Third baseman Pedro Alvarez has switched his jersey number from No. 17 to No. 24.#pirates— Pirates (@Pirates_Former) December 16, 2010
Or does this mean that you keep them as a collector's item? Either way, Alvarez isn't wearing 17 anymore. With Delwyn Young out of the picture he's taking his minor league number 24 back. If you have an old Brian Giles jersey laying around all you have to do is change the name (and add sleeves).
