Lackey is on the disabled list, but hopes to miss only a couple of starts.
MassLive.com’s Evan Drellich is reporting via Twitter that the Red Sox placed Lackey on the disabled list and called up Alex Wilson from Pawtucket to take his place on the roster:
Stephen Drew's activation is official and John Lackey is on the 15-day disabled list. Alex Wilson, on the 40-man roster, has been called up.— Evan Drellich (@EvanDrellich) April 10, 2013
That start was Lackey's first since 2011 after Tommy John surgery kept him out of all of 2012.
He had struck out eight batters in 4.1 innings against Toronto, before having to leave the game while clutching his arm.
According to Paul Casella of MLB.com, an MRI showed no structural damage but the team decided to put Lackey on the disabled list as a precaution.
Lackey, who is hoping to only miss a couple of starts, told WEEI’s Rob Bradford that he was both frustrated and relieved by the news. “It could have been a lot worse, for sure. I’m definitely frustrated a little bit but relieved, too. It could have been worse.”
ESPNBoston wrote that the transaction was made retroactive to April 7, meaning Lackey will be eligible to return as soon as April 22.
According to the Providence Journal’s Brian MacPherson and Tim Britton, right-handed reliever Alfredo Aceves, who replaced Lackey after he was hurt, is expected to take his spot in the rotation.
Aceves has given up five earned runs in just 4.1 innings this year, and has made only a total of nine starts in his six-year major league career. But the 30-year-old made three starts during spring training and is sufficiently stretched out to assume the role on a temporary basis. This will also allow the Red Sox to not throw prized pitching prospects Allen Webster and Rubby De La Rosa into a stressful situation this early in the season.
Replacing Lackey on the roster is 26-year-old right-handed reliever Alex Wilson, who will be getting his first taste of major league experience.
A former second-round draft choice of the Red Sox, Wilson began his career as a starter but converted to relief last year. He has a career minor league record of 22-14 with a 3.81 ERA in 107 games.
SoxProspects.com describes Wilson’s arsenal as including a low-90s fastball, above average slider and a developing changeup.
In other news, the Red Sox activated shortstop Stephen Drew from the disabled list and sent Jose Iglesias to Triple-A Pawtucket. Drew will assume the starting role while Iglesias will get more experience in the minor leagues.
