WASHINGTON (AP) -- Austin Voth threw his first career complete game and earned his first victory in 10 starts this season, and the Washington Nationals staved off playoff elimination with a 5-1 victory over the Philadelphia Phillies in the first game of a doubleheader Tuesday.
The Phillies fell into a tie with Milwaukee and San Francisco for the last wild card spot in the National League.
Voth (1-5) posted season highs in innings (seven) and strikeouts (seven), allowing three hits and one run. It was an especially welcome effort for the Nationals, who were playing their third doubleheader in five days.
Philadelphia's defensive woes didn't help Aaron Nola (5-4), who yielded five runs (three earned) in six innings while striking out six. Washington collected an unearned run in the first when Juan Soto reached on left fielder Mickey Moniak's error and scored on Asdrubal Cabrera's single.
Andrew Stevenson and Trea Turner opened the third with back-to-back doubles to make it 2-0. After an intentional walk and a fielder's choice grounder, Brock Holt smacked a hard grounder down the right-field line to score a run. Bryce Harper, playing the field for the first time since leaving Sunday's game with back discomfort, misplayed the ball in the corner to let in another run.
Holt scored on Luis Garcia's infield single two batters later to make it 5-0.
Jean Segura's fourth-inning home run accounted for Philadelphia's only run.
The doubleheader includes a makeup of an Aug. 27 game postponed as a response to racial injustice in the wake of a police officer shooting Jacob Blake, a Black man, in Kenosha, Wisconsin, four days earlier.
Phillies: C J.T. Realmuto (hip) returned for the first time since Sept. 12 and started the opener of the doubleheader. Realmuto, who missed 11 games, went 1 for 3. . RHP Spencer Howard (shoulder) threw a bullpen session Monday. . Manager Joe Girardi said 1B Rhys Hoskins (left elbow strain) would undergo treatment Tuesday and might pick up a bat. Hoskins went on the injured list Sept. 15.
Nationals: Manager Dave Martinez said INF Howie Kendrick (left hamstring strain) still wants to return this week but has reached a ''stalemate'' in his recovery. ''He's definitely pushing to come back and at least DH one game or play or something,'' Martinez said. ''We'll see how he feels.'' . 3B Carter Kieboom (bruised left hand) was out of the lineup but was expected to try to take some swings Tuesday.
Philadelphia added LHP Ranger Suarez as its 29th man for the doubleheader. Suarez is 0-1 with a 20.25 ERA in three appearances this season. . Washington brought up RHP Wil Crowe (0-2, 11.88) as its 29th man. Crowe's three appearances this season have come as a starter in the nightcap of a doubleheader.
Phillies: RHP Zach Eflin (3-2, 4.28 ERA), who tossed a seven-inning shutout against Toronto in his last outing, is 3-3 with a 4.43 ERA in eight lifetime starts against Washington.
Nationals: RHP Erick Fedde (2-3, 4.36) threw six shutout innings in his last start Friday at Miami and draws the nod as the four-game series concludes.
