A key member of the 1970s Cincinnati Reds dynasty has died this week.

The Reds announced on Wednesday that former lefty pitcher Don Gullett has died at the age of 73. No cause of death was given.

Gullett pitched for the Reds from 1970-76. He was on the pitching staff for Cincinnati’s back-to-back World Series victories in 1975 and 1976 and also posted multiple top-seven Cy Young finishes as a Red. The team would win four pennants and have six 95-plus-win seasons during Gullett’s time there.

After leaving Cincinnati as a free agent, Gullett then won two more World Series rings as a member of the New York Yankees in 1977 and 1978 (though he was injured for their 1978 run and didn’t pitch at all in the playoffs). He retired after the 1978 season with a 109-50 career record and a 3.11 ERA.

In the 1990s, Gullett returned to the Reds as their pitching coach. He served in that position for more than a decade (from 1993-2005) and was inducted into the Reds Hall of Fame in 2002.
