Game 42 lineups: Nats at Diamondbacks

PHOENIX - What a weekend it's been for the Nationals. They learned Adam Eaton needed arthroscopic ankle surgery. They lost Matt Wieters to a hamstring strain (and possibly a knee injury as well). They lost Ryan Zimmerman to an oblique strain. Not good, any of that. Oh, and they also won the first three games of this series against the best team in the National League.

Despite all their injury woes, the Nats are playing their best baseball of the season. They've won 12 of 14 overall, they've already dealt the Diamondbacks their first series loss of the season and tonight they have a chance to pull off a rare, four-game sweep on "Sunday Night Baseball."

It'll be Jeremy Hellickson on the mound, looking to continue his surprisingly dominant ways. The 31-year-old has a 2.28 ERA and 0.867 WHIP in five starts and of course carried a perfect game into the seventh inning in San Diego earlier in the week. The Nationals, who have scored only seven total runs the last three days, will be looking to duplicate their efforts against Zack Godley a couple weeks ago in D.C., when they amassed four runs on 10 hits in five innings vs. the Arizona right-hander.

It's a beautiful afternoon here in the desert, so beautiful they're planning to open the roof for the game. Happy Mother's Day to all, especially the two most important women in my life: my wife, Rachel, and my mom, Lois, who -- thanks to this nice quirk of the schedule -- I got to spend the day with!
