Claim: Bob Allison was a Major League Baseball outfielder who debuted in 1958 and was voted Rookie of the Year in 1959 before hitting a slump the next year.
Evidence: William Robert "Bob" Allison (July 11, 1934 – April 9, 1995) was born in Raytown, Missouri and was a Major League Baseball outfielder and right-handed batter who played in the American League for the Washington Senators / Minnesota Twins from 1958 to 1970. On September 16, 1958, Allison made his major league debut, batted lead-off, and got a single in four at-bats in a 5–1 loss to the Cleveland Indians. In 1959, Allison went north with the Senators and he batted .261 with 30 home runs and 85 runs batted in; led the league in triples (9), was named to the All-Star team, received a smattering of MVP votes, and was honored by being voted Rookie of the Year. Allison experienced a "sophomore slump" in 1960 with an across-the-board drop in his offensive statistics.
