Chapman had tried to convince manager Alex Cora to let him stay in the game in order to face Teoscar Hernández with runners on first and second and one out. But Cora refused, pulling Chapman and summoning righthander Jordan Hicks.

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.

Boston Red Sox reliever Aroldis Chapman left the team's 4-3 win over the Los Angeles Dodgers on Sunday with back tightness, according to Chris Cotillo of MassLive.com.
