The Milwaukee Brewers signed free agent left-handed reliever Mike Gonzalez to a one-year contract today. To make room on the 40-man roster, the team designated right-handed pitcher Arcenio Leon for assignment.
Leon, 26, was acquired off of waivers from the Houston Astros in November. The Venezuelan right-hander has yet to make his big-league debut, but did get a few innings at Triple-A in 2011.
Leon made 44 relief appearances for the Astros' Double-A club in 2012, posting a 4.38 ERA and 8.2 K/9 rate in 63⅔ innings. The right-hander has never had trouble missing bats in his minor-league career but has also never had trouble missing the strike zone, walking over five batters per nine in his eight seasons of professional ball.
It seems unlikely that Leon will find himself in the Brewers' bullpen at any point in 2013, but with the way things went for their pen last season you cannot rule anything out.
