Oakland employs several platoons at the moment, notably at second base and catcher, and with the Astros throwing out three right-handers against the A's this weekend, manager Bob Melvin is faced with a tough task.
Melvin started the right-handed-hitting Derek Norris behind the plate on Saturday, after platoon partner John Jaso started the first game, but Eric Sogard remained at second base for a third straight game, with the right-handed Sizemore remaining on the bench.
"It's a little more difficult when you don't have too many left-handers, so we'll certainly sprinkle Derek in there against some right-handers to keep him current," Melvin said. "Once we get to Anaheim, we get two out of three [left-handed pitchers]. You try not to let them go too long without getting them in there, but like any semi-platoon, when you have two guys to split the job, that's part of the task."
Sizemore will pick up at least two starts against the Angels, it seems, with left-handers C.J. Wilson and Jason Vargas scheduled to start Tuesday and Thursday, respectively. Former A's hurler Joe Blanton, a righty, will go Wednesday.
