Is Buster Posey for Real?

A baseball post.  As fans know, Buster Posey has been on a tear for the San Francisco Giants, with an 18 game hitting streak.  Is he really that good?

Checking his stats for the last ten days, you get the following:  (your stats may differ if you check a different day than today)

41 at bats, 18 hits, 1 HR, 3 walks and 6 Ks.  Walks don't count as "at bats".  In 41 at-bats, he struck out 6 times, and hit 1 home-run.  Which means that he put the ball "in play" 34 times.

Of his 18 hits, 1 was a home run, so that means that, on his "in play" balls, he got 17 hits.

  There's a stat for that of course, BABIP.  (note - the stat also involves sac flies, of which I don't have the numbers)  Posey's BABIP is a cool .500.  A typical BABIP is .300.

Some BABIP can be attributed to great speed on ground balls, which doesn't apply to Posey, or to a greater ability to hit line-drives.  He showed a bit of the later in the minors.  However, seems like he's also been very lucky to have a BABIP 66% higher than league average.
