A native of Oriskany Falls, New York, at the age of 20, Spooner was signed to a contract by the Brooklyn Dodgers as an amateur free agent in 1951 and was assigned to play in Minor league baseball. Spooner's early minor league career was promising, but erratic. Walks were frequently a problem, as Spooner averaged a walk per inning in his first two minor league seasons. However, he also had great speed, and showed flashes of brilliance. He made his way up the Dodgers' minor league system, compiling a fairly unimpressive 27–36 record during his first three seasons. He had a breakout year in 1954 when he won 21 games with 262 strikeouts in 238 innings for the Fort Worth Cats of the Texas League. His successful performance earned him a promotion to the Brooklyn Dodgers with one week left in the 1954 season. Spooner made his major league debut with the Dodgers on September 22, 1954 at the age of 23. He allowed only 3 hits, all singles and, struck out 15 batters, setting a Major League Baseball record for most strikeouts by a pitcher in his major league debut. He broke the record of 13 strikeouts set by the New York Giants’ Cliff Melton on April 25,. J. R. Richard tied the record in his major league debut in. Spooner also set another record for pitching debuts by recording six consecutive strikeouts, striking out the side in both the 7th and 8th innings. Pete Richert is the only other pitcher to strike out six consecutive batters in his Major League debut. Four days later, Spooner beat the Pittsburgh Pirates, 1-0, striking out 12 and surrendering 4 hits. Although he only started two games for the Dodgers, Spooner, compiled two complete gameshutouts, throwing 18 innings, giving up 7 total hits and no runs. His 27 strikeouts in two successive games was a National League record and was second only to Bob Feller’s 28 on the major league list. However, during spring training prior to the 1955 season, Spooner entered a game without warming up properly. A severe arm injury was the result, after which Spooner was out of action until May 15, then made a comeback, appearing in 29 games with the Dodgers that year, but with only fairly mild success. Initially used as a spot starter, Spooner was moved to the bullpen after two poor starts. He was added back into the rotation in late June, removed from it at the end of July, and was then given some spot starts in August and September, finishing the season at 8–6. He appeared in his final major league game on October 3, 1955 when he started game 6 of the 1955 World Series. Despite the winning record, Spooner was deemed only marginally effective. Prior to the injury, Spooner threw a fastball which ranged in the mid to high 90s; post-injury, that was not the case. In his final appearance with the Dodgers, Spooner started game 6 of the 1955 World Series, and was shellacked, giving up 5 runs in one-third of an inning, taking the loss. Spooner never again played in the majors. Still hampered by injuries, he pitched in only 4 games in Triple-A in 1956, was later called up to the Dodgers in September, although did not get into any games that year. For the 1957 season, Spooner was demoted all the way back down to A-ball: in 13 games he was 2–4. The Dodgers left Spooner unprotected in the 1957 minor league draft, and he wound up being claimed by the St. Louis Cardinals. For the 1958 season, Spooner was demoted to the very lowest rung of minor league ball, playing for Dothan in the 'D' level Alabama–Florida League, appearing in 9 games. He also played two games for Houston at the AA level that same season, but that ended his professional career. Spooner attended spring training in 1959, but retired before the season started.
Later life
As his baseball career wound down, Spooner, a native of New York state, moved to Vero Beach, Florida and found work as a manager in the citrus industry. He worked at this job for the rest of his life, raising five children with his wife Carol. Spooner died of liver cancer in 1984, aged 52.
