Raymond Roger Miller (April 30, 1945 – May 4, 2021) was an American pitching coach[1] and manager in Major League Baseball (MLB).

[3] In his final season at Rochester, he was a player-coach, and then became minor league pitching instructor for the Red Wings' parent club, the Orioles, from 1974–77.

But in January 1978, the Orioles' pitching coach position opened unexpectedly when George Bamberger was named skipper of the Milwaukee Brewers.

[7] He worked under managers Earl Weaver and Joe Altobelli and coached for O's teams that won the 1979 American League championship and the 1983 world title.

[4] Miller subsequently returned to the coaching ranks, spending ten seasons as pitching mentor of the Pittsburgh Pirates (1987–96) working for Jim Leyland and one (1997) back in Baltimore under Davey Johnson.

When Johnson resigned at the close of the Orioles’ AL East Division championship season, Miller replaced him as manager.
