Athletics' Mark Canha: Starting in center field Tuesday

Canha, who's projected to primarily serve in a right-field platoon with Matt Joyce this season, will start in center field Tuesday against the Mariners, Joe Stiglich of CSN Bay Area reports.

Analysis:

Manager Bob Melvin is trying to determine whether Canha can demonstrate enough competence in center to allow the A's to potentially keep four outfielders and an extra reliever heading into the regular season. The 28-year-old has already been deployed in center field on a couple of occasions this spring but hasn't seen much action come his way yet. He'll get another opportunity Tuesday and has been making up for the lack of chances thus far by taking extra flyballs during pregame workouts. "I've said all along the biggest difference is throws, different angles and longer throws in general," Canha said. "But I think the biggest thing for me is just remember, be an athlete out there, be aggressive."
