PHOENIX -- When the season started, outfielder David Peralta was not really on the D-backs' radar screen.
He is now.
Since coming up from Double-A Mobile and making his big league debut on June 1, Peralta leads all rookies in average with a .331 mark and is third in hits with 40.
"He's got a good swing path," D-backs manager Kirk Gibson said. "He's very short to the ball, he swings down through the ball. You don't see him dipping like you see some guys do. He stays pretty short, he's aggressive, he recognizes the ball pretty good."
Peralta was a pitching prospect up until a couple of years ago before converting to the outfield.
"He's done a lot of good things," first baseman Paul Goldschmidt said. "He works hard, he plays hard. He's always doing early work, I see him out in the outfield working with [outfield coach] Dave McKay working on stuff."
Peralta was out of the lineup Tuesday.
"Actually after his last at-bat [last night] he came in and I saw him down there stretching his groin," Gibson said. "He's fine, I saw him in there working out last night, but just trying to be proactive and trying to give him time to recover. He's been playing hard and he's been on base a lot."
D-backs announce All-Star Teacher winner
PHOENIX -- Elizabeth Zipp has been selected to represent the D-backs in the "Target Presents PEOPLE All-Star Teachers" campaign, which celebrates current and retired teachers who make an impact on the lives of their students and communities.
Zipp spent time in Cuba as an undergrad and, while there, realized her desire to help children take control of their lives and not let an impoverished background determine their future.
It is still that experience that motivates her to this day.
Zipp began her teaching career when she was accepted into a national teaching program for the 2011-12 school year and since that time she has been recognized for her commitment to her students and school.
Zipp will join one winner representing each of the 30 MLB clubs to be included in All-Star Week activities and recognized during the pregame ceremony of the 2014 MLB All-Star Game -- Tuesday, July 15 with pregame ceremonies beginning at 7:30 p.m. MT on FOX from Target Field in Minneapolis.
• D-backs catcher Miguel Montero got a day off Tuesday. Montero came into Tuesday leading all catchers in innings caught with 705 2/3.
"He's starting to get tired," Gibson said. "I can tell."
• Gibson was able to speak with GM Kevin Towers, who had surgery performed on his vocal chords Monday in New York.
• First baseman Paul Goldschmidt has 33 doubles, the most hit by a D-backs player before the All-Star break in franchise history. The previous mark of 32 was held by Luis Gonzalez in 2003.
• Vidal Nuno became the 10th different pitcher to start a game for the D-backs this year. They used nine in 2012 and 2013.
