Robert Bush Sebra (December 11, 1961 – July 22, 2020) was an American professional baseball pitcher, who played in Major League Baseball (MLB) for the Texas Rangers, Montreal Expos, Philadelphia Phillies, Cincinnati Reds, and Milwaukee Brewers, in all or part of the 1985 to 1990 seasons. He threw and batted right-handed.^[1]

Sebra attended the University of Nebraska–Lincoln, and in 1981 he played collegiate summer baseball with the Wareham Gatemen of the Cape Cod Baseball League.^[2] He was drafted by the Texas Rangers in the 5th round of the 1983 Major League Baseball draft.

Over the course of his big league career, he pitched in 94 games, 52 of them as a starting pitcher. Included among Sebra's MLB highlights are 2 shutouts, a 1–0 and a 2–0, accomplished while with Montreal.^[3]

In 1986, Sebra was the last pitcher ever to give up a walk-off win where the winning run was scored by the other team's manager.^[4]

Sebra was primarily a starting pitcher but on July 28, 1989, he picked up his lone career save. He pitched a scoreless 17th inning to close out a 4-2 Reds victory over the Braves.^[5] He was traded along with Ron Robinson from the Reds to the Brewers for Glenn Braggs and Billy Bates on June 9, 1990.^[6]

The last pitch he ever threw in the majors ignited a major brawl between the Brewers and Mariners on June 30, 1990. He would receive a 5-game suspension, but not until he had already been sent down to the minors.

Born in Ridgewood, New Jersey, Sebra played prep baseball at Gloucester Catholic High School.^[7] Sebra died at the age of 58 on July 22, 2020, after spending a year in intensive care in Jackson Memorial Hospital in Miami, Florida, as a result of multiple organ failure.^[8] He had undergone a liver transplant several years earlier.^[9]
