Game 34 lineups: Nats at Diamondbacks

PHOENIX – The Nationals once again find themselves needing to win a series finale to avoid a three-game sweep. This is the fifth time already this season it’s happened, but the good news is they’re 3-1 in such matchups, having beaten the Braves, Guardians and Pirates. Only the ridiculously hot Rays managed to pull off a three-game sweep against them.

So they’ll try to make it 4-1 this afternoon when they face the Diamondbacks one last time at Chase Field, this time with the roof closed. The dry air has been good for a power-starved lineup: Luis García, Keibert Ruiz and Lane Thomas have all homered in this series. Unfortunately, Arizona also has hit three homers, including Lourdes Gurriel Jr.’s game-tying blast to lead off the bottom of the ninth Saturday night.

We’ll have to see if Kyle Finnegan is used as closer again today, should the situation present itself. Davey Martinez certainly has an easy out if he wants to sit Finnegan, citing the four games in five days he has pitched. Would he instead go to Hunter Harvey, who has had two days off after pitching back-to-back-to-back days, for his first career save? Stay tuned.

Trevor Williams gets the start, and the right-hander will be looking to pick up right where he left off Tuesday night when he tossed 5 1/3 scoreless innings against the Cubs at Nationals Park. He’s opposed by Diamondbacks right-hander Ryne Nelson, who in six starts this season owns a 6.39 ERA and 1.516 WHIP.
