PHOENIX -- The Brewers placed veteran shortstop Cesar Izturis on the 15-day disabled list after he strained his left hamstring during Friday's 7-1 win over the D-backs, an injury that further depleted the team's thinnest position.

Cody Ransom, who had just joined the Brewers on Friday after being claimed off waivers, took over at shortstop following Izturis' sixth-inning departure. Ransom will start at short on Saturday. Edwin Maysonet, optioned to Triple-A Nashville to clear Ransom's roster spot, will rejoin the team. The Brewers already lost Opening Day shortstop Alex Gonzalez to a season-ending knee injury.

How many hits can the team absorb at that position?

"We can't take any more," manager Ron Roenicke said.

Izturis said he felt a tug in his hamstring running to second base on his sixth-inning double. When Corey Hart singled to left field, third-base coach Ed Sedar waved Izturis home, but the veteran felt another "grab" and instead held up, then rested his hands on his knees. After a visit from Roenicke, Izturis exited the game.

He was examined by a doctor at Chase Field before being immediately placed on the DL. Izturis was unsure about the severity of the injury.

"It's hard to tell," he said. "Right now, I'm really sore. We'll see [Saturday] how I feel." Izturis is the sixth member of Milwaukee's Opening Day roster to hit the DL in the first two months of the regular season.

"It's unbelievable," Izturis said.

Assistant general manager Gord Ash said the Brewers expected to get back a bit of Minor League shortstop depth on Saturday, when offseason acquisition Jeff Bianchi comes off the Triple-A DL. He is batting .346 in the Minors this season.

Ransom joins Brewers, thrust into starting role

PHOENIX -- Cody Ransom was an Arizona Diamondback on Monday, a Milwaukee Brewer on Wednesday and the Brewers' new starting shortstop by Friday night.

Ransom has suddenly become a very important player for Milwaukee, which has already lost Opening Day shortstop Alez Gonzalez to a season-ending knee injury and suffered another blow in Friday's win over the D-backs, when Cesar Izturis strained his left hamstring. He was placed on the 15-day disabled list.

"That's a big pick-up," Brewers right fielder Corey Hart said of Ransom.

The D-backs designated Ransom for assignment on Monday and the Brewers claimed him off waivers on Wednesday, making for some convenient travel. Ransom grew up in suburban Phoenix and still lives in the area, so he'd been at home with his wife and two children.

"It's been pretty relaxing," he said. "I've been at the house. I haven't done anything since Sunday."

Ransom batted .269 for Arizona with four home runs and 13 RBIs in 52 at-bats. He was surprised when they removed him from the roster on Monday.

Of being picked up by the Brewers, Ransom said, "Good. I've got a job. At that point, I was excited to be going somewhere, to be staying in the big leagues and not going back to Triple-A somewhere. We'll see how it goes."

The Brewers optioned Edwin Maysonet back to Triple-A Nashville to clear space for Ransom, then had to recall Maysonet on Friday night after Izturis was injured.

Ransom will make his first Brewers start Saturday against Arizona left-hander Wade Miley.

Brewers mulling options to replace Estrada

PHOENIX -- The Brewers have discussed promoting red-hot Double-A Huntsville right-hander Tyler Thornburg for their starting rotation vacancy but will probably fill that spot with a more advanced arm, assistant general manager Gord Ash said Friday.

The Brewers need a replacement beginning Tuesday for Marco Estrada, who strained his right hamstring in his last start and was placed on the disabled list. Among the options are reliever Manny Parra, a former starting pitcher, or a callup from a list that includes Triple-A Nashville right-handers Wily Peralta and Mike Fiers, and, yes, Thornburg, a 23-year-old who would have to jump two levels.

"I don't think that's at the higher end of the probabilities," Ash said. "You also have a roster to manage."

And the Brewers' 40-man roster is "more than full," Ash said of a roster that's at capacity, plus three players on the 60-day DL.

Manager Ron Roenicke said the team would announce its intent in the next couple of days, though it could go all the way to Tuesday, when the Brewers play the second of four games at Dodger Stadium.

He alluded to a desire to leave Parra in the bullpen, where the left-hander has a 3.70 ERA in 19 appearances this season, with 25 strikeouts versus nine walks.

"I really like what he's doing in the bullpen right now," Roenicke said. "Even if we have someone else start it and we have [Parra] piggyback, I would probably feel better about it, just because I know what he's doing for us so far."

That would seem to put Fiers and Peralta at the front of the line.

"They've had flashes of brilliance," Ash said. "It's just been rare that [they go] innings one through seven or eight, clean. There's always some hiccup."

Fiers provided an example Thursday night against Las Vegas, allowing four first-inning runs on three hits -- including back-to-back homers -- then retiring 19 of the final 20 batters he faced. He is 1-3 with a 4.55 ERA and a team-best 49 strikeouts in 10 starts, and is already in line to start Tuesday.

Peralta, the Brewers' consensus top prospect entering the season, is 1-5 with a 5.62 ERA in nine inconsistent starts for Nashville. He is currently scheduled to pitch Sunday.

Also at Nashville is right-hander Mark Rogers, who is 0-2 with a 5.29 ERA in seven starts. He is also on the 40-man roster.

Down at Huntsville, Thornburg is 6-0 with a 2.28 ERA in 10 starts, with 59 strikeouts and 20 walks in 59 1/3 innings.

"His name has definitely come up," Roenicke said. "I talked to Rick [Kranitz, Milwaukee's pitching coach] today about him a little bit. If [Thornburg] had been with us in Spring Training and been lights out in Spring Training, it makes you feel a little bit better. When he pitched, he was a little nervous, which they should be. Those first times, these guys want to show us something. Nerves play into it a lot."

Estrada hoping for quick stint on DL

PHOENIX -- Brewers right-hander Marco Estrada was told he could miss more than a month with his strained right quadriceps. He's hoping to beat that projection.

"We're hoping for two weeks, hopefully it's less," he said. "I did hear 4-6 weeks. They said that's how long it normally takes. I had a cortisone shot and they told me that could speed up the process."

Estrada suffered a slight tear of his right quadriceps while legging out a two-run double in the first inning of Wednesday's win over the Giants. The Brewers placed him on the 15-day DL on Thursday.

Estrada was able to put weight on his right leg but was barred from physical activity for a few days while the cortisone does its work. Eventually, he hopes to resume throwing to keep his arm in shape while his leg heals.

"I have to do something," Estrada said.

Last call

• Friday marked the five-year anniversary of Brewers left fielder Ryan Braun's Major League debut. He was 1-for-4 with a double, a sacrifice fly and two RBIs at San Diego on May 25, 2007.

In the five years that followe, Braun led the Majors with 1,720 total bases and 395 extra-base hits. He also ranked second in that span with 537 runs scored, third with a .566 slugging percentage and fourth with 173 home runs and 562 RBIs.

• The Brewers activated former first-round Draft pick Jed Bradley from Class A Brevard County's disabled list in time for a Friday night start at Dunedin, Fla. Bradley, the second of Milwaukee's two first-round picks in last year's First-Year Player Draft, had missed time with a groin strain.

• Also in the Minors, the Brewers traded Nashville catcher Paul Phillips to Toronto for cash. It was an easy transition; the Sounds were already in Las Vegas playing Toronto's top affiliate.
