The Hall of Fame official has been following Barry Bonds’ pursuit of Hank Aaron’s all-time home run record since last Tuesday, including Bonds’ 755th round-tripper Saturday night, which tied him with ``Hammerin’ Hank.’’

Bonds, a leftfielder for the San Francisco Giants, broke the record in the fifth inning of Tuesday night’s home game against the Washington Nationals with a long home run to right-center field.

``It was an electric moment,’’ Idelson said by cell phone from San Francisco Wednesday morning. ``It was a moment in time when a record that regard with the greatest sanctity in baseball was broken.’’

Idelson said he met with Bonds in the Giants clubhouse during the 8th inning of Tuesday’s game and was presented the helmet Bonds was wearing. In addition, Bonds said the uniform he wore Tuesday will eventually be donated to the Hall after his career ends.

In addition to Idelson, approximately 500 media members have been traveling with the team over the past week.

``Barry said during his press conference after hitting 755 that he felt more pressure tying Aaron and now feels more comfortable,’’ Idelson said. ``So I’m not surprised he was able to get this over quickly.’’

Idelson said Bonds sought him out in the clubhouse after Saturday night’s game in San Diego to give him the helmet he wore that night.

``He has been very generous and said he’s glad the items are going to Cooperstown.’’

Idelson said when Bonds tied the home run mark in San Diego, he was cheered loudly and the Padre fans booed their own pitcher when Bonds walked in his next at bat. Bonds is highly suspected of using steroids late in his career, including during his record 73 home run season in 2001, but Idelson said the atmosphere has been positive for the most part at all the games.

The Giants have had 27 consecutive sellouts despite being in last place, and all the Giants road games have been sold out as well.

``It’s been an economic boon for the Giants and the teams they’ve been playing,’’ Idelson said.

The Hall of Fame is also expecting to receive artifacts from two other significant milestones attained last week by New York players.

Mets’ pitcher Tom Glavine won his 300th career game Sunday night in Chicago, and Idelson said he has agreed to donate his road jersey from the game and a game-used ball signed by himself and catcher Paul LoDuca.

``We’re just trying to work out when we can go to Shea Stadium and receive the items,’’ Idelson said.

In addition, the Hall is expecting to receive the helmet worn by Yankees third baseman Alex Rodriguez when he hit his 500th home run against the Kansas City Royals Saturday afternoon. Details have not yet been finalized.

Rodriguez is the youngest player ever to reach 500 home runs, and many baseball experts believe he will eventually be the all-time home run king.

On Aug. 12, Hall official Brad Horn will attend a ceremony in Houston, when the Astros’ Craig Biggio will donate the bat and spikes from his 3,000th hit which he collected earlier this year.

Idelson said the Hall is also expecting to receive items from the Mets’ Pedro Martinez when he collects his 3,000th strikeout, and from the Reds’ Ken Griffey Jr. when he hits his 600th career home run. Martinez, who has been on the disabled list all season but is expected back later this month, is two strikeouts away from 3,000 and Griffey has 589 career home runs.
