"Mike has progressed up the ladder from the Frontier League to the Northern League, and this is the next step for him," said RedHawks Manager Doug Simunic. "He did a great job for us in 2007 and was a major part of our success. The Astros are getting a good, hard-nosed ballplayer who can do a lot of positive things on the field."
