He homered Tuesday night in a 6-4, 14-inning loss to Baltimore.

Last season, the 27-year-old Giambi hit .283 in 124 games, while collecting 12 homers and 57 RBIs.

He also finished second in 2001 among American League pinch-hitters with a .250 batting average with six runs batted in.

For his career, Giambi has a .272 batting average with 35 homers and 166 RBIs in three-plus years.

In 21 games this season, Mabry is batting .286 with no homers and three RBIs.

In a pinch-hitting role, the 31-year-old was hitting .313 with a pair of runs batted in.

Mabry is a .271 career hitter in seven-plus seasons.

The trade between the Phils and the A's is the first since 1973, when Deron Johnson went to Oakland for minor league catcher Jack Bastable.
