One of the earliest Ken Griffey Jr. photo-matched items known, this superb piece is from the 1992 Home Run Derby in which Junior finished second. Royal blue mesh top has yellow trim with Mariners' M's baseball logo patch on left breast, zip collar, and number 24 stitched on back in yellow; Majestic size XL tag is in collar. Great use is shown including wear and loose threads. Originally purchased directly from the Mariners in January 1993, right after the 1992 season ended, our consignor purchased the item from Ball Four Sports a few months later and included is a photo of the ad Ball Four put out which lists "1992 Seattle Mariners Blue Warm-Up Jerseys" with Griffey's name and size XL listed below. Griffey's seven homers were enough to take 2nd in the American League Home Run Derby in '92, finishing behind a young Mark McGwire of the Oakland A's, who bashed 12.
