"In Minor League camp, there's no one watching but the coach," Locante said. "You come over here and there's fans, there's front-office people, everyone is watching so you just have to focus more and not let it get to you. Once you let a couple go, then it's the same game; home plate is still 60 feet, 6 inches away."
D-backs manager Chip Hale only caught the tail end of Locante's session Saturday, but he had seen the ones he threw prior to camp opening, and pitching consultant Dave Duncan told Hale that he was impressed with how Locante looked.
"He has electric stuff," Hale said. "He's got a great arm."
Selected in the 11th round of the 2011 First-Year Player Draft, Locante improved his command last year, and in his second straight year with Class A South Bend, he went 3-0 with a 1.53 ERA in 43 relief appearances.
