About A. Bartlett Giamatti
Angelo Bartlett "Bart" Giamatti ( JEE-ə-MAH-tee; April 4, 1938 – September 1, 1989) was an American professor of English Renaissance literature, the president of Yale University, and the seventh commissioner of Major League Baseball. Giamatti served as Commissioner for only five months before dying suddenly of a heart attack. He is the shortest-tenured baseball commissioner in the sport's history and the only holder of the office not to preside over a full Major League Baseball season. Giamatti's most notable act as Commissioner was to negotiate the agreement resolving the Pete Rose betting scandal in which Rose was permitted to voluntarily withdraw from the sport to avoid further punishment. Fay Vincent, Giamatti's close friend and baseball's first deputy commissioner, became acting commissioner upon Giamatti's death, and was quickly elected by MLB owners to succeed Giamatti as the new commissioner. Son Marcus Giamatti threw out the first pitch before the game. He became the second baseball commissioner to die in office, the first being Kenesaw Mountain Landis in 1944.
