Goldschmidt's epic blast still reverberating

PHOENIX -- One day later, the D-backs clubhouse was still buzzing about the 470-foot home run that first baseman Paul Goldschmidt hit off the scoreboard in center field.

"That's probably the farthest I've ever seen one hit to dead center," veteran shortstop Cliff Pennington said.

It was an impressive blast to be sure, but it apparently was not the most impressive of Goldschmidt's professional career. That honor belongs to one he hit one night in Birmingham, Ala., in 2011, when Goldschmidt was playing for Double-A Mobile.

"The one he hit in 2011 in Birmingham makes last night's look like a wall-scrapper," said pitcher Wade Miley. "I was in the stands charting pitches that night and it was just like a rocket. We lost it in the night. It just went over the speakers they had way up in center field."

Outfielder A.J. Pollock, a teammate of Goldschmidt's in Mobile, remembers it well.

"It was just a blast, dude," Pollock said.

It just so happens that D-backs general manager Kevin Towers and his special assistant Mike Fetters were in the stands that night in Birmingham.

"It disappeared," Fetters said. "I couldn't even tell you how far it went, because it disappeared. It's one that I won't forget. It was a wow. To me, it was hit further and harder than he hit last night. The one he hit last night was gigantic. The one he hit in Birmingham was titanic. It was crazy."

Of course, there was one person in the clubhouse that was not overly impressed with it.

"I haven't gone back and looked at it," Goldschmidt said. "We've got a game to get ready for tonight."

Prado heating up after some motherly love

PHOENIX -- Martin Prado has been heating up at the plate of late after a tough start to the season.

In his last seven games, Prado has hit .409 with an on-base plus slugging mark of 1.318.

"He's swinging the bat good," D-backs manager Kirk Gibson said. "Hopefully history is going to repeat itself."

The history Gibson is referring to is how Prado heated up last season after a slow start.

Prado hasn't changed his swing, but he has been a little more aggressive in his approach, picking a spot when he'll jump on a pitch earlier in an at-bat than usual.

Prado hit his first home run of the season on Tuesday and followed up with another the next day.

During his struggles Prado received no shortage of advice, including some from his mother, who will be coming to town next week, but has been talking to him regularly on the phone.

"She's always trying to fix my swing," Prado said. "I said, 'Mom, you don't know anything about my swing.' She always has the right words to make me feel better and to help me understand clearly. Even when I struggle, she still thinks I'm the best."

Except when it comes to his swing, of course.

"She told me two days ago she was watching one of our games and, 'It looks like you're too close to home plate. You should separate from home plate,'" Prado said. "I said, 'Mom, I was separate from home plate, now I'm getting closer to home plate."

Rehabbing Trumbo takes swings standing up

PHOENIX -- D-backs outfielder Mark Trumbo took 50 swings off a batting tee on Wednesday and again on Thursday.

It was the first time he has swung the bat standing up since being diagnosed late last month with a stress fracture in his left foot.

Previously Trumbo had taken swings while kneeling on one knee.

"As good as I could have hoped for," Trumbo said. "Everything felt good."

Trumbo has also begun to run on the AlterG treadmill, which offloads a percentage of a person's body weight. As of now, Trumbo is running on just 20 percent of his body weight.

Gibson, Price face each other as managers

PHOENIX -- D-backs manager Kirk Gibson served on the same Arizona coaching staff with Bryan Price from 2007-09.

Thursday night at Chase Field, Gibson squared off against him for the first time as an opposing manager as the Reds and D-backs opened a four-game series.

"He's got a great mind, he's got a great sense of humor," Gibson said. "He'll be up against the challenges that every manager [has]. He hasn't even managed 100 games yet. I think he has conviction in what he believes in. I think he has a good way of delivering that to his team."

Gibson served as bench coach for Bob Melvin while Price was the pitching coach. Price resigned in early May 2009 to protest the fact that Melvin was fired and A.J. Hinch was hired as manager.

Gibson stayed on Hinch's staff and eventually took over as interim manager one year later when Hinch was dismissed.

Price, meanwhile, joined Dusty Baker's staff in Cincinnati and was hired this past winter as manager.

"If you look at a team like his, you come in there with a new staff and a new manager," Gibson said. "He's probably much different than Dusty was. So it's going to take some time for them to understand each other and get synced up. I think they started off a little bit slowly and they've been OK. He won't give in. He's a very determined, smart individual, and he'll figure out how to make it work."
