Wily Peralta has been one of baseball's best pitchers this month.
It's been a welcome departure from his struggles for the Milwaukee Brewers earlier this season, which began with a mediocre performance against the Colorado Rockies.
Now, Peralta gets a second chance against the Rockies as he takes the mound at Coors Field on Friday night.
Peralta (7-9, 4.30 ERA) posted a 5.58 ERA through his first 17 starts, including a 7-3 loss to Colorado on April 3 in which he gave up four runs in 5 1-3 innings.
But the right-hander has reversed his fortunes of late and has given up one earned run in 29 1-3 innings over four July starts for a major league-best 0.31 ERA.
Peralta has also thrown at least seven innings in each of his last three outings after doing so just twice in his previous 18. His strikeout totals of eight and seven in his last two games are his highest this year.
"Wily, he's throwing strikes is the biggest thing," manager Ron Roenicke told the team's official website after Peralta gave up two hits over eight innings in a 1-0 win over Miami on Sunday. "Today's probably the best I've seen his slider, as far as he could throw it for a strike when he wanted to and he could bury it in the dirt when he wanted to and get some strikeouts."
He'll face a Colorado (49-54) lineup that could be without Carlos Gonzalez. The All-Star outfielder, tied for the NL lead with 26 home runs, is day to day after leaving in the fourth inning of the Rockies' 5-3 loss to Miami on Thursday. He aggravated a sprain on his right middle finger, an injury he has been bothered by since sustaining it in a July 7 at-bat.
The Brewers (42-59) fell to 1-3 since Ryan Braun's suspension, losing 10-8 to San Diego on Thursday though they trailed 6-0 at one point. Roenicke's search for a No. 3 hitter in Braun's absence for the rest of the season will likely continue as Jean Segura was 0 for 5 and is 1 for 17 while batting in the third spot each of the last four games. Carlos Gomez is 7 for 9 over his last two contests and hit his 16th homer Thursday.
He'll look to stay hot against scheduled starter Tyler Chatwood (6-3, 2.48), who has been solid after one of the roughest outings of his career. The right-hander is 2-1 with a 1.74 ERA in three starts since allowing six runs and 11 hits over five innings of a 10-8 loss to the Dodgers on July 3.
Wilin Rosario has hit safely in all eight of his games versus Milwaukee, going 12 for 28 (.429) with three homers and seven RBIs. Troy Tulowitzki is hitting .200 with 12 strikeouts in 10 games since returning from a fractured rib, but is batting .395 in 32 career contests against the Brewers with 10 home runs and 28 RBIs.
Rickie Weeks has also been cold, going 2 for 32 (.063) over his last 10 games but is 11 for 25 in his last six games versus Colorado with two home runs and two doubles.
The Rockies have won eight of the last 10 meetings after taking two of three in Milwaukee during the teams' season-opening series.
