The Giants will have their hands full with Phillies right-hander Jake Arrieta (5-2, 2.16 ERA) in the series finale Sunday afternoon at AT&T Park. Arrieta has won four of his last five starts against San Francisco. Dereck Rodriguez, son of Hall of Famer Ivan Rodriguez, makes his first career start for the Giants. The right-hander made his Major League debut Tuesday when he pitched 3 1/3 innings of relief but left after getting hit in the shin by a 108 mph line drive.
