Alfredo Figaro is a 28-year-old Dominican righthander who has split his seven-year professional career between the Tigers and Orix in Japan's Pacific League. He's made 35 appearances (31 starts) for Orix since the start of the 2011 season and posted a 3.31 ERA over 187.2 innings, walking 2.6 and striking out a little less than six batters per nine innings.
Before heading to Japan Figaro appeared in a few games for the 2009 and 2010 Tigers, putting up a 6.54 ERA over 13 appearances. He has a 3.24 ERA over 129 career appearances in the minors, counting his time in Japan. FanGraphs says he's got a low-90's fastball, slider and changeup.
Figaro is probably more likely to serve as organizational depth than a key member of the 2013 Brewers, but he's an interesting low-risk acquisition either way. If he does turn out to be a major league contributor, the Brewers would have control of his services for six seasons.
