Alfredo Aceves a likely fill-in starter for Red Sox

TORONTO — One could understand why Red Sox manager John Farrell looked squeamish when he saw John Lackey clutch his right arm in the fifth inning of Saturday’s 5-0 loss to the Blue Jays. Over a period of four days last season while managing the Blue Jays Farrell lost three starting pitchers, derailing the team’s chances for good.

The initial news on Lackey’s injury, which was termed a biceps strain, was positive after the game, as the cramping had subsided and the strength tests were registering close to normal. Lackey will have an MRI Sunday in Boston.
