Santander (back) was removed from the Blue Jays' ALCS roster due to injury Thursday.

Santander was originally scratched from the lineup for Game 2 of the ALCS, though he managed to start in Game 3. The back issue has apparently persisted, with Joey Loperfido now taking Santander's place on the roster. If the Blue Jays advance to the World Series, Santander will be ineligible to play.

The Blue Jays plan to remove Santander (back) from their ALCS roster, Mitch Bannon of The Athletic reports.

Santander was scratched from the lineup ahead of Game 2 due to lower-back tightness, and renewed soreness will keep him from playing in Game 4 on Thursday as well. The Blue Jays are still in the process of determining the severity of the outfielder's injury, but the expectation is that he will be replaced on the postseason roster. His removal would also render him ineligible to play in the World Series, should Toronto advance, effectively ending his season.

Gausman will start against the Mariners in Game 5 of the ALCS on Friday, Ben Nicholson-Smith of Sportsnet.ca reports.

Gausman was able to record 17 outs in Game 1 before allowing Seattle to score a run and ended up given up two runs over 5.2 innings. Now sporting a 2.38 ERA through 11.1 frames in the postseason, he'll potentially be tasked with ensuring the series returns to Toronto.

Santander isn't in the lineup for Game 4 of the ALCS against the Mariners on Thursday.

Santander rejoined the starting nine Wednesday after sitting out Game 2 due to lower-back tightness, but he'll now return to the bench Thursday after experiencing renewed stiffness in his back, per Ben Nicholson-Smith of Sportsnet.ca. Addison Barger will move to the outfield as a result, putting Ernie Clement at the hot corner and Isiah Kiner-Falefa at second base.

Woo will be available out of the bullpen Friday in Game 5 of the ALCS versus the Blue Jays, Tim Booth of The Seattle Times reports.

Woo had been a candidate to start Game 5, but the Mariners will instead turn to Bryce Miller for their final home game of the series. The 25-year-old Woo has not appeared in a game since Sept. 19 due to right pectoral inflammation, but he's healthy now and will give Seattle some length in relief, if needed.

Miller will start Friday's Game 5 of the ALCS against the Blue Jays, Tim Booth of The Seattle Times reports.

The Mariners will turn to Miller again after he tossed six innings of one-run ball on short rest in Game 1. He will be taking the ball on regular rest Friday and will have Bryan Woo available out of the bullpen behind him to provide length, if needed. The Blue Jays are expected to counter with Kevin Gausman as their Game 5 starter.

Robles isn't in the lineup Thursday for Game 4 of the ALCS against the Blue Jays.

Robles has gone just 3-for-26 (.115) in the postseason so far, so the Mariners will keep him on the bench Thursday. Dominic Canzone will take over in right field, moving Jorge Polanco into the DH spot and opening up second base for Leo Rivas.

Quintana is likely to pitch in Game 4 of the NLCS versus the Dodgers on Friday, Curt Hogg of the Milwaukee Journal Sentinel reports.

Quintana had been a candidate to see work in Game 3, but the Brewers will go with Aaron Ashby as the opener and Jacob Misiorowski as the bulk reliever Thursday. It's unclear whether Quintana will make a traditional start or serve in a bulk relief role Friday, but in either case he'll likely soak up most of the innings for Milwaukee in Game 4. The veteran southpaw tossed three scoreless innings out of the bullpen in NLDS Game 3 against the Cubs in his lone appearance this postseason.

Misiorowski is expected to follow opener Aaron Ashby as a bulk reliever in Thursday's NLCS Game 3 against the Dodgers, Curt Hogg of the Milwaukee Journal Sentinel reports.

Misiorowski has yet to pitch in the NLCS after tossing seven innings of one-run ball with a 7:2 K:BB across two NLDS appearances versus the Cubs. He will be on four days' rest after throwing 54 pitches over four frames in NLDS Game 5, so the hard-throwing right-hander should be prepared to provide plenty of length.

Bauers will start in left field and bat eighth in Thursday's NLCS Game 3 versus the Dodgers.

Bauers drew the start in left field in Game 2 and went 0-for-3 at the dish, but he'll get another opportunity in Game 3 as the series moves to Los Angeles. The 30-year-old Bauers was one of the Brewers' best hitters down the stretch of the regular season, slashing .360/.458/.560 with a pair of home runs in September. He's gone 3-for-8 with one home run, one double and a 1:1 BB:K in four games this postseason.
