Just when it felt like the Diamondbacks were finding their footing, a weekend in Miami sent them tumbling. A brutal 6-4 loss on Sunday, sealed by an eighth-inning meltdown, completed a three-game sweep at the hands of the Marlins. The loss, their fourth straight, pushed the D-backs below .500 to 41-42 and led a frustrated manager Torey Lovullo to label the performance one thing: 'unacceptable.'
This was unacceptable. We're a better baseball team than this.
For much of Sunday, it looked like Arizona might salvage a game. Starter Eduardo Rodríguez was sharp, allowing just one run over 5 1/3 innings, in an effort that was ultimately wasted. But the wheels came off spectacularly in the eighth. The bullpen, which has been a source of strength, crumbled under pressure. A barrage of walks set the table for the Marlins' rally, with Otto Lopez delivering the go-ahead two-run single and Kyle Stowers breaking the game open with a three-run double. A promising start turned into another gut-wrenching defeat.
At the center of the late-game collapse was Jalen Beeks. The usually reliable reliever had a day to forget, getting tagged for five earned runs on two hits and four crucial walks without recording an out. It was a shocking turn for a pitcher who entered the weekend with a sterling 2.92 ERA and 1.00 WHIP. This single outing was a stark reminder of how quickly fortunes can change in the bullpen and a major reason the D-backs are heading home with nothing to show for their trip to Miami.
Dropping below .500 at this stage of the season is a tough pill to swallow. After a promising stretch, this four-game losing streak feels like a significant step backward. The frustration is palpable, from the manager's office to the fanbase. There's no time to dwell, however, as a crucial series against the San Francisco Giants looms. The D-backs will send Ryne Nelson to the mound to face Giants ace Logan Webb in a matchup that suddenly feels like a must-win to stop the bleeding.
This weekend was a disaster, plain and simple. The sweep exposed issues with command and timely hitting that need to be fixed immediately. The upcoming series against the Giants is no longer just another set of games; it's a gut-check. It's a chance for the Diamondbacks to prove that the team we saw in Miami was an aberration and that the fight for the NL West is far from over. It's time to turn the page, and it needs to happen now.
