Mike Flanagan was a Baltimore Oriole through and through. After playing 15 of his 18 seasons in Baltimore, he served as their pitching coach, molded the club as a front office executive, and broadcast their games. There have not been many people as affiliated with the Orioles for as long or as intricately as Flanagan.
But Flanagan’s on-field performance alone makes him one of the top Orioles of all time. In 450 games (328 starts) spanning 2,317.2 innings, he pitched to an ERA of 3.89 and a WHIP of 1.32. His ERA+ was an even 100.
