NEW YORK (WFAN/AP) – Mets reliever Tim Byrdak is set to undergo surgery on Tuesday to repair a torn meniscus in his left knee, according to CBSSports’ Jon Heyman.

Byrdak, 38, was slated to be the club’s lefty specialist, but he’s now expected to miss six week, according to the Mets.

“Obviously this will impact our left-handed relief,” general manager Sandy Alderson said Monday. “We’ll just have to evaluate things as we go forward. But I would suspect that Byrdak would not be available to us for some portion of the regular season. We’ll have to accommodate that.”

The Mets now have a gaping hole in their bullpen, and Daniel Herrera and Garrett Olson are expected to compete for his spot on the roster, should it be available. Lefty Josh Edgin is also moving to major league camp.

Who should take Byrdak’s spot in the ‘pen if he has to miss time? Let us know…
