Boston Red Sox closer Aroldis Chapman thinks he'll be able to pitch in a couple of days after walking off the mound with a back spasm in the eighth inning of Sunday's game against the Los Angeles Dodgers. In to face the top of the Dodgers' order, his velocity was noticeably down to mid-90 mph on his fastball instead of the high 90s to low 100s. Manager Alex Cora and a trainer came out to the mound to visit him after Shohei Ohtani flew out to the left-field warning track.
