The Brewers announced that they claimed right-hander Arcenio Leon off of waivers from the Astros.

Leon spent the 2012 season pitching in relief for Houston's Double-A affiliate. The 26-year-old appeared in 44 games, posting a 4.38 ERA with 8.2 K/9 and 4.7 BB/9 in 63 2/3 innings. He has had trouble limiting walks in eight seasons as a professional, as his career rate of 5.2 BB/9 indicates.
