Platoon ends, Bush stays in the rotation

Milwaukee (62-51) at Cincinnati (52-61), Tuesday, 6:10 p.m. CT

CINCINNATI -- Brewers manager Ned Yost expressed a level of disappointment on Monday that his unconventional fifth-starter platoon did not work as planned.

Dave Bush will lead the Battlin' Brewers against the Reds on Tuesday night in the official end of the Brewers' timesharing agreement between Bush and Seth McClung, who since the All-Star break had been starting road games while Bush started at home. Yost installed the platoon after the Brewers acquired starter CC Sabathia on July 7.

Neither Bush nor McClung flourished in the setup despite earlier statistical evidence that McClung was slightly more effective in road games and Bush was much more effective at home. Both pitchers said the right things about wanting to help the team, but also made it clear they would rather be a full-time member of the starting rotation.

"I thought that we could have handled it that way if they both could handle it, mentally," Yost said. "Neither one of them felt comfortable in that role, so then you make a tough decision. Somebody has to go to the 'pen and somebody stays in the starting rotation. It's as simple as that."

Asked if today's player was too hung up on defined roles, Yost said, "A little bit. The whole thing is, their role is to do whatever I ask them to do. That's their role. Sometimes you have to define it out a little farther than that, but it doesn't mean you write it in stone every single day."

Bush is 1-6 with a 6.94 ERA in his nine appearances on the road, but stuck in the rotation over McClung, who has a 6.32 ERA in five appearances since the All-Star break.

After he was informed of the decision on Saturday, McClung admitted he was "disappointed." Yost was asked if he had a reaction to that reaction.

"It's a 25-man team and every man is asked to do a job. So disappointment doesn't really play into it," Yost said. "You do your job, you help the team win. That's my reaction to it. ... Right now, we're in the last two months of the season. We're here together."

It did not appear so on Monday, when first baseman Prince Fielder twice shoved pitcher Manny Parra in the Brewers dugout. Yost was upset that cameras caught the scuffle and refused to go into detail on the subject, but he did hint that discipline could be in order.

It was the Brewers' second dugout incident in about a year. Last Aug. 2, Yost argued with infielder Tony Graffanino and catcher Johnny Estrada during a game against the Mets at Miller Park.

Pitching matchup
MIL: RHP Dave Bush (5-9, 4.69 ERA)
Bush was pleased to return to the rotation full-time after splitting starts with McClung. "I couldn't replicate the work on the sides," said Bush, who had 15 days' rest between starts after the platoon took effect in mid July. "I was working more on mechanics and keeping my endurance up, not focusing on improving the starts. It'll be good to do a regular session for now."

CIN: RHP Edinson Volquez (13-4, 2.71 ERA)
Volquez pitched 6 1/3 innings and mostly appeared to shed his two-game slump with a 9-5 win over the Astros Wednesday. The right-hander encountered little trouble until a four-run seventh inning that was extended by two errors by shortstop Jeff Keppinger. The mistakes culminated in a three-run homer by Ty Wigginton. Only one of the five runs Volquez allowed was earned on six hits with one walk and five strikeouts. Following two sub-par starts coming out of the All-Star break, Volquez watched some video and made mechanical corrections.

Center fielder Mike Cameron hit a solo home run on Monday, but has a .315 on-base percentage, 26 points below his career average. "He is consistent in the outfield," Yost said. "He saves us a ton of runs out there. It is what it is. He gives his best effort, he goes out and saves us runs in the outfield, hits home runs, runs the bases great, plays hard every time he gets in there. To be honest with you, it is what it is. It's not a concern." ... Rickie Weeks, who was 1-for-14 (.071) in his career against Reds starter Bronson Arroyo, got the nod at second base on Monday over Ray Durham, who was 1-for-10 (.100). When the numbers are not clearly in favor of one player or the other, Yost said he would tend to start Weeks. ... Fielder has a hit in eight straight games. He's hitting .393 (11-for-28) during the streak.
