Ben Zobrist doesn't garner a lot of attention. He was a modest sixth-round pick in the 2004 draft and was once part of a trade for the immortal Aubrey Huff. Since arriving in the majors, he's never led the league in any offensive category, save the league-leading 12 sacrifice flies in 2010. His career batting average is .258. He doesn't make highlight-reel defensive plays. He steals 15 to 20 bases per season, knocks roughly the same number of home runs and draws more than his fair share of walks. Despite this seemingly modest profile, Zobrist might be the most important figure in the American League playoff race.
