Reliever Antonio Bastardo was placed on the 15-day disabled list Thursday with inflammation of the ulnar nerve in his left elbow. The Phillies recalled righthander Scott Mathieson from triple-A Lehigh Valley to replace Bastardo in the bullpen.

Bastardo, who has a 5.11 ERA and nine walks in 16 appearances, last pitched Tuesday night against the New York Yankees when he walked one batter and hit two others in two-thirds of an inning.

Mathieson, who has twice undergone Tommy John surgery since he last pitched in the big leagues Sept. 2, 2006, was pitching as the closer for the Iron Pigs. In 25 appearances, he was 2-2 with 12 saves and a 2.43 ERA. He allowed 20 hits, 12 walks and struck out 34 in 29 2/3 innings.

The 26-year-old Canadian was 1-4 with a 7.47 ERA in nine games (eight starts) in 2006.
