One of the rarest feats in the sport of baseball has occurred just 12 times in the history of the majors – the unassisted triple play. Four of those improbable players have signed this baseball with the date that they executed their triple play: Bill Wambganss – Oct. 10, 1920; James Cooney – May 30, 1927; Johnny Neun – May 31, 1927; Ron Hansen – July 30, 1968. Cooney’s signature is light, Hansen’s is NRMT, Neun is very dark, Wambganss is EX. Unofficial ball is EX-MT.
