Worth noting

• While Red Sox general manager Ben Cherington said on Wednesday that he wouldn't rule out Xander Bogaerts returning to shortstop sometime this season, Farrell said Thursday that it would take plenty of factors before that would be considered.

"We don't want to move Xander back and forth. We want some stability defensively," Farrell said. "Until that combination of players changes, we'll stay as is."

Jackie Bradley Jr. has saved the fourth-most defensive runs of any outfielder in baseball, according to fangraphs.com. The statistics and Bradley's play on the field show the rookie is a difference-maker in center, and despite inconsistency at the plate, Farrell is happy with where Bradley is --- even if he isn't necessarily being recognized league-wide yet.

"Sometimes the Gold Glove awards aren't defensive, solely. I think there's some bias when you factor in the offensive production. That's kind of just history, as it shows," Farrell said. "He's playing at a level defensively that you can stack up against anyone in the game. It's great to see his confidence play out on the defensive side of things."

On Wednesday night, Bradley made likely his finest catch of the year and one of the best of the Major League season when he laid out at full extension to snag a line drive in the right-center field gap. He immediately broke left after the ball was hit and needed to be nearly perfect to make the play.

David Ross and Christian Vazquez will alternate starts behind the plate until the All-Star break, Farrell said. Vazquez made his Major League debut Wednesday when the club designated A.J. Pierzynski for assignment, and Ross was in the lineup Thursday, catching Jon Lester. Vazquez is expected to start Friday in Houston.

Farrell said he's not exactly sure how the playing time for Vazquez and Ross will be split following the break.

"We fully expect or anticipate a playing split, the times per week to be three for Ross and four for Vazquez as a little bit of a guide," said Farrell.
