Drew misses opener with abdominal strain

DENVER -- As expected, Stephen Drew was out of the D-backs' starting lineup Friday as he continues to battle an abdominal strain.

Willie Bloomquist got the start in his place at shortstop, and D-backs manager Kirk Gibson said he was not sure if Drew would be available to pinch-hit if needed.

"It's pretty frustrating," Drew said of missing the opener. "But I look at it like we have 162 games, so Opening Day is great, but at the same time, it's a long season. It's not just a sprint, it's a marathon. If I can get back to where I need to be the next two or three days and can play the rest of the season, that's a big key."

Bloomquist did not play a lot of shortstop during the spring and saw action in just one game there last year. However, he has played 150 games there over his eight-year career, including 38 in 2009 for the Royals.

"We'll find out," Bloomquist said when asked if he was comfortable at the position. "It's one of those things where when you bounce around as much as I do, you really never get completely comfortable in one spot before you're off to the next spot. So it's just one of those things where you learn to deal with it and be comfortable being uncomfortable. I'm just going to go out and play as best I can."

Gibson said he had no reservations about Bloomquist's ability.

"He's gotten enough action out there," Gibson said. "He's played enough over there, he's a gamer. I'm very comfortable with him over there."

Hernandez wins D-backs' eighth-inning role

DENVER -- There are three defined roles in the Arizona Diamondbacks' bullpen.

J.J. Putz will be the closer, David Hernandez will pitch the eighth inning with a lead and Joe Paterson will be the left-handed specialist. As for the rest? You'll have to wait and see.

"The other guys will be less defined initially," D-backs manager Kirk Gibson said.

It was more than just a strong spring by Hernandez that won him the eighth-inning setup role.

"Just based on his stuff," Gibson said. "He's got power stuff, he can overpower people. It's just an organizational decision. That's how we're going to do it to start out with."

Aaron Heilman, Juan Gutierrez, Sam Demel and Kam Mickolio are the other members of the 'pen.

Gibson to use different lineups early on

DENVER -- Kirk Gibson waited until Friday morning to set his Opening Day lineup, and it contained a couple of surprises.

Despite a red hot spring by Russell Branyan, Gibson elected to start Juan Miranda at first base. Miranda was acquired by the D-backs in the off-season from the Yankees where he was blocked at first by Mark Teixeira.

"I think Juan's a little better defensively and this is the way I decided to go," Gibson said. "I think that Juan Miranda will get a lot of playing time, and we'll see what he can do."

So does that mean Miranda is the starting first baseman?

"Today he is," Gibson answered.

Has he said anything to his first basemen about playing time?

"I didn't tell them anything," Gibson said. "I tell them to check the lineup. That goes for everybody."

The other surprise was Gibson's decision to hit Willie Bloomquist in the leadoff spot. Bloomquist started in place of injured shortstop Stephen Drew.

"He's been doing a great job of it all [spring]," Gibson said. "I considered moving him to second because he handles the bat well."

The D-backs' lineup could fluctuate a lot in the early part of the season.

"It's going to take us some time to work our way into that," Gibson said of a set lineup. "I'm not just going to say this is the lineup and stick with it. I'll move it around for right now. We're not in a position to set our lineup yet."

D-backs hire Krause as special assistant

DENVER -- The D-backs on Friday hired Jerry Krause as a special assistant in the scouting department.

Krause will evaluate players on all levels, including amateur players for the First-Year Player Draft. He will report to Jerry Dipoto, who oversees the club's scouting and player development departments after serving as interim general manager last year.

"Jerry brings tremendous experience, a creative mind, unbridled passion for the game of baseball and a no-job-is-too-small attitude to the table every day," Dipoto said in a statement. "We can all learn from him and I look forward to exploring the different ways in which he can positively impact this organization."

Krause had been working as a scout for the White Sox where he restructured their scouting in the Dominican Republic and Venezuela. He has also worked as a scout for the Indians, A's, Mariners, Yankees and Mets.

Prior to that, Krause served as general manager of the NBA's Chicago Bulls from 1985-2003. The organization won six NBA championships during his tenure.
