BOSTON -- Diego Castillo made his "opener" debut on Sunday, holding the Red Sox scoreless on one hit in 1 2/3 innings.
Kevin Cash told reporters prior to the game that Castillo had been used in said capacity while at Triple-A Durham, so the role wasn't foreign to the right-hander. The Rays' manager said he felt like using Castillo as the opener would put Castillo in a spot to succeed.
"I look at Diego Castillo, hopefully turning into that role where he's eventually coming [into the games] in seventh-, eighth- and ninth-inning situations," Cash said.
