Scott McGregor (left-handed pitcher)

In 2002, McGregor returned to baseball as a pitching coach in Class A ball, and began working his way up. He was named interim Orioles bullpen coach in late 2013 replacing Bill Castro, who was promoted to pitching coach. He did not return in 2014.

After his playing career, he became a youth pastor before returning to serve a major league coach. He was most recently the pitching coach for the Aberdeen IronBirds. In 1990, McGregor was inducted into the Baltimore Orioles Hall of Fame.

In the 1983 postseason, McGregor allowed only two runs in the openers of the ALCS and World Series, but lost both games by scores of 2–1 to the White Sox and Phillies, respectively. However, in Game 5, he shut out the Phillies in a complete game to end the series, four games to one. He remained a starting pitcher on the Orioles for the next five seasons, and made his final appearance on April 27, 1988.

McGregor was an integral member of the Orioles team that won the 1983 World Series, pitching a complete game shut out to clinch the series victory. Known for constantly changing the speeds of his pitches, McGregor was a 20-game winner in 1980 and was named an American League (AL) All-Star in 1981.

McGregor was solid in two postseasons with the Orioles in 1979 and 1983. McGregor sent the Orioles to the World Series by clinching the 1979 ALCS with a Game 4 shutout of the California Angels. He pitched a complete-game victory in Pittsburgh in Game 3 of the World Series. Despite taking the loss in Game 7, McGregor yielded two runs in 8 innings to Willie Stargell and the eventual champion Pirates.

McGregor was acquired along with Rick Dempsey, Tippy Martinez, Rudy May and Dave Pagan by the Orioles from the Yankees for Ken Holtzman, Doyle Alexander, Elrod Hendricks, Grant Jackson and Jimmy Freeman at the trade deadline on June 15, 1976. He, Dempsey and Martinez became part of a nucleus that kept the Orioles as perennial contender for the next decade. He was selected to the American League All-Star team in 1981. He won 20 games in 1980. "The kid can pitch, that's all I can say," praised Hall of Fame manager Earl Weaver after McGregor threw a shutout on June 24 of that year.

Born and raised in Southern California, McGregor played baseball at El Segundo High School with Baseball Hall of Fame member George Brett, who was a year ahead. He was the 14th overall selection in the first round of the 1972 Major League Baseball draft by the New York Yankees.

Scott Houston McGregor (born January 18, 1954) is an American former professional baseball player and coach. He played his entire career in Major League Baseball as a left-handed pitcher for the Baltimore Orioles from 1976 to 1988.
