Scott Podsednik led the National League in stolen bases with 70 in 2004. He swiped 59 to pace a productive Chicago White Sox lineup to a World Series title in 2005. For his career, Podsednik stole 309 bases.
He demonstrated the value of a good leadoff man in his first full season in 2003 by scoring 100 runs for the Milwaukee Brewers.
So even at 41, retired for a half-decade and serving as a White Sox pre- and post-game analyst on CSN Chicago, Podsednik should be an authority on speed and proper base running techniques.
