The middle game of this weekend's series between the Brewers and Phillies features starting pitchers still seeking to prove something.
Milwuakee's 24-year-old right-hander Wily Peralta and Philadelphia's 26-year-old righty Tyler Cloyd began their careers with success, but have each run into trouble this season.
Peralta, who switched spots in the rotation with Sunday's starter Mike Fiers, has regressed from the promising and confident young pitcher he came up as in 2012.
"We do have to get him going," Brewers manager Ron Roenicke said. "Hopefully we've gone through the growing pains of young guys, trying to get comfortable and confident and all that. But, yeah, he needs to get throwing well."
Peralta started this season 3-2, but lost five of six starts in May, including his last four. Peralta's ERA has ballooned to 6.35, and he has failed to pitch past the fifth inning in four of his past six starts.
Roenicke knows the importance of returning Peralta to form within a pitching rotation that is strugging around him.
"He came up last year and was a very confident pitcher, and we saw what kind of job he can do when he's feeling that way," Roenicke said. "He has a good game or a few good innings, and all of a sudden, he gets confident. Some guys are naturally more confident, and some guys need to have success to be confident."
Cloyd will make his fourth Major League start since replacing Roy Halladay in the Phillies' rotation, and it could be pivotal for his immediate future.
In his first two starts, Cloyd allowed just four runs over a combined 13 1/3 innings. But on Monday against the Red Sox, Cloyd was shelled for six runs on nine hits in 2 1/3 innings.
If Cloyd continues to falter, one option for the Phillies would be veteran right-hander Carlos Zambrano, who is currently building arm strength at Class A Clearwater.
Phillies: Offense scuffling
Peralta will face a Phillies offense struggling to score runs. Philadelphia has scored three or fewer runs in 31 of their first 55 games and that's starting to wear on manager Charlie Manuel.
"I don't wonder what's going on," Manuel said before Friday's series opener. "I see it. I don't have to wonder. I see that we don't get enough guys on base to score runs. And I see that we don't hit consistently enough.
"Let me tell you something, we're trying to fix it. We try every day to fix it."
The Phillies have scored three or fewer runs in nine of their last 13 games.
• The Phillies released 14-year veteran Chad Durbin, on Friday one day after he gave up three runs on four hits in one inning against the Red Sox.
To fill his spot on the 25-man roster, the Phillies recalled left-handed pitcher Joe Savery from Triple-A Lehigh Valley.
• The Phillies fell to three games under .500 with their loss to the Brewers on Friday. They haven't been at the even-water mark since they were 6-6 through April 14, but the schedule allows them a chance to get back there.
They finish up a three-game set against the Brewers, followed by another with the Marlins at Citizens Bank Park. Then they go to Milwaukee for four, followed by three at Minnesota.
Brewers: Peralta, Fiers swap spots in rotation
The Brewers swapped their weekend starters because they decided to give Fiers extra rest.
Fiers was up throwing in the bullpen on Thursday, but did not make an appearance. The Brewers then opted to give him another day and pitch him on regular rest, after his three-inning relief stint in the 14-inning game against the Twins on Tuesday.
• Friday's series-opening win over the Phillies snapped the Brewers' season-long six game losing streak and helped them avoid tying the club record for losses in a month. The Brewers matched a franchise-low winning percentage in a month with a 6-23 record (.207).
• The Brewers have won just one of eight series away from Miller Park this year, for an 8-17 mark on the road.
•The Phillies are 35-16 all-time when hosting Milwaukee, including a 22-11 mark at Citizens Bank Park.
