Is Mauer 100%?

I know it's a small sample size and all that, but has anyone else noticed that Joe Mauer does not look sharp at first base? I haven't seen every televised spring game so far, but the games I have seen have often included a Mauer error at first and/or not quite getting to or handling balls that are playable. His two run error today gave the game to Pitt when a simple pickup and step on the bag would have preserved a 1-0 win for the Twins.

I guess after Morneau's lingering effects from his concussion injury, I am beginning to wonder if Joe is 100% yet? Maybe 90%, or something else, but right now I think Colabello is playing better defense at first than Joe. Thoughts?
