Done and Dunn
There have been eight players in the history of baseball that have had 5 consecutive seasons with 40 or more home runs. There have been 3 with 6 or more, Babe Ruth being the only with no ties to performance enhancing drugs. The other two, Alex Rodriguez and Sammy Sosa, achieved this for 6 consecutive seasons, and Babe Ruth for 7.
When Adam Dunn hits 3 more home runs he will become just the fourth player to hit 40 home runs for 6 straight seasons, and the first to do so with 6 straight seasons of 20 or more doubles and 100 or more walks.
Alex Rodriguez and Sammy Sosa achieved 40+ home runs 6 straight years. A-rod only achieved 100 walks once and Sosa only twice. And Sosa hit 20 plus doubles in only 5 of 6 years. Ruth, who still remains king with 7 straight seasons of 40 or more home runs, hit 20 plus doubles and 100 walks in 6 only of 7 seasons.
