Martín Pérez allows four runs in loss Monday

As expected, Santillan will require surgery to address a labral tear in his left hip. There’s a chance that his rehabilitation process stretches into next spring. There should be a definitive return timetable following the procedure.

It seemed implausible that Lagrange, who faced hitters in a live batting practice session on Wednesday, would factor into New York’s playoff pitching plans after suffering a shoulder injury back in July. The hard-throwing 23-year-old top prospect has yet to ascend to the majors, but it’s possible he could debut as a reliever in the postseason. His triple-digit velocity would make him a certifiable weapon out of the bullpen, if the Yankees decide to go that route. He’s a fascinating talent that fantasy managers should be paying attention to heading into next year.

Steer has been on the shelf with a wrist sprain since late July. There should be a definitive return timetable following next week’s surgical procedure. The hope is that he’ll be ready for spring training after a full offseason of rest and rehabilitation.

Peters returns to center field and will hit seventh following a three-game absence after a full-speed collision with the center-field wall that left him with a shoulder contusion last Friday. The 26-year-old breakout sensation was fortunate to avoid serious injury and only miss a couple games. The White Sox find themselves one game behind the Guardians for the AL Central division crown and are close to wrapping up the final AL Wild Card playoff spot, if they don’t surpass Cleveland.

Despite making some real progress against southpaws this season, Cruz will take a seat against Cardinals lefty Matthew Liberatore in this matchup. The 27-year-old is up to 20 homers and 28 steals in just 410 plate appearances this season. He would’ve been a legitimate 30-homer, 40-steal threat had a hand injury not cost him more than two months of the year.

Bellinger gets a rare break after launching a two-run homer during Tuesday’s loss to the Rays. It’ll be José Caballero taking over in left field with Tampa Bay rolling out a bullpen game.

Eaton winds up losing his spot on Boston’s bench with center fielder Ceddanne Rafaela back from the injured list. He figures to be in the mix for one of the final spots on the club’s postseason roster given his defensive versatility.

Atlanta manager Walt Weiss told reporters Acuña is available off the bench, if needed, but they want to give him an extra day to recover after fouling a ball off his left shin during Tuesday’s game. It’ll be Brewer Hicklen taking over in right field in his place on Wednesday evening. The positive news here is that X-rays and a CT scan came back negative for any fractures and he should be ready for the outset of the postseason.

Gordon threw five innings of relief on Tuesday, so he was unlikely to be available for the rest of the regular season. He’s now eligible to be recalled on October 3rd, which will make him an option for the NL Division Series.

Richardson was designated for assignment in the middle of August but ultimately re-signed with the Brewers. He has a 6.48 ERA, 1.68 WHIP, and a 47/40 K/BB ratio over 58 1/3 innings in 42 career appearances at the MLB level.
