I think I'd bat Billy first and Votto second to start off the year. I'm curious to see the dynamic of Billy leading off a game...he gets on, the pitcher is probably gonna be in a hole. And if he gets on and steals second, let the pitcher walk Votto for all I care. 2 on, no outs.
I actually want to see how pitchers pitch to Billy, for fear of walking him. Will they go right after him with fastballs?
