In addition to Mr. Ponson, the Yankees added another pitcher today, claiming Oneli Perez off waivers from the Indians today, as reported by Peter Abraham. Abraham passed along the Yankees press release:

The Yankees claimed RHP claimed right-handed pitcher Oneli Perez off waivers from the Cleveland Indians and optioned him to Double-A Trenton. Perez, 24, has appeared in 21 games combined this season at Triple-A Charlotte (White Sox) and Triple-A Buffalo (Indians) to go 0-1 with two saves and an 8.49 ERA (29.2IP, 48H, 28ER, 17BB, 34K) in his first action at the Triple-A level.

He was originally signed as a non-drafted free agent by the San Diego Padres in 2001 as a first baseman. Since converting to pitcher in 2003, Perez has gone 24-12 with 37 saves and a 2.65 ERA. In order to make room on the 40-man roster, the Yankees transferred right-handed pitcher Jonathan Albaladejo (right elbow stress fracture) to the 60-day disabled list.

Chad Jennings has a little more.
