Elijah Jerry "Pumpsie" Green (October 27, 1933[citation needed] – July 17, 2019) was an American Major League Baseball (MLB) infielder who played with the Boston Red Sox (1959–62) and New York Mets (1963).

Green had the distinction of being the first black player to play for the Red Sox, the last pre-expansion major-league club to integrate.

In his Boston tenure, he was used mostly as a pinch runner or day-off replacement for infielders Pete Runnels and Don Buddin.

[3][4] Green made his MLB debut on July 21, 1959, against the Chicago White Sox at Comiskey Park, entering the game in the top of the eighth as a pinch runner for Vic Wertz and playing shortstop in the bottom of the eighth and becoming the Red Sox's first black player.

[7] That same day, pitcher Earl Wilson made his MLB debut, becoming the Red Sox' second black player.

Despite a hot start to the season, Green developed appendicitis in Washington, D.C. in May, which put him out of the lineup for about four weeks and kept him from playing at full strength for even longer.

Conley was not spotted until three days later by a New York Post sports reporter at the Idlewild International Airport trying to board a plane for Israel, with no passports or luggage.

[9] After the 1962 season, Green was traded to the New York Mets along with Tracy Stallard and Al Moran in exchange for Felix Mantilla.

[3] In a five-season major league career, Green was a .246 hitter with 13 home runs and 74 RBI in 344 games.
