Correia has started four games so far this month, alternating unimpressive ones with ones where he's been knocked around like he was a 17-year old pitching to professionals. It would be good to see him turn things around today and get himself under control a little bit, particularly after the upheaval in the rotation this week and the way Mike Pelfrey is being pushed by Kyle Gibson.
Facing off against Aoki, Segura, Braun, Ramirez, and Gomez as the Brewers one to five batters won't make it an easy task. Current Brewers have also combined to hit .288/.335/.481 against him in 160 at-bats, although Corey Hart won't be an issue today. Gomez, Aoki, and Segura have just 13 at-bats against him though, so Milwaukee's level of comfort in seeing Correia might not be as imposing as it looks.
In ten starts this season, Peralta has actually put together five quality starts. Of course, a "quality start" is at least six innings and three earned runs or less, so that's quite subjective and, as you can see by his line, he hasn't really been all that good this year.
Peralta has never pitched against the Twins and no Twin has seen him as a member of another club, so the Twins would probably be well served to be patient today. He's exclusively a three-pitch guy this year: fastball, slider, changeup.
Right-handed hitters will see Peralta's mid-90s fastball in and out, although at times he'll consistently catch far too much of the plate. His sliders are always down and away, and will drop out of the zone just as often as he'll nip the corner. The changeup is generally at the knees, but his occasional lack of command means the changeup is left up in the zone and can give hitters big opportunities to take advantage of mistakes.
Against lefties Peralta isn't nearly as confident coming inside, which works pretty well for Joe Mauer and Justin Morneau, who are both pretty happy going the other way. The slider is used more as a back door option here, and if he does throw it on the inner half it almost always drops out of the zone. The changeup, like the fastball, is consistently down and away.
