Tonight's Matchup: Milwaukee (Greinke) at Arizona (Miley)

Coming into this season, Wade Miley (4-1, 2.12) was the Diamondbacks' thirteenth best prospect according to John Sickels. Miley curently has a 2.12 ERA and 3.28 FIP. Since being made a starter on April 23, he has made six starts with a 1.91 ERA and .630 opponent OPS. Sort of makes you wonder what Tyler Skaggs and Trevor Bauer--the Diamondbacks' top two prospects and two of the top pitching prospects in the game--could do.

Miley has been excellent despite low strikeout numbers. He has just a 5.73 career K/9 in the majors and never really struck out many hitters in the minors. There were a couple stops where his K/9 jumped, but nothing that appeared sustainable. Throughout much of his minor league career, he also had a high walk rate, with a BB/9 sitting in the mid-3.00s to 4.00s. This season, he has knocked those numbers down to just a 2.73 BB/9, which is surely helping his overall numbers. Also aiding him is a 0.39 HR/9, which is bound to come up sooner or later.

In six starts, Miley has not allowed an earned run in three of them. He would have five quality starts, but he missed out on one by one out. His only other non-quality start came against the Mets when he allowed four earned runs in six innings. He has yet to walk more than two hitters in a start. His first two starts were especially impressive. Against the Phillies and Marlins he threw a combined 12.1 innings and allowed just three hits overall.

Miley relies heavily on his fastballs. He throws a 92 MPH four seamer 48% of the time and a 91 MPH two seamer 25% of the time. He'll also throw an 81 MPH changeup (14%) and an 80 MPH curveball (14%).

Unsurprisingly, Miley has never faced a Brewers hitter. Uh-oh.

Zack Greinke (5-1, 2.70) has been good Zack Greinke all year. A 2.70 ERA, 1.76 FIP, 2.37 xFIP, 9.37 K/9, 1.91 BB/9, and 0.16 HR/9 should make him a Cy Young contender, easily. Hell, it should maybe make him the Cy Young frontrunner. He even has a 5-1 record! Greinke is having an absolutely phenomenal season and is a bright spot in an otherwise drab start to 2012.

His numbers would look even better if not for his second start of the year against the Cubs when he gave up eight runs in 3.2 innings. That was one of only two non-quality starts. The other was due to him only pitching 5.1 innings, as he allowed just three runs to the Giants. He hasn't allowed more than two earned runs in any other start.

Zack Greinke might very well be the best pitcher in the major leagues when he keeps it all together. He did in 2009. He might be doing it again.

Greinke has faced six current Diamondbacks at least ten times. Here is how they have fared:
