Babe Ruth’s career home run record lasted more than 38 years. Hank Aaron broke that in 1974 and his mark has been on the books until Tuesday night, when Barry Bonds broke it with a solo homer.

On deck, Alex Rodriguez is already positioned to eclipse Bonds in a few years and become the next great home run champ.

With all the debate surrounding Bonds’ chase to his 756th career homer Tuesday, which gave him one of baseball’s most time-honored records, some questions arise about sports records in general: Which are the most impressive? Most venerable? Most difficult to break?

“We’re in a society of ‘big,”’ said Joe Theismann, the retired quarterback whose streak of 163 straight starts for the Redskins ended when Lawrence Taylor gruesomely snapped his leg on “Monday Night Football.”

“I live in my own little world of consistency and durability,” Theismann said.

Not surprisingly, the records that impress him most are Brett Favre’s streak of 237 straight starts for a quarterback, and Joe DiMaggio’s 56-game hitting streak back in 1941.

When Bonds surpassed Aaron’s record, it figures that DiMaggio’s streak will stand with Cal Ripken’s 2,632 consecutive games streak as the two remaining “definitive” records in baseball.

Cy Young’s record of 511 pitching victories is 96 years old and will probably never be broken, though the number itself isn’t part of the baseball lexicon the way DiMaggio’s is and the record Ripken broke — Lou Gehrig’s old consecutive-games streak of 2,130 — once was.

Both had to do with consistency more than power.

DiMaggio’s has stood the test of time; only one player, Pete Rose, has gotten past 40 in the 66 years since.

Gehrig’s record lasted 43 years, and when Ripken passed it and set the new mark, he posted a number that may never be broken. Last month, Baltimore shortstop Miguel Tejada broke his wrist, snapping his 1,152-game streak. The longest current streak of games played now belongs to Juan Pierre, who was at 364 through last weekend.

“If I was able to do it, certainly somebody else can do it,” Ripken said. “I wasn’t Superman by any means, and it takes a special set of circumstances, a little bit of stubbornness and a lot of luck, and it can be done.”

Not so, says Derek Jeter of the Yankees.

“I don’t think that can be broken,” Jeter said. “It’s hard enough to play for a week, man, let alone for 14 years.”

Of course, every sport defines record-setting greatness in different ways.

Among basketball’s greatest records are Wilt Chamberlain’s 100-point game in 1962 and Bill Walton’s 95 percent (21-for-22) shooting effort in the 1973 national title game. Walton’s feat came in the midst of another impressive record, albeit on the team level — UCLA’s 88-game winning streak from 1971-74.

“UCLA’s winning streak, that’s my greatest thrill,” said former Notre Dame coach Digger Phelps, who, of course, coached the team that snapped the streak. “That and DiMaggio’s 56-game hitting streak.”
