Joey Votto is hitting like an outstanding base clogging leadoff hitter. Dusty should put him there. Two stats from Lance Mcalister:

Votto 5 for 23 (.217) with 0 HR and 1 RB in 7 postseason games in his career.

Votto has played 44 games w/ 180 plate appearances since his last HR on June 24 vs Twins. He has 0 HR and 9 RBI since June 24.

1. Votto
2. BP
3. Lud
4. Bruce
5. Rolen/Frazier
6. Hannigan
