5. Dick Allen
Should-be Hall of Famer Dick Allen had double-digit home-run seasons in 13 of his 15 years in the majors, and the only two seasons in which he didn’t were when he played fewer than 60 games.
After not hitting a single home run in his brief 10-game 1963 debut, Allen hit 29 home runs in his real rookie season in 1964 and won Rookie of the Year. Between 1964-69, he hit .300 with 177 home runs in 856 games.
When Allen returned to the Phillies in 1975, he hit another 27 home runs over the following two seasons, bringing his franchise grand total to 204.
