When trying to decide between Travis Buck and Todd Walker, the A's decided to keep both. Instead, the A's released Antonio Perez.
The A's wouldn't bring Buck up to the roster to be a backup, so this means he's probably the everyday right fielder. Todd Walker and Bobby Kielty will likely share a platoon as the first backup in the 1B/OF rotation. Walker also becomes the third-stringer at 2B and 3B.
I'm a bit surprised the A's couldn't find a trade partner to take Perez off their hands--several teams were rumored to be looking for backup infielders. But I suppose it's hard to find landing spots for players this late in spring training. Perhaps Perez will end up in Sacramento if he can't find a new major league home.
