OKC • Center-Forward • #55
1 day ago
After averaging a double-double for the first time in his NBA career last season, Hartenstein is on his way to doing it again in 2025-26. He’s recorded at least 13 rebounds in five games and is responsible for six double-doubles. Hartenstein is ranked well within the top-50 in nine-cat formats, and his skill set is such that maintaining that production level is a realistic possibility. The Thunder play three games during Week 4, starting with the Warriors on Tuesday.

A big 15-point second quarter led the veteran center to a 20-point, 10-rebound double-double at halftime, which eventually turned into a career-best night for Hartenstein. He missed only three shots en route to his first game of more than 20 points this season, while nearly snagging 20 boards in the process. In his second year with the Thunder, Hartenstein continues to make a massive impact for one of the league’s best teams. He’ll have a chance to land a third straight double-double on Sunday against the Grizzlies.

Hartenstein nearly recorded his first-ever triple-double on Sunday, but a lopsided Thunder win limited him to just 26 minutes of game action. In his time on the floor, he impressed in all phases of the game and helped OKC remain unbeaten on the season. The veteran center has scored in double figures in four of the first seven games of the season while reaching double-digits in rebounds in five of the first seven games. He’s picked up where he left things last season, which was a career-best for him.

The Thunder were without Chet Holmgren for a second consecutive game on Thursday. After attempting just three shots in Tuesday’s win over the Kings, Hartenstein was more active on the offensive end of the floor against the Wizards, scoring a season-high 17 points. Despite his low free-throw percentage (54.5), Harteinstein isn’t too far outside the top-100 in nine-cat formats. He remains a must-roster player, especially in leagues that have two-center lineups.

Hartenstein had more of a scoring role in this one as the Thunder were without Chet Holmgren. The 27-year-old center led the team in shot attempts with 10 and had 13 points in 22 minutes. He didn’t attempt a free throw. Hartenstein didn’t have his usual playmaking role against the Bucks as he had just one assist despite averaging a career-high 3.8 assists with the Thunder last year. He’s going in the middle rounds of 2025 fantasy basketball drafts.

After starting Cason Wallace in the first three games of the NBA Finals, Thunder coach Mark Daigneault has gone back to his usual first five. Hartenstein returns to the lineup, with Wallace heading to the bench. Hartenstein can be a capable facilitator in the short roll, and his floater in those spots is close to automatic. After playing 33 minutes in Game 1, Wallace logged 24 and 23 minutes in Games 2 and 3.

Hartenstein was solid as a scorer and rebounder, but Monday’s game was another instance in which the Thunder decided to go small in crunch time. Hartenstein was an observer from the bench, while Oklahoma City decided to use Chet Holmgren (12/6/2/1/4) as the center with Alex Caruso entering the lineup. Holmgren had a chance to extend Oklahoma City’s lead to three with 9.5 seconds remaining, but his two misses were followed by Aaron Gordon’s game-winning three. Hartenstein’s playing time will be fine, but the way he’s used in this series will be worth watching, especially when Nikola Jokic is as dominant as he was in Game 1. The Thunder host Game 2 on Wednesday.

Hartenstein and Holmgren’s continued absences mean Kenrich Williams and Jaylin Williams should remain in the starting lineup for Sunday’s regular-season finale. The latter only needed 25 minutes to record a triple-double in Friday’s win over the Jazz; keep an eye on JayWill for Sunday as well, since that’s another good matchup for him. Kenrich will have value in active deep leagues.

A sore left hip hastened Hartenstein’s exit from Saturday’s game, with Kenrich Williams replacing him in the lineup to begin the third quarter. With Chet Holmgren and Jaylin Williams also out, Kenny Hustle and Branden Carlson will play additional minutes during the second half od Saturday’s contest.

Hartenstein has had at least 10 rebounds in six-straight games and has recorded a double-double in five of those games, including Thursday night against the Grizzlies. The 26-year-old center’s 18 points came on just nine field goal attempts as he was able to get to the foul line eight times and make all of his free throws. Hartenstein’s high scoring game overlapped with Chet Holmgren struggling with just four points of his own. Hartenstein even managed to play more minutes than Holmgren. While we can’t expect that to happen regularly, fantasy managers will take it. Hartenstein has still managed to provide good fantasy value since Holmgren returned to action after missing the beginning of the season.

After joining multiple rotation players in sitting out Wednesday’s game against Philadelphia, Hartenstein was back in the lineup on Friday. He only played 25 minutes in the blowout win, but that was enough time for him to record a double-double. OKC has already locked up the best record in the West, so it’s certainly possible that Hartenstein and the rest of the rotation pieces see more rest nights and minutes limits for the rest of the regular season, which would limit their fantasy output.

Hartenstein will be back after missing Wednesday’s game against Philadelphia. Jaylin Williams started and recorded a triple-double in that game, but he will likely be pushed back to a reserve role with Hartenstein back in the rotation.

The Thunder are already without Shai Gilgeous-Alexander, Luguentz Dort and Jalen Williams, and they won’t have Hartenstein or Wallace for Wednesday’s game, either. Aaron Wiggins and Chet Holmgren are among those who are available, which raises their fantasy ceilings. The only question is how much they’ll play since they are key members of Oklahoma City’s regular rotation.

Hartenstein was sensational on Sunday, recording his first 20-point double-double of the season. The Thunder center has provided eighth-round value in eight- and nine-cat formats since the All-Star break, which hasn’t been far off his season-long production. While injuries have limited the time Hartenstein and Chet Holmgren have been on the court together, the partnership has worked smoothly thus far. With Oklahoma City playing three games without a back-to-back during Week 20, availability should not be an issue for Hartenstein or Holmgren.

Hartenstein has been consistently productive for the Thunder this season, which is unsurprising given how well he played with the Knicks last season. And since the All-Star break, the OKC center has been an eighth-round player in eight- and nine-cat formats. While Hartenstein’s season-long value is higher, fantasy managers don’t have much to complain about this season.

Oklahoma City had both of its starting big men available for Monday’s game, the team’s second in as many days. However, neither Hartenstein nor Chet Holmgren (8/4/1/0/2) played more than 30 minutes in the rematch with the Nuggets. Given how far ahead of the competition the Thunder are in the Western Conference, it would be unsurprising if the team took steps to rest some of its key players ahead of the postseason. As long as Hartenstein and Holmgren are on the court, fantasy managers will receive solid value from both on most nights.

Both big men sat out Friday, and Jaylin Williams got the starting nod at center. Williams posted a triple-double in 36 minutes, but his workload should be significantly reduced on Sunday with Hartenstein and Holmgren back in the lineup.

Hartenstein apparently re-aggravated his nasal injury, while Wallace will miss his first game since before the All-Star break. They’ll join Shai Gilgeous-Alexander and Jalen Williams among other Thunder starters, paving the way for role players like Alex Caruso, Jaylin Williams, Isaiah Joe and Aaron Wiggins to see extra run.

With Chet Holmgren out of the lineup, Hartenstein stepped up on both ends of the floor Wednesday night. Over the past week, he’s recorded double-doubles in three of his last four games, providing fourth-round value in eight- and nine-cat formats. Due to Holmgren’s injuries this season, there will likely be more nights when Hartenstein is the lone big in the starting lineup. As he’s shown throughout the season, iHart has reliable fantasy value regardless of who is (or isn’t) on the court.

The Thunder are without Chet Holmgren, who sprained his ankle during Friday’s win over the Hawks. Hartenstein returns to the starting lineup after coming off the bench in Atlanta, and the promotion raises his fantasy ceiling.
