La Jollan looks to authenticate Clemente cap's World Series origins

PITTSBURGH – An aged black baseball cap with a flattened bill and a gold letter "P" on the front could fetch as much as $30,000 at auction, if the owner can prove it isn't just any hat, but one worn by Pirates great Roberto Clemente during the seventh game of the 1960 World Series.
Before most savvy sports memorabilia collectors will shell out thousands of dollars, Howard G. Singer must not only authenticate the hat's original owner but also prove his remarkable story that he grabbed it from Clemente's head 43 years ago during the chaos that followed the winning home run of the deciding game of the series between the Pirates and the New York Yankees.
Singer's quest to find witnesses and evidence to back up his story brought him to Pittsburgh on Monday as a group of Pirates fans gathered at the last remnants of Forbes Field – an outfield wall – to celebrate the anniversary of one of the most unpredictable World Series of all time.
Singer, a Pittsburgh native who lives in La Jolla, Calif., was a 19-year-old baseball fan when he attended the Oct. 13, 1960 game. At that point, the Yankees had outscored the Pirates 46-17 – winning Game 2 16-3 and Game 3 10-0 – and most bookmakers had quit posting odds, figuring the home team had no chance.
According to Singer's story, he made his way to the railing near the Pirates' dugout at the end of the eighth inning, with the feeling that Pittsburgh might pull through. If so, his plan was to pry home plate off the field during the post-game celebration as a souvenir.
The Yankees had tied the game 9-9 in the ninth when Bill Mazeroski, who hit only 11 homers during the season, hit a decisive home run. It's considered one of the greatest late-inning World Series comebacks ever.
Singer never grabbed home plate because two sheriff's deputies stopped him in the act, but it turns out that he might have gotten a more valuable item.
As he made his way to home plate, Singer grabbed the hat off a player's head – he didn't notice who – and stuffed it under his shirt. It wasn't until he was on the trolley headed home that he noticed the "21" written in felt-tip pen on the inside of the hat and realized that he had grabbed Clemente's cap.
"This isn't stolen property," Singer said. "Players will tell you that a lot of guys lost caps and gloves on the way to the clubhouse. Now they didn't really lose them. Fans found them. The ball club is the one who really owns this cap, but the Pirates never asked for it back."
It hasn't been hard for Singer to prove that the cap once belonged to Clemente. At the urging of a columnist at the Pittsburgh Post-Gazette, Singer tracked down Chuck Cirelli, who as a teenager worked in the locker rooms at Forbes Field from the late 1950s to the 1970s and now authenticates Pirates memorabilia.
"It's a good hat. I know it belong to Clemente because that's the way (the equipment manager) used to write the number," Cirelli said. "What I can't say is if he took it off Clemente's head that day."
Victor Moreno, the owner of American Memorabilia, a Las Vegas-based sports and celebrity auction house, doesn't doubt Singer's story. He just wants Singer to produce tangible proof of the story so potential bidders will believe it, too.
A cap worn by Clemente garnered a winning bid of $6,555 at an auction in September, Moreno said.
But if Singer could produce some definitive evidence that reinforces his story, such as a photo of him taking the cap off of Clemente's head, the hat could fetch between $25,000 to $30,000 at an auction, Moreno said. Clemente wore lots of caps, after all, but there was only one he likely donned during that seventh game.
Singer recently discovered a photo of fans greeting Mazeroski at home plate and Singer can be seen in the left corner of the image. That, he said, proves he was at the game. Singer also knows of a video that shows Clemente walking around the field capless.
"When you put those two things together, I can assume that his story's legit. He's got to have stronger evidence before someone's going to be willing to fork over 25 grand," Moreno said.
