[Giants]

I watched a truncated replay of Matt Cain's perfect game, and Chris Heston's no-hitter. Heston's career record was 13-13, and he threw a no no. Old timers might remember Ed Halicki, owner of a 55-66 record, who threw a no hitter. Most of the Giants' pitchers who threw no-hitters are very well recognized (Mathewson, Marquard, Hubbell, Rusie, Marichal, Wiltse, Tesreau, Barnes, LIncecum, Cain, Montefusco, Perry).

Who was the worst pitcher to ever throw a no-hitter? Who was the worst to throw a perfect game?

Conversely, who were the best pitchers to never throw a no-hitter (minimum, 200 wins)?

I was at the Ed Halicki no-no (v. the Mets).  There was a controversial official scorer’s ruling on a ball hit to Felix Millian.  He made a nice stop but couldn’t complete the play.  It was close enough to rule an error.  

Len Barker “worst” to throw a perfecto?
