The surging Washington Nationals had their way with NL ERA leader Ryan Vogelsong, and then some.
Vogelsong couldn't make it out of the third inning — and he wasn't the first member of the Giants to leave the game. San Francisco manager Bruce Bochy was ejected in the top of the second by first base umpire Jerry Layne for arguing a call.
"What is disappointing is I felt good and my stuff was good," Vogelsong said after the Washington Nationals routed the Giants 14-2 Monday night in a matchup of NL division leaders. "I threw good pitches. They put it in play — just not at anybody."
Gio Gonzalez (15-6) tied a Nationals record for wins in a season, boosted by Washington's highest-scoring game of the year.
The Nationals led 14-0 in the fifth and won for the 11th time in 13 games. They are 7-1 on this road trip.
Kurt Suzuki drove in four runs for Washington. Danny Espinosa and Roger Bernadina each knocked in three.
Vogelsong (10-6) allowed eight runs and nine hits in 2 2-3 innings, his shortest outing of the season. His ERA spiked from 2.27 to 2.72.
"There's not a whole lot to say," Bochy said. "What could go wrong went wrong and they made some pretty good contact. They placed the ball well and we couldn't stop it."
Pinch-hitter Brandon Crawford homered and drove in both runs for the Giants, who have lost three of five. The defeat dropped San Francisco into a tie with the Los Angeles Dodgers for the NL West lead.
Vogelsong ended the night with the fourth-best ERA in the NL. Of the 19 batters he faced, 11 reached base. He had not pitched fewer than six innings in a start this season and had not allowed more than two runs in any of his previous 11 home starts.
"Sharpness was not the issue," Vogelsong said. "Sometimes the ball doesn't bounce your way. It's part of the game. I have the whole rest of the season to not let one start ruin it."
Bernadina had four of Washington's 21 hits, the most by a visiting team at AT&T Park.
Washington has won 13 of its past 14 road games and owns the best road winning percentage in the majors.
"You play the game the right way and you get rewarded for it," Ryan Zimmerman said. "We just got some big hits and that was it."
The Nationals have scored a major league-best 170 runs since the All-Star break. The Giants are second with 153.
Washington has outscored San Francisco 38-14 in four meetings this season, all wins.
"The boys are in a good mood tonight," Nationals manager Davey Johnson said. "Just like the skipper. It was fun to watch the offense. We beat up on a pretty good pitcher."
Gonzalez returned to the Bay Area for the first time since the Oakland Athletics traded him to the Nationals during the offseason. He won his second straight after going 1-3 in his five previous starts.
The left-hander gave up two runs and six hits over 6 2-3 innings.
"Most importantly, they came up big and gave me something to work with," Gonzalez said. "My thought from the get-go was just to maintain, especially with the pitcher they had today. He's not an easy guy to go out there and get a couple of runs off of and right off the bat these guys are swinging the bat. Can't complain with some runs."
