Bud Selig’s long tenure as commissioner of baseball has been marked by ups and downs. This week saw another low point with the first-ever MLB All-Star Slam Dunk Competition.

Only one contestant was able to successfully dunk, Twins catcher Joe Mauer – a former high school basketball star – but he tweaked his knee upon landing when his cleats caught in the grass. Several other All-Stars were injured, too, claiming everything from hamstring pulls to exhaustion.
