Matt Wieters has yet to become the kind of hitter many were projecting before his MLB arrival in 2009. Wieters hit .288/.340/.412 and nine homers in 2009 and .256/.318/.365 with four homers this season. Krem's Sports Blog offers three reasons why Wieters has struggled. Reason #1: He's not hitting the ball as hard. Reason #2: He's hitting more ground balls. Reason #3: He's struggled with fastballs.
