Majestic Cool Base on-field style jersey. Everything is sewn on, size XL. Hand-signed by Brian Wilson (San Francisco Giants).In 2010 spring training, Wilson was asked whether or not he thought himself one of baseball's elite closers. In what would turn out to be a very prophetic quote, he replied:An elite closer is a closer who's part of a World Series win. If you get that final out in the final win of the season, then you can consider yourself elite.The lot / autograph(s) includes an official MLB Authentication hologram for authenticity purposes.Authentication: MLB Hologram
