Beginning Sept. 1, major league rosters can expand from 25 all the way to 40. The Phils, however, have added one additional player since the beginning of the month, reliever Jack Taschner.

Today, they'll add another.

Triple-A catcher Paul Hoover will join the major league team today. Hoover hit .253 in 73 games with the IronPigs, where he shared most of the time behind the plate with since-traded catching prospect Lou Marson.

Hoover, 33, last appeared in the major leagues in 2008. He hit .200 in 13 games with the Marlins last season.

The Phils will have to make a corresponding roster move to get Hoover onto the 40-man roster. In addition, they'll also have to find another spot for Brett Myers, who appears ready to join the team, too.

Hoover gives the Phils depth at the catcher position, with Carlos Ruiz and Paul Bako, for the season's final month of play.
