Keith (back) is not in the lineup for Friday's game against Atlanta.

Keith had to be lifted from Thursday's contest versus the Guardians with a back injury and was sent for an MRI, so it's no surprise he's not ready to play in Friday's series opener. There's no word yet on the results of the imaging, but the Tigers should have an update on the 24-year-old soon. Zach McKinstry will play third base and bat eighth in Keith's stead.

Rooker went 1-for-4 with a two-run home run in Thursday's 5-3 win over Boston.

That makes it three long balls in Rooker's past five games, and Thursday's blast gave him his third consecutive 30-homer campaign. The slugging outfielder has been an excellent four-category fantasy contributor in 2025, hitting .267 with 87 RBI and 91 runs scored to go with a career-high 40 doubles over 599 at-bats. Rooker has benefitted significantly from seeing around half of his action at hitter-friendly Sutter Health Park -- he has an .891 OPS at home versus a .779 OPS on the road.

Keith will undergo medical imaging after exiting Thursday's game against the Guardians with a back injury, Evan Woodbery of MLive.com reports.

Keith was lifted after grabbing at the side of his back at the end of the second inning. Tigers manager A.J. Hinch described the injury as "very concerning," suggesting it's possible Keith strained something and could miss an extended amount of time. More will be known about Keith's status after the MRI results are in, which should be Friday.

Keith was removed from Thursday's game against the Guardians due to an apparent back injury, Evan Petzold of the Detroit Free Press reports.

Keith was spotted grabbing at his lower back at the end of the second inning before heading into the clubhouse alongside one of the Tigers' trainers. The severity of his injury isn't immediately clear, but the team should provide an update in the near future.

Devers went 1-for-5 with an RBI in Wednesday's 5-1 extra-innings win over the Diamondbacks.

Devers singled in the 11th inning, driving in the Giants' final run. The 28-year-old has reached base safely in back-to-back outings after having been held hitless in his previous three. Over 15 games this month, he's slashing .190/.299/.362 with 12 runs scored, 10 RBI, three home runs and a 28.4 percent strikeout rate across 67 plate appearances.

Santander (shoulder) is likely to remain on his rehab assignment with Triple-A Buffalo through the weekend, Arden Zwelling of Sportsnet.ca reports.

Santander has played six rehab games with Buffalo so far and saw his first action in the outfield Wednesday, though he didn't have a single ball hit to him over seven innings in left field. The 30-year-old will be Buffalo's designated hitter Thursday. Santander -- who is 4-for-22 with one homer so far on his rehab assignment -- has been sidelined since late May with a subluxation of his left shoulder. He'll aim to rejoin the Blue Jays' active roster for the final week of the regular season.

Diaz went 2-for-2 with an RBI and two walks Wednesday against the Blue Jays.

Diaz continued his excellent September by tallying his third consecutive multi-hit game. Across 15 games in the month, Diaz has hit .429 with a .515 on-base percentage while tallying two homers, seven RBI and 11 runs scored. He's also had an excellent season overall, posting career-high marks in home runs (24) and RBI (81).

Yoshida went 2-for-4 with two RBI in Wednesday's 5-4 extra-inning win over the Athletics.

Yoshida, who entered the game with a .618 OPS through 44 games, batted cleanup and delivered a run-scoring single in the first inning. He later hustled out an infield single with the bases loaded to plate a run in the fifth. His season numbers are underwhelming, but Yoshida is making a modest impact in September. He's gone 10-for-32 (.313) with two doubles and six RBI over 10 games this month.

Ballesteros went 1-for-3 with a solo home run in Wednesday's 8-4 win over the Pirates.

Ballesteros has settled in as Chicago's primary designated hitter recently, having started the last six games, and he's responding well at the plate. The 21-year-old rookie has gone 8-for-21 across those six contests with a triple, two home runs, three RBI and five runs scored. With Kyle Tucker (calf) on the injured list, the Cubs have used more of Willi Castro and Seiya Suzuki in right field, which has opened the door at DH for Ballesteros. He should maintain elevated fantasy value this season for however long Tucker remains out, and the youngster's long-term outlook remains promising.

McCutchen went 1-for-4 with a walk, an RBI and a run scored Wednesday against the Cubs.

McCutchen was involved in a pair of Pirates rallies, scoring on a Joey Bart home run after singling in the first frame and then walking in a run one inning later. He's had mixed results in September, hitting only .175 across 40 at-bats, though he's also delivered six RBI and six runs scored across 11 games.
