Either way, there's a monumental difference in his last four starts.
Up until his June 14 start against the Giants, the rookie right-hander was 4-1 with a 1.12 ERA. Collmenter has lost his last four starts though, and his ERA has shot up to 3.17 in the process.
"I just think he goes fastball-changeup pretty much, and then when they get the third time around they've been getting on him in his last four starts," Diamondbacks manager Kirk Gibson said. "So he's going to have to figure something out and he's going to have to mix it up a little more. He's going to have to change some patterns."
And Collmenter isn't going to have much room for error against Milwaukee starting pitcher Yovani Gallardo. The Brewers' 25-year-old righty has a 9-5 record this season with a 3.92 ERA.
Even though Gallardo lost his last decision after surrendering three earned runs, he is, at this point, of no greater concern to Brewers manager Ron Roenicke than any other area of the team.
"We have these periods where we just don't play well, in all phases," he said. "I talk about the pitching and the hitting, but it's the defense too. I really feel good about this team, and it surprises me when we go through a long period where we're not playing well."
"We better turn it around and start playing well."
Especially since Collmenter has been working at bettering his stuff.
"I'm still working on it," Collmenter said of his breaking ball. "Find a way to throw it more, I guess, get more comfortable with it and go from there, but continue to develop it so it can be a weapon."
Brewers: Roenicke calls team meeting after lousy loss
Milwaukee manager Ron Roenicke called a team meeting after Tuesday's loss. It was the second team meeting the skipper has called all season.
Roenicke clearly felt the need for a team meeting, though usually, he saves those discussions for the team's pre-series meetings.
"I'm not picking out individuals, because that's not the problem," Roenicke said. "The problem is the whole group. The problem is me and the coaches. We're all together in this thing, and we all need to figure it out."
Roenicke described what the Brewers have been going through as a "battle," but one that's still ongoing.
"I don't see us giving up. I don't see us quitting, even when we get behind in games," Roenicke said. "I still see an offense that's working hard to try to get back in the ballgame."
The Brewers are clearly still very much in contention in the National League Central division, but with a loss on Tuesday, Milwaukee lost consecutive games at home for the first time all season. The Brewers have now lost seven of their last eight games.
Ryan Braun will likely be available Wednesday after missing three consecutive games with a left calf strain. Braun may not start on Wednesday, but Ron Roenicke said he should be available, which means he'll probably have a chance to extend his 22-game hit streak. Braun had a helmet on in the dugout late during Tuesday's game, but didn't get an opportunity to pinch-hit.
Diamondbacks: Team also likes Miller Park
Milwaukee has been the best team at home this season, but the D-backs have played very well at Miller Park as well.
Arizona has won 5 of the last 6 games against the Brewers, and has taken 7 of the last 9 games at Miller Park.
Arizona handed the Brewers their first two-game losing streak at home this season on Tuesday.
Geoff Blum went 0-for-3 at third base in his first rehab appearance at Triple-A Reno on Monday.
The D-backs are 32-19, good for a .627 winning percentage, since May 13. Their 32 wins are second in the Major Leagues behind the Red Sox's 33 wins in that stretch. The Yankees and Phillies each have 31 wins in that span.
The Brewers hold an all-time 49-44 edge against the D-backs. Milwaukee is 19-11 against Arizona since 2007, but is now 0-2 against the Diamondbacks this season.
Arizona and Milwaukee will meet up again after the All-Star Break for a four-game series from July 18-21 in Arizona.
