The reigning AL MVP jammed his left shoulder diving for a ball in Thursday’s 8-6 loss in the series opener. He served as the DH on Friday as the Angels ended a four-game losing streak with a 7-6 victory in 12 innings.
“This is something you always want to monitor the next day,” Angels manager Mike Scioscia said. “We don’t need him reaching up to make running catches right now.”
With Guerrero not part of the outfield, Scioscia inserted struggling Steve Finley in the lineup on Friday. Finley was hitless in four at-bats and is batting .216 this season—the lowest average of his 17-year career.
The Angels moved back into sole possession of first place in the AL West with Friday’s win, one game ahead of Oakland. Kelvim Escobar pitched three scoreless innings for his first win in relief this season.
Guerrero scored the winning run on pinch-hitter Robb Quinlan’s bases-loaded single in the bottom of the 12th. Guerrero went 3-for-6 and is batting .346 (18-for-32) over his last 15 games.
Rookie Ervin Santana enters Saturday’s start for Los Angeles off a pair of rough outings. Santana is 0-2 with a 9.64 ERA in his last two starts after being reached for four runs and eight hits over 5 1-3 innings in an 8-1 loss at Seattle on Monday.
“I make good pitches and they hit it,” Santana said. “I’m mad because I lost, but that is the game.”
The 22-year-old right-hander, who has never faced the Tigers, is 7-3 with a 3.30 ERA in 12 starts at home.
Detroit will also send a rookie to the mound in Roman Colon, who will make his third start of the season for the Tigers. Colon was acquired from Atlanta on July 31.
The 26-year-old right-hander, who has never faced the Angels, scattered nine hits and yielded one run over five innings in a 2-1 loss to Minnesota on Monday.
