The Giants won the National League pennant in 1989 (defeating the Chicago Cubs in the NLCS in five games), and in the post-game celebration, Dravecky's arm was broken a second time when he was running out to the mound to celebrate. A doctor examining Dravecky's x-rays noticed a mass in his arm, which turned out to be malignant. Dravecky's cancer had returned, ending his career. Eighteen days later, Dravecky retired from baseball with a 64–57 record with 558 strikeouts and a 3.13 ERA in 1,062⅔ innings. He won the 1989 Willie Mac Award honoring his spirit and leadership.
