OAKLAND -- Roster flexibility is in tow with the flip of the calendar on Saturday, as the A's called up infielder Brandon Hicks and outfielder Collin Cowgill.
The additions of Brandon Inge and starter A.J. Griffin, reinstated from the disabled list on the same day, brought the A's roster to 29 as they continue their unrelenting push toward the postseason.
Hicks, who hit three home runs in 20 games during his first stint with the A's, was immediately inserted into the lineup for the second of a three-game set with the Red Sox, starting at shortstop while manager Bob Melvin gave Stephen Drew a scheduled day off. Cowgill, meanwhile, provides the club speed off the bench, as well as the ability to get on base.
In his two previous stints with the A's, Cowgill hit .271 with a .343 on-base percentage, one home run and nine RBIs spanning 32 games.
"He's a versatile guy for us," Melvin said. "You always like to have a guy that can run, an aggressive guy that can pinch-run and spell Coco [Crisp] if he needs a day off and is a good defender at all three of the [outfield] positions.
"I'm not sure as far as starts go for him, but he'll give us some in-game depth that we didn't have and, with rosters expanding, you look for some variables, some facets that you maybe don't normally have with just 25 guys."
Speed is one of Jemile Weeks' biggest assets, yet the second baseman -- optioned Aug. 21 in a shocker of a move -- wasn't among the additions on Saturday, and it doesn't appear he'll be one any time soon, based on a vague response Melvin issued to reporters.
"I think anything's still possible," he said. "I don't know. I don't know what to tell you on that one at this point."
Weeks, who was hitting just .220 with the A's, has rallied for a .417 average with Triple-A Sacramento, where he also has a .488 on-base percentage and nine RBIs in eight games. But even without him, the A's still have a handful of options at second base, with Cliff Pennington and Adam Rosales having split time there in Weeks' absence.
