"Return of the Mac," "305 J," "Parkman," "Freight Train," and "Unicorn" are a few of the nicknames that will appear on the back of D-backs uniforms during Players' Weekend, presented by Valspar Stain, and Brad Boxberger will be the first-ever MLB player to have emojis for his name on the back of his jersey. The event returns for its second year for all games scheduled from August 24-26, it was announced today by Major League Baseball and the Major League Baseball Players Association.
 
Players' Weekend will showcase the personalities and interests of Major League players by allowing them to select a nickname for the back of their jersey as well as wear and use uniquely colored and designed equipment including bats, spikes, batting gloves, wristbands, compression sleeves and catcher's equipment.
 
Players will wear specially designed uniforms created for the three games with jerseys by Majestic, caps by New Era and socks from Stance. Uniform images for each of the teams can be found here: Players' Weekend Caps and Players' Weekend Jerseys. Each player will have the opportunity to recognize someone who was instrumental in his personal development, or a baseball player who inspired him to achieve, on a jersey patch on his right sleeve. In addition, each player will have the option to wear a t-shirt highlighting a cause or charity of his choice during pregame workouts and postgame interviews.
 
Game-worn, Players' Weekend jerseys will be auctioned at MLB.com/auctions. All proceeds will be donated to the MLB-MLBPA Youth Development Foundation, a joint effort established in July 2015 by MLB and the MLBPA with an initial commitment of $30 million focused on improving the caliber, effectiveness and availability of amateur baseball and softball programs across the United States and Canada.
