She gave him her kidney, then he asked for her heart.

Just months after Taesha Benson donated one her kidneys to her boyfriend, Travis Spire-Sweet, their touching story earned them a chance to throw out the first pitch a Kansas City Royals game.

But Spire-Sweet also threw Benson a curveball.

On bended knee, he proposed to her on the field of Kauffman Stadium on May 28.

Spire-Sweet, who was born with chronic kidney problems and wasn't expected to live past his first birthday, spent more than a year on a donor's list before discovering Benson was a perfect match, an only 1-in-30,000 chance.

"I thought it was a good time to thank the person who saved my life, and hopefully have the rest of my life to thank her for what she did," Spire-Sweet told local affiliate, KSHB.

Through tears of joy, Benson said "Yes," removing the baseball glove from her left hand so he could place the ring on her finger.

Spire-Sweet decided it was the perfect opportunity to pop the question because the couple went to a Royals game on their second date.
