The Dodgers recalled Klein from Triple-A Oklahoma City on Friday.

Klein owns a 3.38 ERA through 10.2 innings with the Dodgers this season but hasn't enjoyed the same success in Triple-A, where he carries a 6.23 ERA and 1.75 WHIP through 43.1 frames. Despite his performance in the minors, the Dodgers will bring him back onto the big-league roster to replace Michael Kopech (knee) in the bullpen. Klein will likely be limited to low-leverage situations.

The Dodgers placed Kopech on the 15-day injured list Friday with right knee inflammation.

Renewed inflammation in Kopech's knee will force him back onto the injured list, putting an early end to what was an injury-filled 2025 campaign. Manager Dave Roberts said Friday that the Dodgers will aim to "reset" the 29-year-old while he's on the IL, per Jack Harris of the Los Angeles Times, and the team is optimistic that he'll return sometime during the postseason. In the meantime, Will Klein will come up from Triple-A Oklahoma City to fill the open spot in Los Angeles' bullpen.

Kopech is tending to uncertain physical issues which are expected to require a stint on the injured list, Bill Plunkett of The Orange County Register reports.

Kopech didn't say what was bothering him specifically, but he's expected to need some time off to recover. The 29-year-old has endured some control issues recently, having walked eight batters in his last four appearances spanning 2.2 innings. Will Klein is expected to be added to the active roster as the corresponding move.

The Marlins reinstated Tarnok (ankle) from the 15-day injured list Friday and optioned him to Triple-A Jacksonville.

Tarnok has been on the shelf since early September due to a sprained left ankle, but he's been cleared to return after a brief rehab stint. The 26-year-old will head to Jacksonville for the closing week or so of the regular season. He has a 3.19 ERA in 67.2 innings with Jacksonville in 2025.

Atlanta optioned Dunning to Triple-A Gwinnett on Friday.

Dunning has struggled in a mop-up role with Atlanta, posting a 10.80 ERA over seven appearances. His spot on the roster and in the bullpen will be absorbed by Jhancarlos Lara.

Faucher earned the save Thursday against the Rockies, recording the final out of the game while allowing one hit.

The right-hander was summoned with two outs in the ninth inning after Valente Bellozo surrendered four runs to put the game in peril. Faucher gave up a single to Hunter Goodman before inducing a game-ending groundout to secure the victory. Faucher has been sharp of late, holding opponents scoreless in seven of his last eight appearances, and he needed just six pitches to wrap things up Thursday. On the season, the 29-year-old has converted 14 of 19 save chances while adding seven holds with a 3.28 ERA, 1.23 WHIP and 56:22 K:BB across 57.2 innings.

Vesia struck out two in a perfect inning to earn the save in Thursday's 2-1 win over the Giants.

Vesia and Tanner Scott were the only relievers the Dodgers used Wednesday, but Vesia's workload was lighter in that appearance. That put him in position to get a save opportunity Thursday, and the southpaw delivered a sharp outing to convert it. Since returning from an oblique injury Sept. 9, Vesia has allowed one run over 4.2 innings, adding two holds and a 7:1 K:BB in that span. He's at a 2.68 ERA, 0.95 WHIP and 76:19 K:BB through 57 innings this season. Vesia has converted five saves while adding 23 holds and four blown saves as a fixture in the high-leverage mix throughout the year.

Koenig allowed a hit and struck out one over a scoreless inning to earn the save in Thursday's 5-2 win over the Angels.

Abner Uribe was deployed against the heart of the Angels' order in the eighth inning, leaving Koenig to pick up the save in the ninth. This was Koenig's seventh straight scoreless outing, and he's posted a 14:1 K:BB while earning two saves and a hold in that span. He's pitched well as a high-leverage option this year, posting a 3.10 ERA, 1.23 WHIP and 64:20 K:BB with two saves and 26 holds over 61 innings.

Atlanta transferred Bummer (shoulder) to the 60-day injured list Thursday.

Left shoulder inflammation sent Bummer to the injured list in late August, and although he began a throwing program Saturday, his move to the 60-day IL will officially rule him out for the rest of the season. He'll give up his place on the 40-man roster to Brett Wisely, who was claimed off waivers from San Francisco in a corresponding move.

The Diamondbacks optioned Backhus to Triple-A Reno on Thursday.

Backhus has appeared in 32 games out of Arizona's bullpen this season, recording a 4.62 ERA, 1.42 WHIP and 22:8 K:BB across 25.1 innings. He picked up his second save of the season in last Sunday's win over the Twins.
