Former Cy Young Award winner Bob Welch died Monday night in Seal Beach, California, at age 57, the Oakland Athletics announced.
The A's said Tuesday in a statement that the cause of death was unavailable.
Welch won the American League Cy Young Award in 1990 when he went 27-6 and helped the A's claim the American League championship. The 27 wins remain tied for the most in the major leagues since Philadelphia's Steve Carlton won the same number in 1972.
