Donnie Ray Moore (February 13, 1954 – July 18, 1989) was an American relief pitcher in Major League Baseball (MLB) who played for the Chicago Cubs (1975, 1977–1979), St. Louis Cardinals (1980), Milwaukee Brewers (1981), Atlanta Braves (1982–1984) and California Angels (1985–1988).

Moore is best remembered for the home run he gave up to Dave Henderson while pitching for the California Angels in Game 5 of the 1986 American League Championship Series.

With only one more strike needed to clinch the team's first-ever pennant, he allowed the Boston Red Sox to come back and eventually win the game.

Moore remained in the game for the Angels; he was able to stifle a tenth inning Red Sox rally by getting Jim Rice to ground into a double play.

"[3] Moore was battling a shoulder injury at the time of the 1986 American League Championship Series and was never able to remain injury-free afterward.

He signed with the Kansas City Royals for the 1989 season, but played only in the minor leagues before being released in June of that year, ending his 14-year career in baseball.

[4] Back inside the house, still in the presence of at least one of his sons, Moore then put the gun to his head and committed suicide.
