MILWAUKEE -- Maybe Rickie Weeks' two-hit showing against the Reds on Saturday evening will spark a turnaround at the plate for the second baseman. Or maybe it won't.

Weeks just never reads too much into any individual performances.

"I'm not a big believer in that," Weeks said. "I know that I'm feeling good right now, and I think I can have a pretty good stretch from here on out."

Weeks' 2-for-4 night at the plate prompted Brewers manager Ned Yost to insert him in the starting lineup again for Sunday afternoon's game. Weeks batted leadoff for the second straight game.

Before Saturday, Weeks had collected just one hit in his first 13 at-bats since returning on Aug. 10 from a brief stint at Triple-A Nashville. But the second baseman had ripped apart Triple-A pitching during his stint with the Sounds, batting .455 (10-for-22) with three doubles, a triple and three RBIs in six games.

"Baseball's different -- it's not like any other sport where you can go out there and just try to feel good every day," Weeks said. "In baseball, you're going to have your ups and downs, and you just start feeling better all of a sudden. Sometimes, it's there. Sometimes, it's not."

Since returning to the team, Weeks has shown signs of turning things around at the plate. He drew four walks against the Astros in his first game back and scored the winning run in a 5-4 victory.

But Weeks once again refused to read too much into his walks.

"If your swing's affected, you don't see the ball, and if you don't see the ball, your swing's affected," Weeks said. "It goes hand-in-hand, so you really can't say it's one or the other. All I can say is that I'm feeling pretty good right now."

The second baseman has suffered from discomfort in his wrist all season after he tore a tendon sheath in his right wrist late last season and underwent surgery during the offseason to repair it.

"It's alright," he said. "I really don't want to talk about it, to tell you the truth. I just want to get it out of my mind and just go out there and play ball."

Still not there: Corey Koskie's visit to Miller Park this past weekend has been a bittersweet affair.

While it gave him the chance to catch up with his old Brewers comrades, the trip also left him feeling frustrated that he is missing out on their pennant race.

"I feel like I've got a lot to offer these guys," Koskie said. "But I just can't do it. Any baseball -- watching baseball at malls, stadiums, arenas -- they all make me sick. I get headaches and that kind of stuff, so I can't even go to malls, grocery stores, all that."

Koskie said he is nowhere close to returning to action. His doctors had placed him on a schedule to try to increase his tolerance to physical activity, but he has been stuck on 10 minutes on the treadmill and a maximum heart rate of 130 beats per minute for a few months now.

"That's just part of concussion syndrome and brain injuries," Koskie said. "It's just on its own timetable."

The lingering effects of Koskie's injury, which he suffered in a game against the Reds on July 5, 2006, when he fell backward while chasing a popup, have left him wondering if his career is over.

But at this point, Koskie worries more about getting his life back on track, whether it's playing with his three sons or simply just driving around town -- things he still has trouble doing for too long without feeling sick.

"That's the toughest part, because that's life," Koskie said. "My baseball career, no matter how good and long it is, is going to be over at some point. But you still want to be able to continue to look forward to living your life after that without having to shut it down."

Sheets update: Yost said staff ace Ben Sheets will pitch a simulated game sometime between 1:30-2 p.m. Monday at Chase Field, before the Brewers take on the Diamondbacks later in the day.

Sheets will be facing hitters from the Brewers' Minor League camp at Maryvale Baseball Park.

The Brewers originally had planned on sending Sheets on a Minor League rehabilitation start after his simulated game, barring any setbacks. Yost acknowledged Sheets possibly could skip that step and make his return to the team in time for its weekend series against the Giants, but the skipper would not commit to any concrete plans.

"We'll just get him back first," Yost said. "There's a lot we have to see before we make that judgment."

Pitch counts: Claudio Vargas tossed a season-high 115 pitches in Saturday night's win against the Reds, marking the fourth straight game a Brewers starter had reached the 100-pitch mark since they designated reliever Chris Spurling for assignment Wednesday.

The Brewers' decision to recall outfielder Gabe Gross to take Spurling's spot on the roster left them with 12 pitchers, after they had carried 13 pitchers for two weeks prior to that. Having one fewer arm in the bullpen means Yost has had to give his starters more leeway to pitch deeper in games.

"I don't have that luxury I had of one extra guy, so I'm kind of working on a budget, so to speak," Yost said. "You get [the starters] a little bit farther along until September, and then we'll have the luxury of having some more arms."

Yost said he doesn't worry about his starters topping the 100-pitch mark, as long as they don't have to endure too many big innings during their outings.

"It's not the pitch count," Yost said. "It's the big-pitch innings, where you pitch 30. Or the 35-pitch innings. Those are the ones that wear you out. It's not the 110 pitches."

Happy birthday: Three different Brewers celebrated their birthdays Sunday. Yost turned 53, while starter Chris Capuano became a 29-year-old and shortstop J.J. Hardy turned 25.

Last call: Hall of Famer Fergie Jenkins made an appearance at Miller Park on Sunday afternoon and took part in an autograph session during the game.

On deck: The Brewers begin a nine-game road trip with Monday evening's contest against the National League West-leading Diamondbacks at Chase Field. Yovani Gallardo (4-3, 4.84 ERA) takes the hill for Milwaukee against former Brewer Doug Davis (10-10, 3.92). Milwaukee has an NL-worst 23-36 road record.
