 In 2008, Jiménez posted a very robust ground-ball percentage of 54.4%, a testament to this pitch's effectiveness and making him an ideal pitcher for Coors Field, a ballpark known for extra-base hits.Jiménez was known to throw a split-finger fastball and an occasional forkball, having deceptive downward movement in the 85–88 mph range.The changeup thrown by Jiménez also exhibited strong "sinking" action, so much so that television commentators unfamiliar with Jiménez often had trouble distinguishing his change-up from a sinking fastball or a split-finger fastball.
