When former hitting coach Rudy Jaramillo balked at a contract extension and bolted for the Chicago Cubs following the 2009 season, the Rangers faced the difficult task of replacing someone who had been here for 15 years and was thought of as the best in the business. GM Jon Daniels considered hiring unproven fan favorite Rusty Greer, but he ultimately pulled the trigger on Clint Hurdle, who led the Colorado Rockies to the World Series in 2007 during his eight years as manager. While the offense hasn't been perfect this year, the combination of Hurdle's success and Jaramillo's rough year in Chicago proves a change was needed. The best evidence can be found in Josh Hamilton, who struggled last year while Jaramillo tried to eliminate his toe-tap and then made the adjustment under Hurdle and became an MVP candidate.
