Background: Zimmerman has an unlikely resume for a prospect. He is a Canadian who was undrafted out of Texas Christian. While coaching in British Columbia, he earned a master's degree in business administration. His only pro experience before last season was in the independent Northern League in 1997. Zimmerman's younger brother, Jordan, is a lefthander on the Mariners' 40-man roster. Strengths: Picture Kerry Ligtenberg, including the independent league background, and you have Zimmerman. He has a sinking 90-92 mph fastball and he can spot the corners. Zimmerman's out pitch is a tight, late breaking slider that is an above average major league pitch. His maturity level and composure on the mound are excellent. Weaknesses: Zimmerman is obviously old for a prospect, especially one with just 77 innings of minor league experience. His changeup has not been a factor working out of the bullpen. The Future: The Rangers think Zimmerman has a strong chance to make their major league team in 1999. Their bullpen is hardly a strength and Zimmerman's slider can get big league hitters out now.
