On Wednesday, MLB umpire John Tumpane was walking across the Roberto Clemente Bridge in Pittsburgh, just outside PNC Park, where Trumpane would later work the Rays-Pirates game (TB-PIT GameTracker). Tumpane happened upon a woman standing on the outside of the railing and staring down into the waters of the Allegheny River.
Here's part of what happened next, via Stephen J. Nesbitt of the Pittsburgh Post-Gazette:
The bridge was mostly empty at that time of day. Tumpane rushed toward the woman, who appeared calm, and asking what was going on.
"I just wanted to get a better look of the city from this side," she replied, according to the umpire's recollection.
