Tim Andrews, Massachusetts General Hospital’s second patient to undergo a pig kidney transplant, threw out the first pitch at the Boston Red Sox game at Fenway Park on June 16, 2025. He was joined by his wife, Karen, other family and members of his care team. The occasion signified a major milestone — 137 days since his surgery in January, making him the longest living recipient of a pig kidney.
