Most of the top OPS+ players have been to multiple All-Star games.  I believe that in the top 20 only Bobby Abreu and Brian Giles have gone twice and that is the fewest of that group.

The best OPS+ player to never make an all-star game is JD Drew.  Might have to do with injuries or maybe just a bad stigma.  His OPS+ is 130, tied with Adam Dunn for 22nd among active players.  The next on that list...you got it, Pat Burrell.  Tied for 34th with Derek Jeter with an OPS of 121.  Of course, Jeter is attending his 9th all-star game.  Go figure.  Just makes you realize how unsupportive we are as fans.
