WASHINGTON (AP) – Alfonso Soriano homered twice and drove in four runs, and Pedro Astacio won his Washington debut in the Nationals’ 9-1 victory over the Florida Marlins on Monday night.

Soriano led off the first inning with a homer and added a two-run shot in the fifth for his third multihomer game this season. Jose Guillen had a three-run drive in the fifth, and Jose Vidro added three hits to help the Nationals win their third in a row.

Astacio (1-0), who missed the first three months of the season with a right forearm strain, was strong in his first start, using a fastball that topped out at 89 mph and a sharp curveball. He allowed three hits in five innings, giving up his only run on Reggie Abercrombie’s homer in the fifth. The right-hander finished with one walk and two strikeouts.

Marlins starter Ricky Nolasco (6-5) was hit hard in four innings, lasting only 62 pitches. He was tagged for a season-high eight runs, seven earned, and seven hits before being removed with none out in the fifth. He walked one and struck out two.

Soriano, elected by fans to start the All-Star game in his first season as an outfielder, led off the bottom of the first with his first home run since June 16. The Nationals added three more in the second on Brian Schneider’s RBI single, a wild pitch that scored Royce Clayton, and Soriano’s sacrifice fly.

Washington chased Nolasco during a five-run fifth. Pinch-hitter Damian Jackson was hit by a pitch and scored on Soriano’s 26th homer. Vidro and Ryan Zimmerman followed with singles, ending Nolasco’s night. One out later, Guillen hit his ninth home run down the left-field line off reliever Matt Herges.

Saul Rivera pitched three scoreless innings of relief for the Nationals.

Notes: Soriano’s leadoff home run was his second this year and the 25th of his career. His previous one came on April 21 against Atlanta, when he finished with three homers. His four RBIs were his most since driving in five runs on June 4 at Milwaukee. … Soriano’s outfield assist in the seventh was his 12th of the season. … With an attendance of 24,943, the Nationals passed the 1 million mark in their 38th home game. Last year, their first in Washington, the Nationals passed the 1 million plateau in their 32nd game. … Schneider got his first RBI since June 19. … Nolasco has alternated wins and losses in his last eight starts, going 4-4 since May 22. … During his major league career as a catcher, Marlins manager Joe Girardi was successful against Astacio, hitting .375 (9-for-24) with a home run.
