Jemile Weeks went 2-for-3 with a double and a steal Thursday in his first start since being called up from Triple-A. The A's have mostly used Cliff Pennington at second base lately and they've been winning, so they probably won't be quick to make a change. Weeks, however, does offer more offensive potential at the position. The A's should give him a few more starts before they decide who they want to play at second base in the postseason, if they advance.
