With the World Series underway, The Lint Screen is happy to continue its coverage of the world’s most valuable baseball, a story we broke back in the spring of 2010 (Part #1) (Part #2).

This ball was secured for an undisclosed sum on the internet and features autographs of some of the most impressive people in history. Let’s continue a look at the incredible baseball backstories of some of the signers.

Stevie Wonder played in a 1969 game for the Houston Astros against the Los Angeles Dodgers. Although the famous singer is sightless, he was used as a pinch hitter. The first pitch was a fastball on the outside right corner of the plate that the umpire called a strike. “What are you, blind?” Wonder said with a smile. The next pitch was a curve ball that hung over the plate. Wonder smacked a 500-foot shot over the right center field fence and trotted around the bases to deafening applause. He never played again, except for music. He played lots of music.

One of the most valuable signatures is that of Jonas Salk, the medical researcher who discovered the first polio vaccine. Salk was an enthusiastic Mets fan and was given the opportunity to pitch a game against the St. Louis Cardinals on July, 17, 1966. Salk walked the first 24 batters and was pulled. The distinguished doc was booed by angry fans. The guy sucked.

Janis Joplin had one trip to the plate for the Milwaukee Brewers in a game against the Yankees on May 28, 1970. She was hit by the first pitch, took her base, stole second, advanced to third on a error by the right fielder and scored on a sacrifice fly. “This is a day I’ll never forget,” the famous singer told reporters after the game. “What is it, like Tuesday or something?”

The Boston Red Sox used Desmond Tutu as a designated hitter on August 14, 1989 in a game against the Baltimore Orioles. Tutu struck out twice, was thrown out following a bunt and floated a single into left field. “I may be the best player ever,” he said following the game. “I rock royally, bitches!”

The 80’s pop sensation Wham! played on the Seattle Mariners in a game against the Texas Rangers on September 3, 1984. George Michael and Andrew Ridgeley shared a uniform and pinch hit rocking a grand slam homer over the centerfield fence. The Mariners tried to sign the duo to a multi-year deal but the pop stars declined. “Rockers get more chicks than ball players,” George Michael said.

Other notables who signed the is baseball were legendary center fielder and astronomer Copernicus (a surprisingly good infielder), Cher’s first husband and golden-gloved Irish rocker Bono (who had a pea shooter for an arm), and epic base stealer, director Alfred Hitchcock.

If you’d like to make a bid on this baseball, make an offer.
