No he won't. Name the other 20 w/o looking it up. Len Barker, Cy Young, Don Larsen, Mike Witt, Kenny Rogers, Randy Johnson, Roy Halladay, Dallas Braden, Mark Buerhle, Armando Galaraga (he was perfect that day--accept it), Tom Browning, Catfish Hunter, Koufax, David Cone, David Wells, Addie Joss... that's what I can think of off the top of my head. I know there was a no-name guy in the 20's who did it for the White Sox whose name I can't remember (but I didn't look it up because that would have been cheating). I got 16. The full list is here. http://mlb.mlb.com/mlb/history/rare_feats/index.jsp?feature=perfect_game I missed 2 guys in the 1880's, Jim Bunning, Denny Martinez, and Charlie Robertson was the guy mentioned above.
