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 Dodgers.

Red Sox reliever Aroldis Chapman has fans worrying with velocity dipping below 94 mph before his exit on Sunday.

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.

A trade idea involving Red Sox outfielder Jarren Duran includes a return package of Guardians pitchers Shane Bieber and Emmanuel Clase.

Regarded by many as one of the finest closers in baseball, Aroldis Chapman spent one season with the Chicago Cubs in 2016.
