Blister better, Nelson slated to start on Tuesday

ST. LOUIS -- Scratched from Saturday's start because of a blister on his right index finger, right-hander Jimmy Nelson won't have to wait long to get back on the mound, as the team believes he'll be ready to pitch against the Giants on Tuesday at Miller Park.

The timing of Nelson's minor setback worked out for the Brewers. It came during a three-game series sandwiched between a pair of off-days, allowing for some easy rotation shuffling, and it also gave the Brewers a way to split up Nelson and Wily Peralta, something manager Ron Roenicke and pitching coach Rick Kranitz were already mulling.

Both are right-handers with similar stuff, including a power sinker.

"When this came along, it just allowed us to do this real cleanly," Roenicke said.

Nelson developed the blister during his Sunday start against the Mets, a 2-0 loss at Miller Park. The skin tore away during a long-toss session earlier this week in St. Petersburg, prompting the Brewers to make some changes. Kyle Lohse and Matt Garza each moved up a day but were still set to work on regular rest.

Nelson will attempt a light bullpen session on Sunday to confirm his availability for Tuesday. If he does have a setback, Yovani Gallardo would move up a day.

Peralta quietly taking his place among elite

ST. LOUIS -- Considering that Wily Peralta wasn't aware on Saturday that he is tied with a trio of Cy Young Award winners for the Major League lead in victories, he was certainly not aware how rare finishing the season at the top of the leaderboard would be in Brewers history.

Only once in the first 44 seasons of Brewers baseball has one of their own led his league in victories. That was in the strike-shortened season of 1981, when Pete Vuckovich won 14 to tie Baltimore's Dennis Martinez, Oakland's Steve McCatty and Detroit's Jack Morris atop the American League. Cincinnati's Tom Seaver led the National League that season, also with 14.

It would take a strong finish for both Peralta and his team, but the second-year right-hander has at least an opportunity to match Vuckovich. He allowed two runs in 6 2/3 innings of Friday's 7-4 win over the Cardinals, giving him 13 victories in his first 22 starts.

The other pitchers with 13 wins are the Dodgers' Clayton Kershaw, the Cardinals' Adam Wainwright and the Tigers' Max Scherzer.

"Whew!" Peralta said. "I didn't know. That's a few Cy Young guys. That's what I've been working for. I've improved in pretty much everything. My command has been unbelievable this year, and that's something I was struggling with last year. I was working behind the counts on hitters. I said in spring that was one of my goals -- attack hitters."

Peralta has a 3.52 ERA, and he has gone 4-0 with a 1.71 ERA in the four starts he's made since a nine-run blowup against the Phillies on July 8.

The league is taking note.

"I think last year he started to figure things out, [in the] second half especially," said Wainwright, who was on the losing end on Friday night. "He's just got such a great fastball sitting at 96 [mph], with some very good movement on it. He's obviously stepped his game up."

The Brewers tend to keep their starters in order through off-days, so Peralta has about 10 starts remaining. He could be the fourth 20-game winner in franchise history, a number not reached since Teddy Higuera went 20-11 (including 15 complete games) in 1986.

Peralta is also on track to becoming just the eighth 18-game winner in Brewers history. Chris Capuano (18-12 in 2005) is the only Milwaukee pitcher to win that many since 1987.

Although it's rare for a Brewers pitcher to lead his league in wins, it's not unprecedented in Milwaukee's history. Hall of Famer Warren Spahn either led the NL or tied for the lead six times with the Milwaukee Braves from 1953 to 1961, including a '59 season in which he and teammate Lew Burdette matched Sam Jones of the Giants with 21 wins.

Last call

• Second baseman Scooter Gennett was back in the lineup on Saturday after enduring a scare the day before. He was struck on the left index finger during pregame bunting drills and worried that it was broken, but an X-ray alleviated his concern.

"It caught me on a weird angle," Gennett said. "It didn't smash it, it caught it on a different angle. I was kind of worried, but once I saw the X-ray, I was fine."
