The Brewers' starting rotation has been a bit of a puzzle for manager Ron Roenicke this season.
With members of his Opening Day pitching staff frequently going on and off the disabled list due to various injuries, Roenicke has started 11 different pitchers this season. Yovani Gallardo landed on the disabled list on Wednesday, and Tom Gorzelanny's next start is in question after he was hit in the elbow by a line drive on Friday night.
Roenicke hasn't seen anything like it.
"There's a lot of things I haven't seen this year," he said.
Sunday's starter, Kyle Lohse, has been one of the lone constants. While Wily Peralta has shown sporadic moments of brilliance and Marco Estrada has battled a hamstring injury, Lohse has been consistently solid over the past two months. Since June 1, Lohse is 6-1 with a 2.29 ERA. In his past three starts, he's allowed one earned run in 19 innings.
"He's done what we hoped he would do," Roenicke said. "He's done his job. We haven't supported him, which is too bad, because the record with the way he's pitched should be better."
Taylor Jordan will make one of his last starts of the season on Sunday as the Nationals look to complete a much-needed sweep. Jordan is on an innings limit after undergoing Tommy John surgery in September 2011, and while the Nationals have not formally released the details of that limit, the right-hander likely has two or three starts remaining before he will be shut down.
Jordan is fresh off his first Major League win and has shown consistent improvement over each of his six starts. He is 1-3, but has a 3.31 ERA and allowed just one earned run on five hits in his previous start, against the Mets.
"For a little bit, I was wondering: 'Am I going to go 0-4, 0-5? Am I helping the team?'" said Jordan after his last start. "I'm very happy that I got the win, because it means I'm helping the team."
Nationals: Detwiler might not return this season
• Ross Detwiler has dealt with a variety of back issues over the past three months, and Nationals manager Davey Johnson said Saturday that the left-hander might not return this season.
Detwiler, who has been on the disabled list since July 7 with a back strain, will rest two more weeks before resuming baseball-related activities. Barring any setbacks, he still would not return to the Nationals until September.
"We'll try to bring him back before the year is over to make sure he is healthy and nothing further has to be done," Johnson said. "He would have to go through like you go through Spring Training in order to come back. I think we will try to bring him back by the end of the year to see if he is going to be fine."
If Detwiler cannot return by the end of the year, long reliever Ross Ohlendorf would most likely assume the fifth spot in the rotation.
• With his second straight win on Saturday night, Dan Haren improved to 2-2 with a 2.40 ERA since spending time on the disabled list with right shoulder inflammation in June. In 15 starts before his DL stint, he was 4-9 with a 6.15 ERA, which was among the highest in the Majors.
Brewers: Roenicke plans to platoon at second base
• Roenicke said Saturday that Rickie Weeks and Scooter Gennett will both see playing time at second base while Gennett is on the team.
Gennett joined the Brewers as the extra man for Tuesday's doubleheader against the Cubs and remained in Milwaukee when Gallardo was placed on the disabled list the following day. Gennett made his Major League debut in June and platooned with Weeks for most of the month before being optioned back to Triple-A Nashville on June 26.
Roenicke said that he will play Gennett, a left-handed hitter, and Weeks, a right-hander, depending on the opposing pitcher that day.
"What we're going to do is just match up," Roenicke said. "So, we're going to do that for a while, and then we'll see what happens."
• All-Star shortstop Jean Segura (12 home runs, 31 stolen bases) and outfielder Carlos Gomez (17/29) are two of the three players in the Major Leagues with more than 10 home runs and 25 stolen bases this season. Pittsburgh's Starling Marte is the other. Gomez and Segura's 60 combined stolen bases are also the most among any two Major League teammates.
• Lohse is 5-2 in 13 career starts against the Nationals, but they have tagged him for four earned runs or more in three of their past four meetings.
• The Brewers are the only team in the Major Leagues this season without a loss when leading after eight innings (38-0).
