NEW YORK -- Two of the three players the D-backs acquired from the Pirates on Saturday have reported, with Ryan Church expected to join the team Tuesday.

Players have 72 hours to report to their new club once they are traded.

"I told him we're not in a roster crunch, so whatever works best for him," interim general manager Jerry Dipoto said.

Once Church reports, the D-backs will need to clear a spot on the roster for him, with the decision likely to be between infielders Augie Ojeda and Tony Abreu.

The reason the team elected to send down outfielder Cole Gillespie when infielder Bobby Crosby joined the team Sunday was because Ojeda and Abreu are both switch-hitters, and the team wanted to swap out right-handed bats with Crosby and Gillespie to keep flexibility on the bench.

"Cole is going to go down and play every day for the last month and probably deserve to come back in September," interim manager Kirk Gibson said.

Gibson foresees LaRoche's big day

NEW YORK -- Before Sunday's game against the Mets, D-backs interim manager Kirk Gibson had a few words for first baseman Adam LaRoche.

"I actually said to him before the game, 'You're getting ready to get hot, aren't you?'" Gibson said. "I just sense that he's starting to feel better."

LaRoche wound up hitting a pair of three-run homers in driving in a career-best six runs, as the D-backs routed the Mets, 14-1.

But before you think Gibson is psychic, it turns out this wasn't the first time he has said this to LaRoche.

"I've been wrong a few times," Gibson said with a smile.

LaRoche laughed after the game when reporters asked him about Gibson's pregame comment to him.

"He's always trying to jinx me," LaRoche said. "Don't listen to him. He's going to keep trying that, and I'm going to end up slapping him."

Both of the homers came off cut fastballs from left-hander Jonathon Niese. LaRoche said he's been rolling over and grounding out sliders and cutters of late, including his at-bat in the second inning when he grounded out to first.

"I finally stayed on a couple and got them up in the air," LaRoche said.

LaRoche also defended Niese's pitch selection in throwing the cutters on both homers.

"That is his bread-and-butter [pitch]," LaRoche said. "It's not like he was going against his game plan. That's the way he gets people out. That's the way he's got me out before. He just left a couple out over the plate."

Crosby joins D-backs day after first trade

NEW YORK -- Infielder Bobby Crosby joined the D-backs on Sunday, with outfielder Cole Gillespie being optioned to Triple-A Reno.

Crosby, 30, was the A's first-round pick in the 2001 First-Year Player Draft. Originally a shortstop, Crosby has also seen time the past two seasons at second, third and first, as well as one inning in right field.

"Shortstop is where I spent the most time and probably feel the most comfortable, but I feel comfortable at second and third and first," Crosby said.

Crosby was with the Pirates in St. Louis when he got word he had been dealt to the D-backs. He flew back to Pittsburgh, where his wife and family were, and then on to New York.

"It's been a crazy day and a half," Crosby said. "I didn't hear much, so I wasn't really expecting a move. I'd never been traded before, so I really wasn't expecting it. Sometimes change can be good, and I'm looking forward to a new start here."

D-backs interim manager Kirk Gibson said that infield coach Matt Williams will work with Crosby to get him used to the infield at Chase Field when the team returns home this week.

"We'll have Matty work him hard, get him used to that surface -- it's a pretty quick surface," Gibson said. "We'll watch him play a little bit and just kind of see where he fits in and define his role that way."

Crosby was issued jersey No. 1.

D-backs keeping tabs on pitchers' innings

NEW YORK -- The D-backs will look to limit the innings pitched this year of right-handers Daniel Hudson, Ian Kennedy and Barry Enright to the 175-185 range.

Despite the limitations, interim manager Kirk Gibson said the team will not have a problem filling innings down the stretch.

"I think we'll be OK," Gibson said. "I don't think we have to be skipping guys. I think we'll be able to manage it."

Said interim GM Jerry Dipoto: "This will be the first time they've been asked to take the ball every fifth day in September. We'll have to keep that in mind."

Worth noting

It was a good debut Friday for D-backs left-hander Patrick Corbin, who was acquired from the Angels in the Dan Haren trade. Corbin allowed two hits in five scoreless innings with eight strikeouts for Class A Visalia. ... Outfielder Justin Upton extended his hitting streak to 17 games with a single in the fourth inning Sunday.
