The Washington Nationals have won 12 of their last 14 and look to complete the sweep of this four-game set Sunday night. The Arizona Diamondbacks can't be too happy about losing four in a row and being held to just one run in each of the three losses to the Nats, and I really expect them to show up tonight.

The Nats' Jeremy Hellickson (1-0, 2.28 ERA) took a perfect game into the seventh inning of his last start at San Diego, but note that he's 0-3 with a 4.94 ERA in five career starts against the Diamondbacks. Zack Godley (4-2, 3.83 ERA) will take the ball for Arizona. He's been dominant home at Chase Field this season, going 2-1 with a 1.96 ERA. Godley is 3-1 with a 4.00 ERA in six career appearances (four starts) against the Nationals.

Diamondbacks are 8-3 in their last 11 Sunday games.

10* play on Arizona Diamondbacks.
