Players Weekend was an annual Major League Baseball (MLB) event held from 2017 to 2019 in which players on all 30 MLB teams wore colorful baseball uniforms based on youth sports designs and sported nicknames on the back of their jerseys during regular season games. The league also relaxed the rules for cleats, batting gloves, wristbands, compression sleeves, catcher's masks, and bats, allowing players to use custom-designed gear. The multi-day event was designed to give players the opportunity to express their personal style, appeal to the youth demographic, and acquaint hometown fans with newer team members.
