Patrick Corbin has a good recent history against the Giants and has shown recent signs of regaining his All-Star status of a couple of years ago. But backing the Diamondbacks is mainly a fade on Jake Peavy.

Peavy was a great pitcher when he was with San Diego. But that was seven years ago. Now he shouldn't be in a major league starting rotation. He's given up four or more runs in five of seven starts with an 8.47 ERA. That ERA shoots up to 14.25 when you just go with his three road starts - all losses. Since 2014, Peavy is 2-16 with a 5.32 ERA before the All-Star break.

Peavy has a 7.20 lifetime ERA against Arizona in three starts. The Giants are down setup man Sergio Romo and have bullpen fatigue issues making it worse for Peavy.

Corbin has won his last two starts versus the Giants holding them scoreless in 13 innings. He's also pitching with an extra day of rest. Arizona is 6-1 the past seven times Corbin has pitched on five day's rest.
