Right-handed pitcher Denny McLain’s major league career came to an end on March 27, 1973 when he was released by the Atlanta Braves. Only 29 years old at the time, McLain ended his ten-year career with a 131-92 career record and an ERA of 3.39. In 1968, McLain was the first 30-game winner since 1934.

Yes, abbreviated career…. His 31-game win season was in 1968.
Fixed it — thank you!! Not sure where 1970 came from.
