Campbell, 23, experienced both impressive highs (American League Rookie of the Month in April) and some serious lows (demoted to Triple-A Worcester in June) during his rookie campaign — with defensive struggles and some ill-timed rib discomfort unfortunately serving as the turning point.

Red Sox chief baseball officer Craig Breslow can’t keep anyone from getting injured, but believes he can do something to help the sophomore return to the level that once had him in the lineup every day.

“If you think about where his athleticism may play in the short-term, I think in the outfield, he feels pretty comfortable as a chance to just let the instincts take over,” Breslow told members of the media at MLB’s GM Meetings on Tuesday.

“I think the offseason, to have both a mental and physical reset, has been really valuable for him.”

Campbell’s bat dipped with the injury, though the reason he was demoted came as a result of persistent defensive struggles — where he accounted for seven errors at second base and slipped on the outfield depth chart behind the likes of Roman Anthony and Wilyer Abreu.

Boston is expected to have some openings in the outfield this season, however, as many believe one or two will be moved as a way to obtain the club’s two biggest needs — frontline starting pitching and a middle-of-the-order bat. Campbell, feeling like the player he was last offseason, could benefit as a result.

“He looks big and strong and is back to the size and frame he was last year,” Breslow said, as transcribed by The Boston Globe’s Tim Healey. “He’s swinging the bat fast again.”

Campbell is ultimately responsible for returning to form, but receiving support from the organization should help his chances.
