Based on how they have been shifting so much, I see the Brewers going to SS caliber personnel playing SS, 2B, and 3B. If you think about it, against RH hitters the 2B is playing up the middle or at SS anyway and needs to make that longer throw. Scooter hasn't impressed me with that throw. Additionally, when a LH hitter is being shifted, the 3B is now in the hole at SS. Hill has done OK there, but could you imagine the slow feet of many traditional 3B covering that spot? If they continue the trend towards shifts, and it appears the Brewers like this adjustment, then you're really playing 3 SS to maximize the effect. I think Villar and Rivera fits in with Perez as an alternative. Walsh and Scooter would be relegated to reserve roles or trades.
