About Mike Flanagan

Baltimore gave Flanagan the Opening Day start in 1978, and he made his only All-Star team after a 12-6 first half. His 40 starts tied for the league lead, and he finished 19-15 with a 4.03 ERA over 281 1/3 innings. On September 26 he stood one out from a no-hitter at Cleveland before Gary Alexander homered. The Orioles are named on his #341 card.

Mike Flanagan was a left-handed starter who pitched for the Baltimore Orioles from 1975 to 1987, for Toronto from 1987 to 1990, and again for Baltimore in relief in 1991 and 1992. He finished 167-143 with a 3.90 ERA and 1,491 strikeouts in 2,770 innings. A seventh-round Orioles pick in 1973 out of the University of Massachusetts, he won the 1979 American League Cy Young Award with a league-best 23 victories and was a member of the 1983 World Series champions. He made 157 consecutive starts before tendonitis ended the run in September 1981. In 1991 he threw an inning of a combined no-hitter against Oakland, and in 1992 he was the last Oriole to pitch at Memorial Stadium. He was named to the Orioles Hall of Fame in 1994, then served the club as pitching coach, broadcaster and executive vice president of baseball operations. He died in 2011.
