For just the second time all season, the Nationals are at full strength offensively.

Anthony Rendon, Ryan Zimmerman and Jayson Werth are all healthy joining Bryce Harper and Ian Desmond to help boost the Nationals' offense. The last time Harper faced Marlins starter Tom Koehler he homered three times off him. That was on May 6 when the Nationals won, 7-5.

Koehler has been pitching well lately, but he is who he is and that's a journeyman.

I like Nationals starter Doug Fister better especially now that the Nationals have fortified their bullpen adding Jonathan Papelbon to go with Drew Storen. Papelbon and Storen are a combined 46 for 48 in save opportunities this season.

Fister has a strong history versus the Marlins with a 2-0 career mark and 1.09 ERA in four career appearances. Fister hasn't pitched well this month, but that should change here facing a team he has dominated and with an extra day of rest. Washington is 10-3 when Fister has pitched on five days rest.

The Marlins lack power without injured Giancarlo Stanton.
