Michael Gary Brown (born March 4, 1959) is a former starting pitcher in Major League Baseball who played from 1982 through 1987 for the Boston Red Sox (1982–1986) and Seattle Mariners (1986–1987). He was drafted in the second round of the 1980 draft, chosen in the second round, 48th pick overall out of Clemson University. He batted and threw right-handed.
Brown reached the majors in 1982 with the Boston Red Sox, playing in part of five seasons with them before moving to the Seattle Mariners in the same transaction that brought Dave Henderson and Spike Owen to Boston. His most productive season came in 1983 with the Red Sox, when he recorded career best in wins (6), earned run average (4.67), starts (18), complete games (3) and innings pitched (104). In a six-season career, Brown posted a 12-20 record with 115 strikeouts and a 5.75 ERA in 253-2/3 innings.
Following his retirement, Brown worked with the Cleveland Indians as their minor league pitching coordinator from 1995 to 2001, and as their major league pitching coach in 2002. After that, he served as pitching coach in Japan.
As of 2013, Brown was a professional scout, based in Naples, Florida, for the Arizona Diamondbacks of Major League Baseball.
