Worth noting

• For all the talk about Grady Sizemore's comeback attempt, Jackie Bradley Jr. looks focused on making a strong push to be the starting center fielder. In Sunday's game, he lofted a double off the Green Monster and laced a single up the middle.

"I thought he picked his spots," manager John Farrell said. "Against left-handers, he looked first-pitch fastball. When he stays in the middle of the field like we saw last spring … there's an understanding of the strike zone. He got himself in a couple of hitter's counts today, and he's going to get regular ABs to get his timing down."

• Edward Mujica made his debut with the Red Sox on Sunday, firing a scoreless inning. He looks healthy again after losing his job as the Cardinals' closer late last season.

"He's going to throw the ball over the plate, he's a strike thrower, he's been fine," Farrell said. "He's responded well. Given what he went through last year, we've cut his bullpens to every third day. He's responded favorably to that. He's right on track.

• The Red Sox signed Bo Greenwell, the son of former left fielder Mike Greenwell, to a Minor League contract. Bo Greenwell was selected by the Indians in sixth round of the 2007 First-Year Player Draft. The 25-year-old lives in Fort Myers and is a.278 hitter over 1,962 career at-bats in the Minors.
