"This was outlined after Stephen came back," said manager John Farrell. "We targeted today as part of that progression and he'll be back in the lineup [Wednesday]. This is about getting Stephen back to nine innings every day."
Jonathan Herrera made the start at shortstop while Xander Bogaerts was at third base for the second straight game.
Eventually, Bogaerts could find himself at short against lefties. For now, Farrell wants to give Bogaerts the chance to get reacclimated at third.
Grady Sizemore was out of the lineup against the lefty, with Alex Hassan starting in right two days after he got a hit in his Major League debut.
