Martinez has been one of the biggest eye-openers in minor league camp, assistant general manager Benny Looper told CSNPhilly.com
. "He trimmed up his body and has shown better bat speed," Looper said. "Whatever he did this winter really worked. He has better reactions at third base."
Martinez was a 2011 second-round pick out of the University of Miami. He finished last year hitting .272/.317/.362 with two home runs and six stolen bases for High-A Clearwater. The Phillies will likely start him off at Double-A and hope some of the improvements they see in camp will translate to results in actual games.
