OAKLAND -- Whether the Cardinals advance to the National League Championship Series on Friday night could potentially dictate how soon the A's fill their hitting coach vacancy.

That's because A's manager Bob Melvin is expected to try to reel in St. Louis assistant hitting coach and friend Mike Aldrete as soon as the Cardinals are eliminated from the playoffs.

Melvin and Aldrete played three seasons together with the Giants, and Aldrete -- like newly named A's bench coach Chip Hale -- is a California native. He served as Melvin's first-base coach in Seattle in 2004 and also as his hitting coach in Arizona during the 2005 and 2006 seasons.

Aldrete would fill the role previously held by Gerald Perry, who was one of three coaches for whom the A's decided not to renew contracts at season's end.

The club is also thought to be targeting Bryan Price as its new pitching coach, following the surprise dismissal of Ron Romanick. Price, who has one year left on his contract as pitching coach for the Reds, served in the same role under Melvin in Seattle and Arizona.

There is no timeline on when the A's will fill these positions.
