Rivas will start at second base and bat ninth in Friday's ALCS Game 5 versus the Blue Jays.

For the second straight game, the Mariners are going with Rivas at second base, Jorge Polanco in the designated hitter spot and Dominic Canzone in right field, with Victor Robles retreating to the bench. Rivas went 0-for-2 with a walk in Thursday's Game 4 loss.

Tigers president of baseball operations Scott Harris and manager A.J. Hinch said at their end-of-season press conference Monday that Melton will be a starting pitcher next season, Evan Petzold of the Detroit Free Press reports.

Melton bounced between the rotation and bullpen for the Tigers in 2025 both in the regular season and playoffs and was impressive in both roles, collecting a 2.76 ERA, 1.01 WHIP and 36:15 K:BB over 45.2 regular-season frames. The 24-year-old has been almost exclusively a starting pitcher in the minors and held a 2.99 ERA and 101:20 K:BB across 75.1 innings between Double-A Erie and Triple-A Toledo this season.

Yankees manager Aaron Boone said Thursday that he views Rice as the team's primary first baseman next season, Gary Phillips of the New York Daily News reports.

Rice split time between designated hitter (48 starts), first base (46 starts) and catcher (26 starts) in 2025, slashing .255/.337/.499 with 26 home runs across 530 regular-season plate appearances. Boone didn't rule out Rice serving as the team's No. 2 or No. 3 catcher in 2026, but most of the 26-year-old's playing time is expected to come at first base.

Castillo (1-1) allowed three earned runs on five hits and one walk while striking out one across 2.1 innings to take the loss in Game 4 of the ALCS on Thursday.

Castillo got through two innings unscathed, but he allowed five of the first six hitters he faced in the third frame to reach base before being pulled. This was Castillo's first stumble of the postseason, as he had previously thrown six scoreless innings across two appearances in the ALDS. He has a less impressive 5:5 K:BB, but he has largely been a reliable arm for Seattle.

Gimenez went 2-for-3 with a two-run home run and four RBI in Game 4 of the ALCS on Thursday against the Mariners.

Gimenez delivered a pair of big hits, kicking off the scoring with a two-run home run in the third inning. He came through with a two-RBI single five frames later, and he has now driven in six runs in his last two games. Gimenez has posted a .310/.355/.552 OPS across 32 plate appearances this postseason.

Guerrero went 2-for-5 with a solo home run in Game 4 of the ALCS on Thursday against the Mariners.

Guerrero provided an insurance run for the Blue Jays in the seventh inning with his fifth postseason home run. He's been a key to Toronto's success in the ALCS, going 6-for-9 with two homers, two doubles and four runs scored in his last two games.

Scherzer (1-0) allowed two earned runs on three hits and four walks while striking out five across 5.2 innings to earn the win in Game 4 of the ALCS on Thursday against the Mariners.

Scherzer drew his first start of the postseason and took the mound in a game for the first time since Sept. 24. He understandably showed some rust, issuing two free passes in the first inning and giving up a leadoff homer in the second inning. He settled in from there, allowing only a pair of singles and walks across his final 3.2 frames of work. It's unclear when Scherzer will be called upon next, but he played a big part in the Blue Jays leveling the ALCS through four games.

Loperfido was added to the Blue Jays' ACLS roster Thursday.

Loperfido will take the place of Anthony Santander (back) on the active roster. Loperfido has yet to appear in a playoff game this season, and he's likely to serve primarily as a bench bat or defensive replacement.

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.
