34. Most No-Hitters (7)
Set By: Nolan Ryan
It would seem that a relatively modest total like seven no-hitters would be catchable, but what you have to consider is how difficult it is to throw one in the first place. In baseball's modern era (since 1901), there have been a total of 236 no-hitters thrown. The only active pitchers who have thrown two no-hitters are Roy Halladay, Mark Buerhle, and Justin Verlander. While Verlander does have an outside shot at Ryan's record, the more potent offenses of this current era make it exceedingly unlikely he'd be able to throw five over the rest of his career.
