Since getting roughed up in his second start of the season, the Milwaukee Brewers' Zack Greinke has been nearly untouchable over the last month-plus.

Rookie Wade Miley has also proved plenty formidable since transitioning to the Arizona Diamondbacks' rotation.

In what sets up as a low-scoring affair, Greinke takes the hill opposite Miley as the Brewers and Diamondbacks continue a three-game set Saturday night at Chase Field.

Greinke (5-1, 2.70 ERA), who was tagged for a season-worst eight runs in 3 2/3 innings of an 8-0 loss April 12 at Wrigley Field, has since gone 4-0 while giving up a combined nine earned over his last seven outings spanning 46 frames. The 2009 AL Cy Young winner has struck out 47 over that stretch and limited opponents to a .225 average.

Greinke has been especially dominant in his last three starts, going 2-0 with a 0.42 ERA while fanning 24 and walking two in 21 2/3 innings. The right-hander gave up a run and five hits over 6 2/3 innings Sunday in a 16-4 win over Minnesota.

"He's nasty, though. Isn't he?" catcher Jonathan Lucroy said. "He's a lot of fun to catch, working his magic out there. Whenever this guy locates down and away, painting and with velocity and bite on his slider, mixing the slow curve ball, the changeup. This guy won a Cy Young, and there's a reason why."

Greinke's 6.12 ERA over four regular-season starts against the Diamondbacks (20-26) is inflated due to giving up career worsts of 11 runs and 15 hits in 4 1/3 innings of a 12-11, 10-inning road loss June 10, 2005, while with Kansas City. He's 0-2 with a 2.61 ERA in the other three outings.

Greinke, though, wasn't very sharp in Game 2 of last season's NL division series against Arizona, yielding four runs on three homers in five innings.

Miley (5-1, 2.14), meanwhile, has been garnering some well-deserved attention thanks to his continued success. The left-hander, who opened the season in the Diamondbacks' bullpen, improved to 4-1 with a 1.91 ERA over six starts Sunday in a 2-0 road win over the Royals.

Miley threw seven innings of six-hit ball, walking two and striking out three in matching the longest outing of his career.

"Miley was that good," Royals manager Ned Yost said. "We've watched video on him. He was exactly what we thought he'd be. He's got really good stuff, commands the ball down and kind of throws across his body, has a very quick arm and is tough to pick up. He's got a real good changeup, a nice cutter. He was tough on us."

Miley, who's never faced Milwaukee (19-26), will look to help Arizona regroup from Friday's 7-1 loss -- its 15th in 19 home games.

The Diamondbacks went 0 for 6 with runners in scoring position and couldn't get much going against Yovani Gallardo, who threw 7 1/3 sharp innings.

Ryan Braun, Corey Hart and Rickie Weeks, meanwhile, hit their 13th, 10th and fifth homers of the season, respectively, for the Brewers. Despite Friday's win, Milwaukee has dropped 13 of 18 as the visiting team.

The Brewers placed shortstop Cesar Izturis on the 15-day disabled list with a pulled left hamstring suffered Friday. Milwaukee, which already lost Alex Gonzalez to a torn ACL, recalled shortstop Edwin Maysonette from Triple-A Nashville.

Arizona's Miguel Montero is uncertain to be available after missing his third straight game Friday with a strained groin. A person with knowledge of the situation said Montero has agreed to a five-year, $60 million extension.
