The Phillies have some young talent that is reaching maturity. It's one reason they are a surprising six games above .500. Another reason for their above average showing is Jake Arrieta is pitching as well as he did when he won the Cy Young Award in 2015.

Arrieta isn't getting as many strikeouts as he did three years ago, but he has the highest ground ball rate in the majors this season. Arrieta has permitted just three earned runs in his last five starts spanning 30 innings. He hasn't allowed an earned run during his past two starts spanning 13 2/3 innings.

The Giants are a below .500 team. They don't get Madison Bumgarner back until Tuesday and remain without injured Johnny Cueto. Because of this some young San Francisco pitchers have had to make starts. Dereck Rodriguez gets that chance in this game. This will be his first big league start. He pitched for the first time in the majors this past Tuesday and gave up four runs in 3 1/3 innings against the Rockies. 

Arrieta versus the largely untested Rodriguez is a huge edge for the Phillies, who have also been getting great bullpen pitching. This edge is even higher considering the Giants could be without their two best offensive players. Brandon Belt is on the DL with an appendectomy and Buster Posey is day-to-day because of a bruised elbow.
