Lawler has played two years of minor league baseball thus far in his professional career. In 2007, Lawler split time between the Milwaukee Brewers’ Rookie Level affiliate in Arizona and the club’s High Level A affiliate in West Virginia. While in Arizona, Lawler posted a 3-0 record with 3 saves and 20 strikeouts in 13.2 IP before being called up to High A. In 2009, Lawler pitched for Sioux Falls and finished 4-2 with a 5.03 ERA and 39 strikeouts over 39.1 innings pitched. The Diablos are hoping that this set-up man can come in and add valuable depth to the bullpen.
