Izturis not sweating tough start

GLENDALE, Ariz. -- Veteran shortstop Cesar Izturis is regarded as a slick defender, though you wouldn't know it from his first few games in a Brewers uniform.

Izturis was charged with three errors in his first three games, including two in Tuesday's 6-0 loss to the A's that led to four earned runs. He also committed an error Monday against the Giants and was spared another error when first baseman Mat Gamel scooped a bounced throw.

It's a surprising start for a player who could open the season as Milwaukee's backup shortstop.

"From now on, it's going to be better," Izturis said. "Hopefully, all the errors stay here instead of going to Milwaukee."

Brewers manager Ron Roenicke said Izturis "wasn't very happy about what happened [Tuesday] or the day before." Roenicke compared it to a good hitter going through a slump at the plate.

"As good as he is defensively, I'm sure he's a little shocked at him not playing well," Roenicke said.

Izturis, a non-roster invitee to Brewers camp, will play a lot of second base this spring, because it's the position at which he could use the most work, according to Roenicke. Izturis has mostly been a shortstop in the Major Leagues and is also comfortable at third base.

Hart says surgery was right call

GLENDALE, Ariz. -- Corey Hart had the photographic proof in his locker. He made a wise decision by opting for knee surgery.

"They said if I would have kept playing, I wouldn't have made it a month," Hart said.

Hart moved around Maryvale Baseball Park on crutches Wednesday, a day after undergoing arthroscopic surgery to repair torn cartilage in his right knee. He brought images of the surgery to the ballpark, showing three significant tears in his meniscus, the half-moon-shaped strip of cartilage that lubricates the knee.

Only one of those tears had been clearly visible on the MRI scan that preceded surgery, leaving Hart a choice. He could have surgery now and risk missing Opening Day or delay surgery until the fall and risk a more significant injury.

Hart chose the former.

"Other people said, 'Well, Rickie [Weeks] played through it, [Craig] Counsell played through it,' but those were all minor tears," Hart said. "Not like mine. Dr. [William] Raasch told me all three of my tears were bigger than Rickie's one."

Had he continued playing and worsened the tears, Hart would have faced a more invasive surgery and three to four months of rehabilitation. Instead, he will need three to four weeks to recover from the scope.

Hart will spent the rest of this week recovering from surgery and expects to begin exercise next week.

The surgery result qualified as good news for the Brewers.

"He's happy about it," manager Ron Roenicke said. "If he didn't have this now, it looked like he wouldn't have been able to get through the season on it. It's a good thing they went in."

Estrada latest Brewers starter off to fast start

GLENDALE, Ariz. -- The Brewers' starting pitchers are off to a promising Spring Training start.

Right-hander Marco Estrada on Wednesday became the fifth Brewers starter -- including Zack Greinke, who piggybacked with Randy Wolf in Milwaukee's spring opener -- to breeze through his Cactus League debut. Wolf, Greinke, Chris Narveson, Yovani Gallardo and Estrada have each worked two scoreless innings in the first turn through the rotation.

Estrada didn't know a streak was at stake when he took the mound against the White Sox.

"Thank God, I didn't give any runs up then," Estrada said. "I had no idea."

Estrada is stretching out as a starter in case he's needed to start the season. Last year, he filled in for an injured Greinke. This season, the Brewers are being cautious with Shaun Marcum's stiff shoulder.

Assuming Marcum gets on track, then Estrada could begin the season in the bullpen.

"It's easier to go from five innings to one than from one to five," he said.

A future Brewers starter was also impressive in Wednesday's 10-6 win over the White Sox. Taylor Jungmann, one of Milwaukee's two first-round picks in last year's Draft, pitched two innings without an earned run. Chicago scored an unearned run in Jungmann's second inning of work after two walks and an error.

Last call

Rickie Weeks was the Brewers' designated hitter for the third straight game Wednesday, still resting a sore throwing shoulder. Roenicke said he hopes Weeks will be able to play second base on Thursday. ... Left-hander Zach Braddock did not make his scheduled appearance in Tuesday's game against Oakland because of a blister. Braddock had previously been set back in camp by an illness. ... Right-hander Mark Rogers' left hamstring strain has recovered to the point where he'll pitch in a game Friday or Saturday. ... Roenicke has liked what he's seen so far from Norichika Aoki, who started Wednesday in center field. Aoki is more aggressive at the plate than Roenicke expected, but he has the sort of short swing and contact approach that Brewers coaches believe will serve him well in a bench role.
