WASHINGTON — Luis Arráez led off the game with his sixth homer and scored the go-ahead run on a throwing error in the ninth inning as the Miami Marlins completed their first four-game sweep of the Washington Nationals with a 6-4 win on Sunday.
Sandy Alcantara worked eight strong innings as the Marlins moved three games over .500 in September for the first time in a full season since their 73-69 start in 2010. Miami entered Sunday’s action one game back in the race for the third and final wild-card berth in the National League.
With the game tied at 4 in the ninth, the Marlins moved ahead as Arráez scored on an errant throw on an attempted double play ball on Jazz Chisholm Jr.’s grounder to first. Later in the inning, Miami added an insurance run when a pop into shallow right field by Bryan De La Cruz fell for a hit and Chisholm scored.
Arráez went 2-for-4 and scored twice. He raised his major league-leading batting average to .356, 15 points higher than the Texas Rangers’ Corey Seager (.341).
Miami jumped out to a three-run lead in the top of the first on the strength of Arráez’s 375-foot opening homer and two walks with the bases loaded as Nationals starter Josiah Gray struggled at the outset. In the first, the 25-year-old right-hander gave up three hits and three walks. Gray has had trouble with his command the last six starts, issuing 20 walks, and has not recorded a victory since July 22.
Gray lasted four innings, allowing three runs on four hits with four walks and two strikeouts. He threw 86 pitches, 51 for strikes.
Alcantara (7-12) gave up a homer to Lane Thomas in the bottom of the first but prevented the Nationals from building any long rallies. He scattered nine hits, allowed four runs, two earned, struck out three and walked two. He threw 94 pitches, 63 for strikes.
The Marlins have won each of Alcantara’s last eight starts against the Nationals, dating to September 2021.
Tanner Scott worked the ninth inning and earned his fourth save.
Thomas went 3-for-5 with his 23rd homer of the season and drove in a pair of runs. Kyle Finnegan (6-4) took the loss.
