Don Gullett, a standout major league pitcher who played for four consecutive World Series champions in the 1970s, died on Wednesday.

He was 73.

The Cincinnati Reds, New York Yankees and Baseball Hall of Fame all paid tribute to Gullett in social media posts.

There was no information provided on his death, but the Cincinnati Enquirer reported he had recent health issues.

Gullett went 109-50 with a 3.11 ERA in nine seasons with the Reds and Yankees.

The left-hander had 44 complete games, 14 shutouts and 11 saves in 266 career games.

He was inducted into the Reds’ Hall of Fame in 2002.

“Don Gullett, the best athlete and competitor I ever saw or played with! He will be missed,” former Reds catcher Johnny Bench posted on X, formerly known as Twitter.

Gullett — a native of nearby Lynn, Kentucky — was selected by Cincinnati in the first round of the 1969 amateur draft.

He was 19 when he made his major league debut in April 1970 — with Bench behind the plate.

Gullett helped Cincinnati win the World Series in 1975 and 1976, going 26-7 for the Big Red Machine — with a 2.68 ERA and 12 complete games in 45 appearances combined over those two seasons.

He then signed with New York in free agency, and the Yankees won it all in 1977 and 1978.

He went 18-6 with a 3.59 ERA in 30 starts during his two years with New York.

Gullett retired after the 1978 season.

He went on to coach in the Reds organization.

“Don dedicated 24 years to this franchise as a player, coach and minor league instructor,” Reds owner Bob Castellini said in a team post on X. “An anchor on the pitching staff of one of the greatest baseball teams in history, his contributions to our rich tradition, our city and his community will never be forgotten.”
