Soiled and game prepared "muddied" baseball as used in Nolan Ryan's seventh and final career no hit game played on May 1, 1991. The ball has been signed by Ryan across the sweet spot in black ink adding date of "5-1-91". Additional notation of "#7" is written in unknown hand. Incredibly, at the age of 44 Nolan Ryan tossed his record setting seventh no hit game against the Toronto Blue Jays on May 1, 1991. The ball was retained from game play that day by American League Umpire John Shulock and was signed by Ryan accordingly.
