The Phillies today placed righthanded relief pitcher José Contreras on the 15-day disabled list with a right forearm strain, retroactive to June 20.
To fill Contreras' spot on the 25-man roster, the Phillies brought up lefthander Juan Perez from Triple A Lehigh Valley.
Contreras, 39, who started the season as the Phillies' closer, is 0-0 with a 3.86 ERA in 17 games this season. He has converted all five of his save opportunities while holding opponents to a .220 batting average (11-for-50) in 14.0 innings. Contreras previously spent a month on the disabled list this season with a right flexor pronator strain (April 25-May 26).
Perez has gone 0-3 with four saves and a 3.52 ERA in 28 appearances with Lehigh Valley this season. The 32-year-old has struck out 41 batters in 30.2 innings (12.17 SO/9.0 IP) and held left-handers to a .184 average (7-38). He is 0-1 with a 5.17 ERA in 24 career major league appearances, all with the Pittsburgh Pirates over the 2006-07 seasons.
