Phoenix ? Barry Bonds looked up and pointed toward the sky, just as he does after every home run.

But this was no ordinary homer. His heart told him so.

Overwhelmed by emotion after connecting in his first game back following his father’s death, Bonds later left the San Francisco Giants’ 2-1 victory over the Arizona Diamondbacks Saturday because of an accelerated heart rate.

“It’s tough. I lost my coach,” Bonds said.

His father, Bobby, died Aug. 23 at age 57 after being ill for nearly a year because of lung cancer and a brain tumor.

“The emotions just went through me, I felt lightheaded and couldn’t stop my heart rate from racing,” Bonds said. “After the home run I couldn’t breathe. I tried to stay in there as long as I could. That’s never happened to me.”

Resting on one knee in the on-deck circle when the top of the eighth ended, Bonds came out of the game in the bottom half. He left the Giants’ dugout shortly thereafter because of heart palpitations he said started with his homer off Randy Johnson.

San Francisco trainer Stan Conte said Bonds’ heart rate was between 150-160 beats per minute after the home run — a normal adult heart rate ranges from 60-100 beats per minute.

Bonds felt better after the game, and Conte said the team would monitor his heart rate through the night. Bonds was expected to play today.

“This guy has been through a lot of stress,” manager Felipe Alou said. “Then to show up and play right away is not an easy thing to do.”

Bonds homered in his second at-bat, leading rookie right-hander Jerome Williams and the Giants to an emotional victory.

Bonds, who missed six games after his father’s death, reached on an infield single in the first, then hit a 403-foot homer into the right-field stands leading off the fourth.

“If you believe in life after death, a lot of people were looking at that moment,” Alou said.

Dodgers 5, Rockies 0

Los Angeles — Jeromy Burnitz’s two-run single keyed a four-run sixth inning as Los Angeles beat Colorado. Guillermo Mota (4-2) gained the victory in relief of Kazuhisa Ishii for the Dodgers, who were held hitless through the first five innings by Denny Stark.

Cardinals 6, Reds 3

Cincinnati — Jim Edmonds drove in four runs with a homer and a double and made a sensational catch atop the centerfield wall, leading St. Louis past Cincinnati. The Cardinals’ first victory in six games at Great American Ball Park kept them in first place in the NL Central. St. Louis also got back its leadoff hitter. Fernando Vina was activated off the disabled list and singled in four at-bats.

Brewers 9, Cubs 5

Chicago — Richie Sexson homered and drove in four runs, Scott Podsednik stole home and Matt Kinney won his third straight start as Milwaukee beat Chicago. The Brewers had a 10-game winning streak — the second-longest in franchise history — snapped Friday. But they wasted little time starting another one, tagging starter Shawn Estes (7-11) for five runs in the first two innings.

Astros 11, Padres 6

Houston — Lance Berkman and Morgan Ensberg homered, and Jared Fernandez pitched six solid innings in Houston’s victory over San Diego. Fernandez (2-3) allowed one run and five hits as he snapped a personal three-game losing streak

Phillies 4, Mets 2

New York — Randy Wolf, coming off the worst start of his career, handcuffed New York for seven innings. The win kept the Phillies tied with Florida in the NL wild-card race. The Phillies bunched four singles against Tom Glavine (9-12) to break a 2-2 tie in the seventh. Marlon Byrd started the rally with a hit and raced to third on a hit-and-run single by Placido Polanco. Then RBI hits by Mike Lieberthal and Jason Michaels finished Glavine, who allowed 11 hits.

Marlins 4, Expos 3

Miami — Carl Pavano pitched eight-plus solid innings, and Juan Encarnacion drove in four runs as Florida beat Livan Hernandez and Montreal. Pavano (11-11) allowed four hits before Vladimir Guerrero led off the ninth with a solo homer to left field, and Wil Cordero’s single. Braden Looper yielded a two-run double to Brian Schneider with one out before getting the final two outs.

Braves 13, Pirates 6

Pittsburgh — Rookie Mike Hessman hit a two-run homer in only his second start for Atlanta, keying a seven-run third inning that ruined Oliver Perez’s debut with Pittsburgh.
