Now that Jim Thome has returned to Cleveland for what is probably the last leg of his baseball career, his credentials for the Hall of Fame look quite strong. There was a time when a player with 500 career homeruns was a lock for Cooperstown and since Jim swatted 600+ he seems destined for enshrinement. But he played in an era in which homeruns were hit at record clips. Thome only led the league in long balls once but was typically among the league leaders in that category. Is Thome’s high career total of dingers enough to carry a player from this power-obsessed era to Cooperstown?
