 victory over the Reds on Sunday.

Peterson gave up four hits, walked one and struck out four. The 29-year-old left-hander continues to enjoy a breakout season. Peterson lowered his ERA to 2.90 on the year with another exceptional outing. He has a 97/38 K/BB ratio in 115 innings this year. Peterson is lined up to face the Giants on the road next weekend.

David Peterson has been added to the National League roster for next week’s MLB All-Star Game.

He’s taking the place of Giants’ left-hander Robbie Ray who will start in the Giants’ first-half finale on Sunday and wouldn’t be available to pitch in the All-Staar Game. Peterson is definitely worthy of the honor — registering a 3.06 ERA, 1.23 WHIP and an 93/37 K/BB ratio across 109 innings in 18 starts for the Mets in the first half. It’s the first All-Star selection for the 29-year-old southpaw.

David Peterson was outstanding over seven innings of one-run baseball in the first game of a doubleheader against the Orioles, but he didn’t factor into the decision Thursday.

Peterson deserved better. He blanked the Orioles over his first seven frames, but he allowed a runner to reach in the eighth, and Gunnar Henderson hit a pinch-hit homer off Ryne Stanek to prevent him — and the Mets — from getting a win. Peterson allowed just five hits in the contest without issuing a walk, and he struck out six. He’ll take an excellent 3.06 ERA into the All-Star break, and he’ll likely start one of the first games after that mini vacation.

David Peterson limited the Brewers to two runs — one earned — over 6 2/3 innings in the Mets’ 3-2 victory Thursday.

Peterson, who was coming off consecutive losses in which he gave up five runs apiece, got the win tonight, moving him to 6-4 with a 3.18 ERA. Peterson is an excellent groundball pitcher, but this is the fourth straight outing in which he’s walked three batters and struck out no more than five. He had a 71/25 K/BB ratio over 79 2/3 innings in his first 13 starts. In his last four, he has a 16/12 K/BB and a 5.64 ERA in 22 1/3 innings. He’ll face the Orioles next week.

David Peterson allowed seven hits and five runs with three walks and five strikeouts over 4 2/3 innings in a loss to the Pirates on Friday.

The Pirates were all over Peterson in this one. He got through the first inning unscathed, but they sent nine men to the plate in the second and scored four runs. Of the eight balls they put in play, seven were hit harder than 100 mph and almost none were hit on the ground. In fact, Peterson was a bit lucky to leave that inning with only the four runs allowed. He couldn’t locate any of his pitches and looked much more like the Peterson we saw early in his career rather than the one who’s had an ERA under three over the last calendar year. His next start is scheduled to come at home against the red-hot Brewers.

David Peterson struggled in Sunday night’s loss to the Phillies, giving up five runs on six hits over his four innings of work.

Peterson struck out four batters on the evening while issuing three free passes. The 29-year-old southpaw kept the Phillies’ offense off the scoreboard through his first three innings of work, but they broke through with five runs in the fourth inning including a solo blast by Kyle Schwarber and a three-run homer by Edmundo Sosa. Peterson got eight whiffs on 72 pitches on the evening, registering a CSW of 25 percent. Even with this rough outing, Peterson still sports a terrific 2.98 ERA, 1.24 WHIP and a 78/31 K/BB ratio across 90 2/3 innings through his first 15 starts on the season. He’ll look to get back on track when he squares off against the Pirates in Pittsburgh on Friday.

David Peterson pitched seven-plus innings of three-run ball Tuesday in a no-decision against the Braves.

The final two runs came after he left the game in the eighth. Peterson struck out just three, but he kept the ball on the ground throughout and was rewarded with a couple of double plays. It would be his seventh straight quality start if only he’d been allowed to get one more out against the Rockies on May 30. Alas, he didn’t factor into the decision tonight after Reed Garrett blew the lead in the eighth. Peterson is due to take on the Phillies on Sunday.

David Peterson went the distance with six strikeouts and scattered six hits without walking a batter in a 5-0 win over the Nationals on Wednesday.

What a moment for Peterson. He was met by a roaring ovation from the Citi Field faithful on his way to the mound just before finishing off the first complete game shutout of his career. An incredibly rare feat in this day and age, Peterson was very efficient on his way to this gem. He’d thrown just 32 pitches after the first three innings and forced 18 total ground balls on 25 balls in play. This was also the third time in four starts he’s completed at least seven innings and he now has a sterling 2.49 ERA, which is the fourth-lowest in the National League. He’s heading into a huge two-start week against both the Braves and Phillies on the road with some serious momentum.

David Peterson allowed three runs on seven hits in seven innings in a no-decision against the Dodgers on Thursday.

Peterson seemed to be cruising to a win before this Mets bullpen allowed three runs in the eighth inning to cough up the game. The left-hander struck out six on the day while walking two and posting a 29 percent whiff rate and 30 percent CSW. He got plenty of whiffs on his slider, and the four-seamer controlled the zone for much of the day. Peterson has been great this year, with a 2.80 ERA so far. He’s in a good spot against the Nationals next week.

David Peterson allowed five hits, one run, and one walk with five strikeouts over 5 2/3 innings in a win over the Rockies on Friday.

While Peterson wasn’t his sharpest, he still managed to work his way to a solid final line. Falling one out short of the quality start is frustrating, but the Rockies were rallying against him in the sixth innings and he was fortunate that Huascar Brazobán stranded runners on second and third base. Francisco Lindor also made a tremendous leaping grab with the bases loaded and two outs in the third to save two runs. He just didn’t quite have the usual strong command of his slider against right-handed batters which limited his swings-and-misses. He’ll have to be sharper in his next scheduled start against the Dodgers.

David Peterson hurled 7 2/3 innings of two-run baseball to get a win Saturday over the Dodgers.

Peterson allowed a pair of runs in the second inning, but from that point on the 29-year-old was outstanding against the quality Los Angeles lineup. He struck out seven against just two walks, and he held the Dodgers a 1-for-5 average when there were runners in scoring position. Peterson how has a strong ERA of 2.79 on the season, and he has yet to allow more than three runs in an outing. He’ll try and keep that streak going against the lowly Rockies next weekend.

David Peterson allowed four runs with six strikeouts over six innings in a loss to the Diamondbacks on Tuesday.

Peterson worked through three scoreless innings before the Diamondbacks brought in two runs in the fourth on a walk and two doubles. Lourdes Gurriel later took Peterson deep for a two-run homer in the sixth. He’d be done after six frames at 104 pitches, striking out six batters while issuing four walks. The 29-year-old left-hander will take a 3.52 ERA, 1.38 WHIP, and a 36/13 K/BB ratio across 38 1/3 innings into a start against the Pirates in New York on Monday.

David Peterson allowed seven hits and three earned runs with nine strikeouts over 5 1/3 innings in a no-decision against the Cardinals on Friday.

Peterson pitched much better than his line would indicate, and his line was still pretty good. The Cardinals benefited from some well placed bloops, ground balls, and wild pitch to scratch across their first two runs. Then, after the Mets rallied to tie this game up in the bottom of the fifth inning, Peterson came back out with 86 pitches as the top of the Cardinals lineup had turned over for the third time and coughed up the lead. Still, this was a fine start all things considered. Peterson drastically increased the usage of his four-seam fastball and the Cardinals seemed surprised by it with four swings-and-misses and 10 called strikes. His slider was nasty as well, especially against right-handed batters. This was also consecutive starts by Peterson without allowing a walk after he dished out eight free passes through his first two starts. He seems to be elevating his game and will be tested in a matchup against the Phillies next time out.

David Peterson allowed two runs with five strikeouts over six innings in a loss against the Athletics on Saturday.

Peterson got off to a good start, facing the minimun before the Athletics brought two runs in to score in the fourth on four hits. He tossed two more scoreless frames, ending his day with a quality start while striking out five with no walks. The 29-year-old left-hander will take a 2.70 ERA, 1.38 WHIP, and a 17/8 K/BB ratio across 16 2/3 innings into a start against the Cardinals in New York on Thursday.
