The Mets reportedly have free agent lefty reliever Tim Byrdak "on the rader". Byrdak, or "The Byrdman" as I wish him to be called, turned 37 in October and is a LOOGY of a fairly dramatic sort. Here are his career numbers against righties and lefties.
The Byrdman walks a lot of batters regardless of their handedness, but in general he's quite good against lefties and unspeakably awful against righties. A cheap and effective LOOGY is a good thing to have, and if the Mets do sign Byrdak they'll expect him to compete with Taylor Tankersley for a bullpen spot in spring training.
