MIAMI — Sandy Alcantara pitched nine scoreless innings, Jesús Aguilar hit a game-ending single in the 10th inning and the Miami Marlins beat the Washington Nationals 2-1 Wednesday night.

Alcantara extended his scoreless string to 18 innings and has completed at least eight innings in four of his past five starts. The 26-year-old allowed six hits and struck out six while lowering his ERA to 1.61.

Aguilar’s smash against reliever Tanner Rainey (1-2) deflected off second base and rolled into center field, scoring Willians Astudillo from second. Astudillo’s run-scoring single to right scored automatic runner Jazz Chisholm Jr. from second to tie it.

Chisholm originally was called out, but the Marlins successfully appealed that he beat right-fielder Juan Soto’s throw.

Keibert Ruiz’s RBI single against Tanner Scott (2-1) in the top half put Washington ahead 1-0.

Nationals starter Josiah Gray pitched five scoreless innings but was lifted after a season-high 101 pitches. Gray allowed six hits, walked one and struck out six.

Miami left fielder Jorge Soler misplayed Soto’s drive to the warning track that fell for a one-out double in the sixth. Soto advanced on Nelson Cruz’s groundout to third, but Alcantara retired Josh Bell on a groundout to second to strand him.

The Marlins loaded the bases with one out in the first, but Gray struck out Avisaíl García and Jon Berti to end the threat.

ADON SENT DOWN

In the aftermath of Joan Adon’s outing of three-plus innings and eight runs allowed Tuesday, the Nationals optioned the 23-year-old right-hander to Triple-A Rochester. Adon made the opening day roster but has struggled to a 1-10 record and 6.95 ERA in 12 starts. LHP Sam Clay was recalled from Triple-A.
