The Athletics claimed 25 year-old righty Jon Meloan off waivers from the Pirates, according to CSN Bay Area (via Twitter). The A's are Meloan's fourth club this year, after he bounced around from the Indians to the Rays to the Pirates. And last year he went from the Dodgers to the Tribe in the Casey Blake deal. At three different Triple A stops this year he compiled a 4.57 ERA with 60 strikeouts and 28 walks in 65 innings. Meloan was considered a "potential power set-up man" for the Dodgers by Baseball America a few years ago.
