D-backs won't bring top pick Bauer to bigs

PHOENIX -- Trevor Bauer, the D-backs' top pick in the 2011 First-Year Player Draft, will not be called to the big leagues this year.

"It's probably good for him just to take a breather and coming back up here and learning something more, sometimes that can be overkill for a young player," D-backs general manager Kevin Towers said.

Bauer, the No. 3 overall pick, signed quicker than most first-round picks and quickly moved up from Class A Visalia to Double-A Mobile, where he pitched well in his first three starts before struggling in his next two.

In his final start of the year on Sunday, Bauer was the winning pitcher as the BayBears captured the Southern League title.

The 20-year-old is expected to contend for a spot in the rotation next year at Spring Training.

"I think he finished on a strong note, which is good," Towers said. "He's been through a lot. He's going to be in the mix to be one of our pitchers next year, so I think the rest and getting mentally prepared and physically prepared will be a good thing."

Top prospect Parker called up to D-backs

PHOENIX -- The D-backs called up top prospect Jarrod Parker from Double-A Mobile on Monday.

The right-hander, who was the club's No. 1 pick (ninth overall) in the 2007 First-Year Player Draft, was 11-8 with a 3.79 ERA in 26 starts for Mobile, which clinched the Southern League title over the weekend.

"It's cool," said Parker, ranked 17th in MLB.com's Top 50 Prospects and second in the D-backs' organization. "The atmosphere is awesome. I just came from Double-A, we won the championship, we celebrated last night. It was a crazy night to find out I'm coming up after a win."

Parker's rise to the big leagues got sidetracked when he underwent Tommy John surgery in 2009. The surgery forced him to miss the entire 2010 season, and the rust showed early this season as he struggled with his command.

"I put together some solid starts in the second half, got a chance to come up here," Parker said.

Parker is expected to compete for a spot in the rotation next spring so the organization wanted to give him a taste of what the Majors were like. Arizona manager Kirk Gibson said it's possible Parker could see a few innings in relief during the season's final nine games.

"Itís been a long road back for Jarrod," Gibson said referring to Parker's rehab. "He started out earlier in the year not very good, because he hadn't pitched. He just needed to pitch. He's kind of started to learn some things and just turned from just being a thrower into more of a pitcher. We thought we was deserving to come up here and experience what we're going through and understand what it's all about in preparation for hopefully a bright future."

To make room for Parker on the 40-man roster, shortstop Tommy Manzella was designated for assignment.

Worth noting

• Despite Lyle Overbay's impressive numbers against Monday's Pirates starter Jeff Karstens, D-backs manager Kirk Gibson elected to start Paul Goldschmidt at first base. "He seems to have a lot of character, and he just seems have some pretty good moments," Gibson said of Goldschmidt.

• Gibson said that he will likely keep his pitchers in rotation despite Thursday's off-day, which would mean each would get an extra day off between starts.

• The National League West race has tightened over the past week and Gibson said he is watching closely to see how his team responds. "In my career, I just loved the feeling," he said. "There's probably many people that would not love the feeling of all that pressure. It's hard to explain, but I think it's one of the ways that, in the end, you measure yourself of how you reacted and who you were and how you contributed in those situations, not only by yourself, by your teammates, but by your opponents as well."
