After two years at Merced Junior College, Aguilar was selected in the 30th round of the 2005 amateur entry draft by the Milwaukee Brewers. However, before ever touching a baseball field, Aguilar was forced to undergo Tommy John Surgery. After recovering from Tommy John, Aguilar regained form, joining Bervard County, the High A affiliate of the Milwaukee Brewers. In 19 appearances as a closer, Aguilar was unhittable as he pitched 25 innings, posting a 0.35 ERA and sitting down an impressive 25 batters on strikes on his way to earning 13 saves. Aguilar was then promoted to class AA, where he continued his success with a 3.08 ERA, while striking out 42 hitters in just 38 innings. Aguilar joins the Chico Outlaws, bringing some impressive numbers to the team. He has a career ERA of 3.85 with an amazing 287 strike outs in only 247 innings, equating to 10.5 strikeouts per nine innings. Aguilar looks to bring his powerful fastball to the Outlaws in 2010 as they search for the first championship in North American League History.
