The veteran lefty starter was an 11th round pick of the Chicago White Sox in the 2011 draft out of the University of Hawaii at Manoa in Honolulu.  He moved to the Astros organization and spent almost all of last summer in High-A Lancaster, before making one appearance for AAA Oklahoma City. Walters’ best stint in organized ball came with the Sox’ Class A Kannapolis team in 2012.  He had a 2.88 ERA for them in 13 starts with a 3-3 record.  He struck out 69 in 72 innings for the Intimidators.
