In 1988, pitcher Dave Stewart compiled the MLB record for most balks in a season at 16.  To this day this record still stands.  

There are 2 Fulls graded by PSA, but ZERO stubs.    So fairly scarce for this oddball MLB record.  

See my other auctions for rare & historic tickets

(only ticket stub is for sale here, the other pix were just taken from the internet)
