For Tennessee's Steve and Heather Winfree, baseball cards represent a type of stress relief—a hobby for them to enjoy together. In fact, Heather often brings home packs for them to open together, so nothing seemed out of the ordinary when she presented Steve with a new pack last week.

"There were a lot of times where he would be in the hospital and I would grab a pack and we would open them," Heather explained to "The low-key fun gets our minds off of the everyday stresses."

Although he was a little suspicious when she started filming, he quickly dismissed it, and dove into the new pack. The Atlanta Braves fan was pleased with the haul. Heather recorded her excited husband as he flipped over a Mike Trout card and then a Platinum Presence Clint Frazier. Then he came across a card with his own photo on it and the word "recipient" where a player's position was usually located. Steve, who has been on dialysis since November, was getting a new kidney and his wife Heather was his match.

"I saw it coming," he told "But I lost it and I asked her, 'You want to save my life?'"

Heather told she felt guilty for not telling Steve the moment she found out she was a match. "We were really stressed out during the week with everything going on," she said. "But I didn't want to break the news to him over the phone or anything."

First, Heather has to undergo additional tests to make sure she's healthy enough for the surgery, and if all goes according to plan, the surgery should take place by the end of the month, reports
