22. Troy Tulowitzki (2008)
Tulowitzki found himself on the Rockies 15-day disabled list after a ridiculous self-inflicted injury. The Colorado star returned to action after missing 46 games with a torn thigh tendon. But he did himself no favors upon his return. The hitter smashed his bat against the ground in frustration but it shattered and cut his hand. It was a frightening moment for the sophomore.

There was also an ongoing investigation into maple bats. This was because they appeared to have a higher tendency to shatter than their ash equivalents. Furthermore, it continued Tulowitzki’s frustrating season after helping the franchise to a World Series win. He required 16 stitches on his hand because the cut was so big (via ESPN). It was a harsh lesson for the Rockies star.
