The Miami Marlins started the second half of the season by getting swept over three games at Philadelphia and they have since split the first two games of this series in Arizona. The D'Backs will be looking to avenge a 3-0 loss last night, but they'll have to get to Miami's ace in order to do so.

Here are my keys to the game:

1. Pitching - The Fish hand the ball to Jose Fernandez, who will make just his fourth start since returning from injury. Fernandez (2-0, 2.37 ERA) allowed a pair of runs on four hits over six innings in a loss at Philadelphia in his last outing. He's always been a far better home pitcher, while his record of 4-8 with a 3.93 ERA on the road leaves a lot to be desired. The D'Backs will counter with Robbie Ray, who owns an impressive 2.39 ERA in nine starts this year.

2. Injuries - With Dee Gordon and Giancarlo Stanton both sideline by injuries, the Marlins lineup is pretty thin.

3. X-Factor - Paul Goldschmidt is 6-for-14 since the All Star break and he leads the NL batting .341 with 72 RBIs.

Selection: This is a play on the Arizona D'backs (10*)
