BOSTON - Rubby De La Rosa will make his first major league start for the Red Sox on Saturday night, taking the spot of Clay Buchholz on the roster and facing the Tampa Bay Rays at Fenway Park.
"There are four pitches available to him,'' said John Farrell. "Strike-throwing has continued to be maintained and above-average and there's been times when the velocity has really climbed to the upper 90s. So he's pitching with some confidence right now.''
Reports have De La Rosa, 25, throwing his breaking ball with more definitionand also showing an improved changeup.
"There's been more aggressiveness and assertiveness on the mound,'' said Farrell.
De La Rosa, acquired in the trade that sent Adrian Gonzalez, Carl Crawford and Josh Beckett to the Dodgers in 2012, has pitched in 25 major league games - 14 for the Dodgers, 11 for the Red Sox- and gone 4-7 with a 4.21 ERA.
