It is completely normal for April, lots of popouts, lots of foulballs and a lot of hard hit balls that don't leave the yard that probably would have mid season. Players take a couple weeks to get their timing down. Right now there are 30 players who have 30% or higher of their flyballs being in the infield, including guys like Mauer who are legit high average hitters. Last year the highest qualified player was Eric Byrnes at 26.7%. Second highest was Wells at 19.1, third was Weeks at 17.4.
