Phenom Bauer promoted to Triple-A

DENVER -- The D-backs promoted top pitching prospect Trevor Bauer to Triple-A Reno on Thursday, and he is slated to start for the Aces on Friday against Oklahoma City.

Bauer was Arizona's top selection (third overall) in the 2011 First-Year Player Draft.

The right-hander was impressive in big league camp during Spring Training and has been dominating Southern League hitters.

In eight starts for Mobile, Bauer was 7-1 with a 1.68 ERA and he allowed just 33 hits in 48 1/3 innings, while striking out 60 batters.

"I wouldn't say he completely overmatched Double-A," D-backs GM Kevin Towers said. "But I think if you look at his numbers, we wanted to put him in an environment where he probably was facing a little better competition, a little more of a veteran hitter, smaller ballpark where it's going to be a little more difficult for him."

Bauer drew lots of attention during the spring for his unique pregame routine, which includes long tossing almost from foul pole to foul pole.

Gibson shortens batting practice time

DENVER -- In an attempt to help his team not press during its recent slump, D-backs manager Kirk Gibson decided to reduce the team's time in the batting cage.

Typically, each of the groups hit for 15 minutes, but Gibson reduced it to 10 minutes.

"It's way less swings," Gibson said.

And that means less time to think, or overthink as the case may be.

"We just feel like our personalities when you get frustrated and things are going good you work harder," Gibson said. "So we tried to simplify our thought process and our physical stuff."

It's something that his players realize as well.

"It's hard for everybody, because everybody wants to contribute," catcher Miguel Montero said of the struggles. "Things haven't worked out the way we want them to, so we keep pushing harder and harder. Let's try to do less and things are going to be better."
