Right-hander Brad Peacock was optioned to the minors Tuesday, and Graham Godfrey will start in his place in Wednesday’s exhibition against Kansas City. No big surprise here. Peacock has a 12.86 ERA in three appearances (two starts). That’s a small body of work, but bottom line is he didn’t turn heads like he needed to break camp with the team. As is the case with Jarrod Parker, manager Bob Melvin said Peacock will remain in contention for the fifth starter’s spot even as he works in the minors. The A’s don’t need a fifth starter until April 17.
