Aroldis Chapman's fastball hits 105 mph? Really? - Fantasy Windup: A community for fantasy baseball news and strategy - USATODAY.com Is this guy the next Bob Feller? Reaching 105 MPH is simply crazy. Can't wait to see what he can do against Major League players. Really glad that the Reds didn't rush this guy, he had control problems when he first signed with the Reds, but he spent most of the year in the Minors to fix that issue.
