There are first impressions, and then there is what Miguel Olivo did in just his 12th game in a Rockies uniform.

The veteran catcher, who inked a one-year deal with the Rockies in January, was in an uncomfortable position during the Rockies' game against the Diamondbacks on Monday. As The Denver Post reported, Olivo passed a kidney stone in the eighth inning.

Rather than sit out as most mere mortals would, Olivo exited the bathroom, grabbed his catching gear and finished the game.

Olivo insisted that despite evidence to the contrary, he's not superhuman.

"Believe me, it’s not fun," Olivo told the Post. "Sometimes, when I’ve got that thing, I just want to die. But I can handle pain a little bit. Once it's gone, I'm normal, I'm good. Let's play baseball."

Olivo is hitting .314 with five homers already this year, which is all well and good, but he's bringing a new meaning to "doing the things that don't show up on the stat sheet."
