LOS ANGELES — Brad Hennessey would like to have one pitch back — the changeup that hit Jeff Kent in the head.

Otherwise, his first start of the season for the San Francisco Giants was nearly flawless.

Hennessey worked 6 1/3 strong innings, three relievers combined to finish a three-hit shutout, and the Giants beat the Los Angeles Dodgers, 2-0, last night despite another tough game at the plate for Barry Bonds.

Hennessey (1-0) allowed three hits while walking three and striking out two before being relieved by Scott Munter with the bases loaded and one out in the seventh. Munter worked out of trouble by striking out pinch-hitter Ricky Ledee and retiring Dioner Navarro on a fly to right.

Tim Worrell, the fourth Giants pitcher, retired Ramon Martinez with two on and two out to end the eighth, and worked a perfect ninth for his fifth save in five chances.

"I felt confident in what I was doing, in control of myself. That made it easier," said Hennessey, who found out Saturday he was being recalled from Triple-A Fresno to face the Dodgers.

Kent came out of the game after being beaned in the seventh. He was hit on the helmet just behind his left temple on the first pitch from Hennessey with one on and nobody out. Hennessey faced two more batters before being relieved.

Kent went to Good Samaritan Hospital for a CT scan, which showed he suffered a slight concussion. He had some blurry vision in his left eye and will see an ophthalmologist today, according to team spokesman Josh Rawitch.

"It was a changeup — I was trying to get ahead," Hennessey said. "It came out of my hand early; my release point got screwed up."

Bonds went hitless in two at-bats, making him 4 for 23 this season.

Phillies 1, Rockies 0: Philadelphia's Brett Myers combined with two relievers on a seven-hit shutout and Ryan Howard homered in the first 1-0 win by a visiting team at Coors Field. In 888 regular-season games at Coors Field, the only other 1-0 game was last July 9, when the Rockies beat San Diego. Myers (1-0) allowed seven hits in 7 2/3 innings, struck out five and walked one.

Mets 9, Brewers 3: Xavier Nady drove in three runs with a home run and a sacrifice fly and Carlos Delgado hit a three-run homer for host New York. Milwaukee pitcher Ben Sheets (0-1) allowed six hits and four runs in five innings. Sheets was activated from the disabled list before the game and had not pitched since Aug. 26 because of a right shoulder strain.

Padres 4, Braves 3: Brian Giles homered to help visiting San Diego avoid a three-game sweep. Atlanta led 3-0 before Giles' solo homer in the seventh off Ken Ray, who had just entered the game. Dave Roberts tripled off Mike Remlinger (1-1) in the eighth and scored on pinch-hitter Eric Young's infield single to put San Diego ahead.

Nationals 7, Marlins 5: Ryan Church hit a pair of two-run homers, including a tiebreaking drive in a three-run ninth inning for visiting Washington. Florida took a 5-4 lead in the eighth against Gary Majewski (1-0) when Miguel Olivo hit an RBI double and scored on a triple by pinch-hitter Wes Helms.

Astros 8, Diamondbacks 5: Lance Berkman had three hits and three RBIs and Morgan Ensberg hit a three-run homer to power visiting Houston. Ensberg's second homer in as many games came off reliever Jason Grimsley and capped the Astros' seven-run sixth inning.

Cubs 7, Pirates 3: Todd Walker hit a two-run homer in the first inning and Aramis Ramirez added a two-run shot for visiting Chicago. Derrek Lee hit a two-run double that chased starter Ian Snell (0-1) in a four-run sixth.
