PHOENIX -- Brewers manager Ken Macha said Thursday that he had virtually set the club's 25-man roster and that Chris Narveson and Manny Parra have been told they would start the season in the bullpen.

The two left-handers had been vying all spring for the last two spots in the starting rotation. The No. 4 slot went to David Bush and the No. 5 starter is still to be determined. The latter won't be needed until April 14 or 15 against the Cubs at Wrigley Field.

Macha said the roster is set barring any other acquisitions made by general manager Doug Melvin before the season begins Monday against the Rockies at Miller Park with a 1:10 p.m. CT game.

"Speaking to Doug this morning, he always has an eye out to improving the club in various areas," Macha said. "He has a tendency to stay with guys who have been here throughout camp because you know what you've got. That is, unless it's an upgrade. With that being said, he's still checking out some things."

The Brewers were set to break camp after Thursday's game against the D-backs at Maryvale Baseball Park and play exhibition games against the Tigers on Friday night and Saturday in Milwaukee. Jeff Suppan, another candidate for that fifth slot, is starting the season on the 15-day disabled list because of a stiff neck.

The Brewers will have 12 pitchers on their Opening Day roster and will have to make a roster move when Suppan is activated. The Brewers owe the veteran right-hander $12.5 million this season.

Macha takes credit for Wolf jinx

PHOENIX -- Before Thursday's 11-3 loss to the D-backs, Brewers manager Ken Macha noted that Randy Wolf was the only one of his four set starters not to have a bad outing this spring. Think again.

"I blame myself on this one, 100 percent," said Macha, who took the responsibility for jinxing Wolf, who had a 1.13 ERA and hadn't allowed a homer or a walk this spring coming into the game. Well, Wolf still hasn't allowed a walk.

Wolf was crushed for four homers, five runs on seven hits with three strikeouts in Milwaukee's Arizona-closing defeat. Wolf claimed that three of the homers came on the six changeups he threw. The first two were hit back-to-back in the first inning by Justin Upton and Mark Reynolds.

"It's good to get it out of the way," said Wolf about the bad outing. "I'd be concerned if I left Spring Training with great numbers, you don't want that. If any day was the day to leave it all out there, this one was it."

The veteran left-hander, who is slated to start Tuesday night at home against the Rockies, finished the spring with a 3.15 ERA, still respectable.

Macha undecided on batting order

PHOENIX -- Brewers manager Ken Macha has yet to decide who's going to be his No. 2 or No. 5 hitters. The choices for the second spot are center fielder Carlos Gomez or shortstop Alcides Escobar. No. 5 could either be Jim Edmonds or Casey McGehee.

"The lineup kind of forms itself as the season goes on," Macha said. "I want to be able to utilize Gomez's speed [at the top of the lineup]. Let's see how it shakes out."

McGehee has had a tough spring and entered Thursday hitting .172 (10-for-58) with no homers and four RBIs. Edmonds, making a comeback after sitting out the entire 2009 season, was hitting .273 (12-for-44) with two homers and 12 RBIs.

Macha didn't start Edmonds on Thursday because of a sore hamstring. He returned to the club after missing a few days for personal reasons.

Corey Hart also continued to struggle at .127 (7-for-55) with two homers and five RBIs.
