PHOENIX -- D-backs center fielder A.J. Pollock will need surgery on his right hand after suffering a fractured fourth metacarpal bone when he was hit by a pitch against the Reds on Saturday.
Manager Kirk Gibson said the surgery would take place in the next few days. Pollock was placed on the 15-day disabled list Sunday.
"The bone is kind of upwards," Gibson said. "They're going to pull it, traction, straighten it out, probably put a plate on it. Ideally, they'd like to put a pin in it, I guess, but I don't know if they're going to be able to do that."
Gibson said the timetable for Pollock's return has not been set, but it could be anywhere from five weeks to two months.
"It's a guess," he said.
As for Pollock, the D-backs' leading hitter is taking the injury as well as anyone can. He has suffered a serious injury in the past. In 2010 -- his first year with the D-backs organization -- Pollock had surgery on his right elbow to repair a fractured growth plate.
"The elbow one was a freak kind of thing," Pollock said. "That one was just a little more difficult because … it was a strange one for the doctors to kind of wrap their heads around, so that was a little more nervewracking."
"I talked to the hand guy. He's very confident and everything. So I'm just a little more confident going in."
The D-backs called up outfielder David Peralta from Double-A Mobile on Sunday morning to take Pollock's roster spot.
D-backs' Venezuelan starters set record
PHOENIX -- Five Venezuelan players who started in the D-backs lineup on Sunday -- Gerardo Parra, Miguel Montero, Martin Prado, David Peralta and Ender Inciarte -- recorded hits, which is a Major League first.
Four of the hits came in a fourth-inning rally against the Reds. Montero rocketed an RBI double -- his second hit of the game -- off the right-field wall to score the D-backs' first run of the inning. Prado followed with a single.
After a single by third baseman Eric Chavez, Peralta, making his Major League debut, knocked his first big league hit -- a single to center field.
Inciarte followed with an RBI single, scoring Prado and wrapping up the scoring for the inning.
Parra got his hit later, singling to left field in the seventh inning.
Only the Giants have come close to matching the D-backs' feat. On Sept. 1, 2013, they had five Venezuelan players get a hit, but one of them, Marco Scutaro, was a pinch-hitter.
Peralta called up from Double-A
PHOENIX -- With center fielder A.J. Pollock on the disabled list with a fractured right hand, the D-backs are looking for answers in the outfield.
The team took the first step by calling up outfielder David Peralta from Double-A Mobile on Sunday. Just a few hours after flying to Phoenix, Peralta was in the starting lineup, playing left field.
"I got a call from [Mobile manager Andy Green], and he just asked what I'm doing," Peralta said. "[He said] 'I need to talk to you.' I was kind of excited. I thought I was going to go to Triple-A.
"He just came to my room and gave me the big news, like, 'Hey, you don't need Triple-A. You're going to the big leagues.' I'm still in shock."
Peralta was playing well in Mobile, hitting .297 and had an on-base-plus-slugging mark of .839.
Peralta, who was a pitcher in the Cardinals organization before suffering a left shoulder injury, is in his second year as a member of the D-backs organization. Before the D-backs signed him and sent him to Class A Advanced Visalia in 2013, he was playing with the Amarillo Sox of the American Association -- an independent league.
"I got released in '09 with the Cardinals," Peralta said. "I had two surgeries on my shoulder. So I just decided to give up pitching and start swinging. It's much better swinging."
Manager Kirk Gibson moved Ender Inciarte, who had primarily played left, to center field, replacing Pollock. Inciarte has played five games in center field for the D-backs this season. In the Minor Leagues, he played 431 of his 610 games in center.
Gibson said Inciarte, Peralta and right fielder Gerardo Parra could all play center if needed, but he was hesitant to put Peralta in center field on his first day with the team.
"A.J.'s been in the [outfield] rotation virtually every day," Gibson said. "So when you take that way, obviously it's going to change things. We have to figure out what the best way to proceed is."
Pennington in lineup after missing four games
PHOENIX -- Cliff Pennington is back in the D-backs' lineup after missing four games with a right hand injury.
Pennington suffered the injury when Padres shortstop Everth Cabrera slid into his hand on May 27.
The injury was not serious, and manager Kirk Gibson said Pennington was available to play previously if he was needed, but Sunday marked his first day back in the lineup.
Pennington is hitting .257 (18-for-70) in 32 games this season. He may see more team with regular shortstop, 22-year-old Chris Owings, struggling. Owings hit .217 (20-for-92) in May.
"Pennington's been banged up," Gibson said. "I'm going to play him today. The slide by Cabrera, he jammed his thumb pretty good.'
