If interested, should be a cheap way to own a ball that was pitched by the greatest closer and postseason pitcher in the 9th inning of a playoff game where he picked up his 40th career postseason save.
Very rare to find MLB Authenticated balls pitched by Rivera. Get it signed and you have something very valuable!!
