Ronald Gene Davis (born August 6, 1955) is an American former Major League Baseball pitcher who played 11 years from 1978 to 1988.

While in New York he was used as the team's closer after an injury to All-Star relief pitcher Rich Gossage from a fight with teammate Cliff Johnson.

During the 1981 Major League Baseball strike, Davis worked as a waiter at a restaurant of the Hyatt Regency Hotel in Kansas City.

[2] In April 1982, Davis was traded to the Minnesota Twins, along with Greg Gagne, and Paul Boris in exchange for Roy Smalley.

Among Twins fans, with whom he came to be known as Ron "Boom-Boom" Davis, his name is still synonymous with ineffective relief pitching, despite finishing in the top five for saves in the American League in three of his five seasons with the team.

After hitting the first batter he faced, Davis eventually loaded the bases and allowed the game-tying run to score by throwing a wild pitch.

Davis pitched for the Sun City Rays of the short-lived Senior Professional Baseball Association in 1990.
