Question: Which team had been around longest when Burnside began his professional career? Passage:Burnside's professional career began in 1949 (he attended Dartmouth during his offseasons) and was interrupted by United States Army service in 1953. A stellar 1955 season in the Double-A Texas League, where he posted an 1811 record and 2.47 earned run average for the Dallas Eagles, earned him his first big-league call-up to the New York Giants. He started two late-season games. In his first, on September 20, he issued six bases on balls and allowed seven runs (only two of them earned) in 3 innings against the cellar-dwelling Pittsburgh Pirates. While the Giants' offense bailed him outBurnside departed the game with New York leading 117his early exit kept him from claiming the victory in an eventual 148 Giants' triumph; that went to relief ace Hoyt Wilhelm. In his second start a week later, however, Burnside threw a complete game, seven-hit victory over the Philadelphia Phillies.
