SAN FRANCISCO — Barry Bonds raised both arms over his head like a prize fighter in victory, fists clenched — and then he took off.

It was over at long last.

Like him or not, legitimate or not, he is baseball's new home run king.

Bonds hit No. 756 to the deepest part of the ballpark last night, and hammered home that very point. He broke Hank Aaron's storied record with one out in the fifth inning, hitting a full-count, 84 mph fastball from Washington's Mike Bacsik.

Bonds sent the ball arcing high into the night, 435 feet into the right-center field seats. Later, he firmly and flatly rejected any suggestion that this milestone was stained by steroids.

"This record is not tainted at all. At all. Period," Bonds said.

Conspicuous by their absence were the commissioner and Hammerin' Hank himself.

Though he was on hand for the tying homer three days ago, deciding to put baseball history ahead of the suspicions plaguing the Giants slugger, Bud Selig wasn't there for the record-breaker.

Instead, he sent two emissaries, Major League Baseball executive vice president Jimmie Lee Solomon and Hall of Famer Frank Robinson. Selig also issued a statement.

"While the issues which have swirled around this record will continue to work themselves toward resolution, today is a day for congratulations on a truly remarkable achievement," Selig said.

Bonds also heard personally from the commissioner.

"Bud Selig called me after the game and congratulated me. I was very happy about that," Bonds said.

As for Aaron, he said all along he had no interest in being there whenever and wherever his 33-year-old mark was broken. He was true to his word, but he did offer a taped message of congratulations that played on the stadium's video board during a 10-minute, in-game tribute.

"It is a great accomplishment which required skill, longevity and determination," he said.

"Throughout the past century, the home run has held a special place in baseball and I have been privileged to hold this record for 33 of those years. I move over now and offer my best wishes to Barry and his family on this historic achievement.

"My hope today, as it was on that April evening in 1974, is that the achievement of this record will inspire others to chase their own dreams," Aaron said.

A woman who answered the phone at Aaron's home in Georgia shortly after Bonds' homer said that Aaron was asleep.

"When I saw Hank Aaron that made everything," Bonds said. "We've always loved him. He's always the home run king."

With a long, satisfied stare, Bonds watched as the ball sailed over the fence and disappeared into the scrum in the first few rows. Then he raised both arms over his head before starting to run toward first base.

"I knew I hit it," Bonds said. "I knew I got it. I was like, phew, finally."

His 17-year-old batboy son Nikolai was already bouncing on home plate as Bonds rounded third and ran the final 90 feet to make it official. After a long embrace, the rest of the family joined in — his mother, two daughters and wife. And then there was Willie Mays, who removed his cap and congratulated his godson.

Bonds saved his most poignant words for last, addressing his late father, Bobby.

"My dad," he said, looking to the sky and choking back tears. "Thank you."

After doubling and singling his first two times up, Bonds hit a solo home run. Bacsik put his left hand to the back of his head as soon as Bonds connected.

"I didn't really want to be part of history as a bad part, but I am," Bacsik said. "I'm OK with it."

Bonds took his position in left field to start the sixth, then was replaced and drew another standing ovation. The Nationals won the game, 8-6.

Even with Bonds at the top of the chart, fans will surely keep debating which slugger they consider the true home run champion. Some will continue to cling to Aaron while other, older rooters will always say it's Babe Ruth.

"It's all about history. Pretty soon, someone will come along and pass him," Mays said before the game.

Aaron held the top spot for 12,173 days after connecting for No. 715 to pass the Babe on April 8, 1974.

"This is the greatest record in all of sports," Giants manager Bruce Bochy said. "We are all fortunate to witness it. It's awesome. This road to history has been a lot of fun."
