Every time Phil Niekro returns to Cooperstown, N.Y., he makes a beeline for the Baseball Hall of Fame.

"I love coming back here, especially when your plaque's hanging on the wall," the former Atlanta Braves knuckleballer said. "And it's still there. I keep checking. You can't help not to."

Niekro returned to Cooperstown yesterday, but his plaque was an afterthought. The Hall of Fame celebrated its 60th anniversary, and Niekro was one of the guests of honor.

"There's a mystique about this town that I've never felt in any other little town I've ever been to," Niekro said. "It's a family town. It's super-friendly. It's got the lake, it's got the hills, it's got the fresh air. It's got everything you want in a little town."

It also had a parade, with Niekro, former Baltimore Orioles third baseman Brooks Robinson and longtime Philadelphia Phillies pitcher Robin Roberts leading the way. . . .

The house of Ruth was robbed again.

For the third time in two weeks, two masked gunmen held up employees at the Babe Ruth Museum and Birthplace in Baltimore, police said. The robbers, one of whom wielded a silver-plated handgun, made off with an undetermined amount of cash.

Investigators believe the same pair committed all three robberies, police spokesman Sgt. Scott Rowe said.

Olympics

Sydney Unveils Stadium

Sydney's $450 million main Olympic stadium officially was opened by a stellar cast of world soccer talent and an emotional performance from pop group INXS.

Italy's Christian Vieri joined a FIFA all-star team against Australia's national side for an exhibition game after a two-hour ceremony.

Australia won, 3-2, in front of 88,101 fans, a record for a soccer match in the country.

Although Sydney Olympics President Michael Knight declared the venue open, more than 104,000 fans watched a rugby league doubleheader there four months ago. Another 88,000 watched Wednesday's rugby league representative match in torrential rain that caused parts of the roof to leak. . . .

International Olympic Committee member Kim Un Yong alleged there was a "dirty plot" to discredit him as he hosted an IOC general assembly in his home town of Seoul.

Kim, the most experienced official implicated in the Salt Lake City Olympic bribery scandal, sought to rebuild his tarnished reputation during the IOC meeting, which began yesterday. But on the eve of the meeting, USA Today reported that Salt Lake City Olympic bidders appeared to have used a small, now-bankrupt company to pass money to underwrite the salary of Kim's businessman son, John Kim.

"I cannot help wondering about the timing of this dirty plot," the elder Kim said of the report. "I can guess the motive behind it."

Kim refused to elaborate, but said previously that opponents inside the IOC were trying to discredit him as a possible candidate to replace Juan Antonio Samaranch as IOC president in 2001.
