PHOENIX -- The D-backs will likely go with a shortstop-by-committee approach as they try to fill the huge void left by the season-ending ankle injury that Stephen Drew sustained on Wednesday night.

"You're not going to replace Stephen," general manager Kevin Towers said.

To take Drew's place on the roster, the D-backs selected the contract of infielder Cody Ransom from Triple-A Reno. The 35-year-old Ransom will see time at shortstop, as will Willie Bloomquist; Ryan Roberts and Geoff Blum are also candidates for playing time.

Filling Drew's shoes will be tough, and the team also has to overcome the emotional hurdle of watching one of their most valuable players sustain a grotesque injury and knowing that they will have to make it through the next two months without him in the lineup.

Towers said that the mood in the front office on Thursday was more somber than usual and that he was at the ballpark until 2 a.m. talking to manager Kirk Gibson and his coaching staff following the injury.

"It takes time," Towers said. "It's not something you get over in a half-hour or an hour when you lose someone like him. Knowing these guys here, they'll rally together, and if anything, I think they'll find a way to find that spark and pick up the slack and hopefully do some good things over the next couple of months."

Veteran Ransom called up after Drew's injury

PHOENIX -- For Cody Ransom, it's a case of "been there, done that."

The 35-year-old infielder had his contract selected from Triple-A Reno on Thursday, and he is one of several players who will try to fill in for shortstop Stephen Drew, who was lost to a season-ending ankle injury on Wednesday.

Ransom has appeared in 219 Major League games between stints with the Giants, Astros, Yankees and Phillies. He also has experience filling in for a star player. He was the Yankees' Opening Day third baseman in 2009, when Alex Rodriguez was on the disabled list with a hip injury.

"I'm not looking for any infielders," general manager Kevin Towers said, referring to the barren shortstop trade market. "I don't see much out there that's available, and Cody's got experience. He's one of the best hitters in Triple-A baseball right now. Why not give him a crack at it? It's not like we're bringing a young kid up. He's not going to be in awe of this situation, and hopefully he takes advantage of this opportunity."

Ransom was hitting .331 with 28 doubles, 26 homers and 89 RBIs in 92 games for Reno. He led the Minor Leagues in RBIs and was second in extra-base hits, with 57.

"It's probably been one of the better years of my career so far," Ransom said. "It's been more consistent than I've been, and it's a lot of fun to play this year."

Having a player with experience waiting in the wings is one of the reasons the D-backs increased their Triple-A payroll this year, from around $500,000 to around $900,000. Players who have more experience tend to cost more, but the D-backs do not want to rush any of their younger prospects because of injuries at the big league level.

"Hopefully he continues to play good defense and swing a hot bat like he's done in Reno all year long," Towers said.

Drew injury does not alter Towers' Deadline plans

PHOENIX -- The season-ending injury to Stephen Drew has not altered general manager Kevin Towers' approach to the July 31 non-waiver Trade Deadline.

"Pitching is where we have to get better," Towers said.

Though Towers would love to add a starting pitcher, the way the market is shaping up, it looks more like any starting help will have to come within the system. Bullpen help, on the other hand, could be where the D-backs make a move.

One thing Towers is not prepared to do is mortgage the future by trading any of the organization's top prospects for a quick fix.

"The last thing that I want to do is do something crazy that's going to hurt us down the road," he said. "Do we need to add pieces? Yes. You have to really evaluate the rest of the division more than anything, especially [the Giants]. They're not going to be the same team two weeks from now. Their pitching is probably one of the best in baseball, and what is out there that we can do without pretty much [raiding] our system that makes us as good as them or better than them?"

If that move is not there, Towers won't make one just for the sake of making one.

"The effort is going to be there," he said. "I can't make any promises what's going to happen, but I'm not going to do anything dumb, either."

With the future in mind, should the D-backs bring up one of their prized pitching prospects, such as Jarrod Parker, Tyler Skaggs or Patrick Corbin, it will be to stay and not just to make a spot start or two.

It is different with someone like Barry Enright, who has big league experience, and who the team sent right back down after a poor start on Tuesday.

"So when you use some of the young guys that come up here with little or no big league time, they're more apt to stay here," Towers said. "We're committed to them. It will be a full-time commitment to those youngsters."
