SAN FRANCISCO -- The Washington Nationals know they will win their share of games if they keep hitting this well.
Ryan Church had a three-run double and Brad Wilkerson added three hits and drew a bases-loaded walk in another strong offensive night for the Nationals, who beat the San Francisco Giants 9-3 on Friday.
Vinny Castilla hit a two-run single, Gary Bennett had an RBI double and also singled, and Nick Johnson had two hits as the Nationals produced 10 or more hits for the fourth consecutive game and fifth in six.
"We have a lot of one-run games, but this offense can put up some runs any given day," Church said. "We have to stay focused with it every day."
Starter Tomo Ohka settled down after a shaky second inning, but manager Frank Robinson went to reliever Jon Rauch to start the fifth. The right-hander walked two of his first three batters, but induced Pedro Feliz to hit into an inning-ending double play.
Rauch (1-1) walked two more in the seventh but again escaped unscathed, pitching three effective innings for the win.
Deivi Cruz homered and Feliz doubled for the only other extra-base hit for the Giants, who lost their third in a row following a six-game winning streak.
Washington tagged left-hander Noah Lowry for six hits in its four-run third, batting around and getting RBI singles from Jamey Carroll and Johnson as well as Castilla's hit.
"That's what it takes, big hits and timely hitting," Robinson said. "A lot of people now are starting to contribute to the overall success of the team."
Lowry (1-3) had a season-high seven strikeouts and retired 12 of his last 13 batters after Johnson's single before giving way to Tyler Walker. Lowry, a lefty in his first full major-league season, hasn't won since April 15, a span of four starts. He began his big league career 7-0 dating to last season -- the second-longest career-opening winning streak in franchise history.
"Lowry pitched a lot better than the last couple of outings," Giants manager Felipe Alou said. "Why we're walking so many guys, pitching away from the bats this year, I don't understand that."
The Giants staked Lowry to a 2-0 lead in the second on Edgardo Alfonzo's RBI bloop single and a sacrifice fly by Mike Matheny. Cruz connected for his second homer leading off the third, sending a 2-0 pitch from Ohka over the left-field fence.
Washington's Jose Guillen went 0-for-3 with a strikeout and has only one hit in 14 at-bats (.071) over his last eight games. He left Friday's game after being hit by a pitch from Walker and was replaced by Church, who put the game out of reach with his hit in Washington's five-run eighth.
"A couple fell in the right place, a couple were hit hard," said Matheny, San Francisco's catcher. "When they had opportunities, they capitalized."
Guillen sustained a bruised left triceps. He is listed as day-to-day.
"Not good," said Robinson, who expects the right fielder to miss a few days.
The Giants loaded the bases against Chad Cordero with one out in the ninth on a walk and consecutive singles by Omar Vizquel and Cruz, but J.T. Snow flied to left and Moises Alou lined to third.
Vizquel tied Rabbit Maranville for seventh on the all-time list for games by a shortstop (2,153).
San Francisco played without injured second baseman Ray Durham, who is nursing a strained left groin and could go on the disabled list.
The Nationals are 6-1 vs. the NL West. ... Barry Bonds is undergoing aggressive antibiotic therapy on his troublesome right knee and the Giants announced that Dr. Arthur J. Ting will remain involved in the slugger's care, a day after a newspaper report that Ting has been reprimanded twice by the Medical Board of California. The Giants said in a press release they will provide updates on Bonds' condition "as events warrant." Bonds wants all information on his health to be disseminated via his website, www.barrybonds.com, which he hasn't updated since Tuesday. ... Nationals OF Terrmel Sledge had surgery on his ruptured right hamstring. He will be sidelined four to six months. The procedure was performed in Los Angeles. Sledge's muscle tore off the bone when he was chasing Hee-Seop Choi's double in the sixth inning of Monday night's 6-2 victory over the Dodgers. ... Washington 2B Jose Vidro's tender left ankle was examined by Giants orthopedist Ken Akizuki. X-rays were scheduled for Friday night at the ballpark and Vidro will have an MRI exam Saturday. The team said Vidro is expected to miss three to five days. He came out of Wednesday's game in Los Angeles in the late innings.
