Matt Chaffee

Lefthander Matt Chaffee worked hard to overcome a torn labrum and has been impressive late in the year as the Wildcats' closer. His fastball sits in the 90-92 mph range and has a three-pitch mix with a curveball he can throw for strikes and a changeup. There's no denying Chaffee's stuff, so it's just a matter of how much teams worry about his medical history.
