There isn't much I can say about this one, other than wow and pass the kleenex.  An 18-year old high school senior, dying of cancer, gets his wish -- to hit one last time in a game that matters.

From the Pittsburgh Post-Gazette:

He hasn't played in a few years, but he's called on to pinch-hit. His eyes light up at the first pitch and he puts all of his 5-foot-5, 93-pound frame into one mighty swing, making contact and sending a line drive into right field for a single -- if he can reach first base. The cancer he's been battling for almost two years has spread to his pelvis, making running nearly impossible.

The kid worries about falling as he hustles down the first-base line. When he gets to the base, he lets out with a yell. "I did it! I did it!"

Safe at first with a hit and an RBI, the kid is hugged by a crying first-base coach. The opposing pitcher takes off his glove, starts applauding and his teammates follow suit. The kid's teammates run onto the field to celebrate.  Here's the full story.
