Philadelphia closer Brad Lidge, who has been on the disabled list since spring training to continue his recovery from offseason elbow and knee surgeries, will be activated in time for the Mets series Phillies general manager Ruben Amaro, Jr., announced on Wednesday.

Manager Charlie Manuel said he's uncertain whether Lidge will regain the closer role right away. "I'll play it by feel," Manuel told Philadelphia reporters.

Ryan Madson has been serving as the closer. On Wednesday in San Francisco, he blew his second save in six attempts, and his ERA is 7.00 in nine games. The Phillies came back to pull out a 7-6 win.

Reliever Antonio Bastardo, who has a 1.69 ERA in seven appearances and has performed well, is expected to be optioned to the minors because he has options left.

Phillies shortstop Jimmy Rollins, a perennial thorn in the Mets' side, still is on the DL with a right calf strain, though he is now eligible to come off.
