There have actually been a lot of ballplayers who have injured themselves while celebrating.
Kendrys Morales missed a whole season after breaking his leg stomping on home plate after a home run. Anibal Sanchez twisted an ankle after the Tigers clinched the AL central crown a few years back. Aubrey Huff sprained his knee hopping over the railing after Matt Cain‘s perfect game. Mets reliever Ramon Ramirez injured his hamstring that same year celebrating Johan Santana’s no-hitter. My favorite was the Marlins’ Chris Coghlan tearing the meniscus in his left knee while trying to give a pie-to-the-face to Wes Helms after a walkoff win.
Gotta be careful out there, even after the playing is done. Even when you’re giving high fives:
Man, the damage Buck Showalter caused last night is incalculable.
