O'Brien displays power with two-homer game

PHILADELPHIA -- In his first week in the big leagues this year, D-backs outfielder Peter O'Brien has seen a steady diet of breaking balls.

"You get up here, and they're pitching you like you've been in the bigs for 10 years," O'Brien said. "It's good, though, I like the competition. It's only going to make me better, so I'm going to keep going out there and keep trying to have good AB's and try to help the team win."

O'Brien certainly did that Friday night when he blasted a pair of home runs and drove in four to help lead the D-backs past the Phillies, 10-2, at Citizens Bank Park.

After a cup of coffee in the Majors last September, O'Brien mashed 17 homers in 51 games for Triple-A Reno before being called up last Friday.

Heading into the game with the Phillies, O'Brien had one hit in 15 at-bats and had struck out seven times. The one hit was a homer against the Marlins on June 12.

After Friday, he has three hits in 20 at-bats with all three being homers.

"I don't think it's been tough to stay positive," O'Brien said of his start. "I won't say that the couple hits don't let me take a little bit of a deep breath. I feel good.

"I think the biggest thing is just kind of getting comfortable. That's what I've been saying since I've got here -- new ballparks, new arms I haven't seen. I've talked to a lot of guys, and I think the biggest thing is just kind of being in the moment and get comfortable and everything will start to come around."

O'Brien's first homer came with two on in the fifth, and his second was a solo shot in the seventh.

O'Brien goes back-to-back

"He got two strikes, and he did a good job just trying to put a ball in play," D-backs first baseman Paul Goldschmidt said of O'Brien's first homer. "... As big and strong as he is, he was able to get it out of there. He did a good job hitting it out right there, and then he hit another one."

When the D-backs called O'Brien up, manager Chip Hale committed to playing him regularly so the organization could get a good feel for what he could do.

Still, O'Brien admitted he tried to do too much too soon.

"You kind of get amped up and want to get in there and do damage right away," O'Brien said. "I think that's where being comfortable comes in, just kind of taking a step back, taking a deep breath and staying with that same plan and that same routine that makes you successful."
