Lucas Giolito isn’t a ‘morning person,’ but his excellent start against the Houston Astros on Sunday prompted Red Sox manager Alex Cora to give him a funny new nickname.

Trevor Story and Ceddanne Rafaela had consecutive RBI singles in a six-run fourth inning filled with five Houston mistakes, Lucas Giolito pitched a season-high eight stellar innings, and the Boston Red Sox beat the Astros 6-1 to complete a series sweep.

Lucas Giolito’s longest outing in four years propelled the Red Sox to a 6-1, sweep-completing win over Astros on Sunday afternoon. He stifled Houston’s lineup for eight innings, allowing one run and three hits. The lone blemish: a home run from Carlos Correa on a 92-mile-per-hour fastball left over the middle of the middle of the plate.
