Patrick Corbin moved to 7-0 by pitching a three-hitter and striking out 10 as the Diamondbacks topped the Rockies 5-1 on Monday. Corbin's April could have been written off as something of a fluke after he went 3-0 with a 1.91 ERA. However, he's now 4-0 with a 0.92 ERA in May. It's a pretty amazing transformation for a guy who went 6-8 with a 4.54 ERA and 14 homers allowed in 107 innings last year.
