Pollock looks to regroup after slow start

PHOENIX -- If D-backs outfielder A.J. Pollock were to go three games without a hit in, say, mid-June, it would not raise any eyebrows, or cause him any stress.

But when you go hitless for three games and those three are the first three of the season and there's a week between the second and third games, well, a person can start to put a little pressure on himself.

Pollock went 0-for-6 in the D-backs' home opener on Monday and is 0-for-13 through three games. On Tuesday, manager Kirk Gibson reminded him to relax.

"One of the things about the game is to keep things in perspective," Gibson said. "He had a really good spring for us, he swung the bat good. What you don't want to do is get to the point where you're overexaggerating what's happened or what's happening. Just try and relax and trust the process and trust what you've worked on so far."

Pollock is big on focusing on the process of an at-bat, rather than the end result. In other words, controlling what he can control -- his approach -- and trusting that it will translate into results.

That's what he is working to remind himself of now, and also that he will eventually snap out of it.

"It's going to happen," Pollock said. "As long as I relax and let it happen, it's going to happen. It's a new day. I've been in this spot before. The worst thing yesterday wasn't my 0-for-6, it was that we lost."

Parra on right track against left-handers

PHOENIX -- Gerardo Parra's struggles against left-handers last year were well documented.

Parra hit just .198 against southpaws and with no homers and four RBIs.

Determined to change that, Parra made some adjustments in his stance, keeping his hands closer to his body and relaxing his front leg more. The idea was to get him to use his hands more and stay back, rather than fly open.

It's obviously too soon to say if the changes are a success or not, but Monday's home opener was a good start, as Parra singled and drove in two runs against Giants lefty Madison Bumgarner, putting him halfway to his total from last year.

"I feel more comfortable against them," Parra said. "I don't put too much pressure on myself against them now."

D-backs manager Kirk Gibson played Parra against lefties more often during Spring Training and also put him in simulated games against them.

"He changed his whole setup," Gibson said. "His setup is different, his hands are different, he's trying to put himself in better position."

So far, so good.

Trumbo comes through in home debut

PHOENIX -- You only get one chance to make a first impression, and D-backs outfielder Mark Trumbo did not want to waste his.

Trumbo, who was acquired from the Angels in a December trade, played in his first home game on Monday and went 3-for-5 with a pair of RBIs.

"It's always nice when you have some success, especially this being the first home game with a new team," Trumbo said.

Even before the in-game success, the sellout crowd gave Trumbo a nice ovation when the starting lineups were announced.

"The reception I got from the fans was great to hear," Trumbo said. "The energy that was in the stadium last night was awesome. I think we definitely fed off that. Unfortunately, in the end, we didn't get it done from our end, but I think everyone that came brought it."
