There are quite a few seemingly arbitrary numbers that go into THON each year, and this cycle is no different. Last year, it was defined by 46 hours, 667 dancers, and $13,756,374.50 raised FTK. This time, however, the magic number is 51. THON 2023 is the 51st THON in history, and there are 707 dancers.

If you’re headed to the Bryce Jordan Center during THON Weekend, there are plenty of famous No. 51 jerseys to wear to celebrate the special (?) number.

Randy Johnson: Arizona Diamondbacks

The Big Unit retired from baseball following the 2009 season, wrapping up an incredible Hall-of-Fame career in which he won 303 games and five Cy Young awards. Johnson also made 10 All-Star teams during his illustrious 21-year MLB career. The highlight of Johnson’s career came when he was named World Series MVP as a crucial part of the Diamondbacks’ victory over the New York Yankees in the 2001 World Series.

There’s no doubt that wearing the jersey of one of the best pitchers in baseball history is a perfect way to commemorate 51 years of THON.

Ichiro Suzuki: Seattle Mariners

Another No. 51, another Mariners legend. While Johnson is best remembered for his days with the Diamondbacks, there’s no doubt as to what team Ichiro should be associated with. A career .311 hitter, Ichiro retired in 2019 after being an All-Star and Gold Glover every year from 2001 to 2010. Suzuki collected a staggering 4,367 hits split between his time in the MLB and the Nippon Professional Baseball League.

Supporting THON and one of the best pure hitters in baseball history never seemed possible, until now.

Mitchell Tinsley & KeAndre Lambert-Smith: Penn State Football

We’re getting a little creative here. There haven’t been too many notable No. 51s in Penn State football history so we’re gonna combine two recent fan favorites to create our own No. 51. Mitchell Tinsley lit up defenses in the Conference USA before he transferred to Penn State for the 2022 season. In 13 games, the route runner caught 51 passes for 577 yards and five touchdowns.

So, grab a buddy and make your own No. 51.

Dick Butkus: Chicago Bears

Yes, that’s a real name. Bears Hall-of-Famer Dick Butkus possesses one of the more iconic names in sports history, and he’s also recognized as being one of the best players in NFL history. Butkus was named to the first-team All-Pro five times in his nine-year career while being selected to eight Pro Bowls. The Chicago native was elected to the Pro Football Hall of Fame in 1979.

Wearing a Dick Butkus jersey at THON will definitely garner some attention, but any attention is good attention when it’s for a good cause.
