Players will wear colorful, non-traditional uniforms featuring alternate designs. And instead of last names on the back of their jerseys, both players will have their nicknames -- Redturn2 for Turner, Codylove for Bellinger.
Players also will wear a special sleeve patch showing the progression of a child evolving into a Major Leaguer. Under that logo, each player will put the name of a person who helped advance their career. Turner will have the name of his Grandpa Bates, Bellinger will have his mother and father.
As for the nickname, Turner said his originated as his first social-media tag when he came up with the Mets in 2011.
"My nickname was always Red growing up. I played second base, and with the Mets I wore No. 2," he said. "On the sleeve, it's Grandpa Frank Bates. He never missed a game. He'd take me on vacation to the lake, but he'd make me catch 50 tennis balls before we ate dinner."
Bellinger's nickname is a little more complicated. Teammates gave it to him two Spring Trainings back in a nod to Joclove, teammate Joc Pederson's signature for a flurry of Valentine's Day social-media postings. It was manager Dave Roberts who suggested that Bellinger needed a nickname to boost his social-media followers, which at the time numbered fewer than 1,000.
"I tried doing #Codylove for the jersey, but they don't allow hashtags," Bellinger said. "My name in the clubhouse is always Belly, but I went with Codylove."
The sleeve patch salutes his parents, father Clay, the former Yankees player, and mother Jennifer, "because they supported me through club-ball days and travel-ball days."
In addition to the nicknames and sleeve patches, players will have uniquely colored and designed spikes, batting gloves, wristbands, compression sleeves and bats to use in the games. New Era will provide specially designed caps, Stance will provide socks. Players will wear T-shirts during pregame workouts highlight a charity of their choice.
Game-worn Players Weekend jerseys will be auctioned at MLB.com/auctions with 100 percent of net proceeds 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 U.S. and Canada.
The uniforms will first be worn by the Pirates and Cardinals during the MLB Little League Classic to be played in Williamsport, Pa., on Aug. 20 during the 2017 Little League World Series. That game will take place at Bowman Field, home of the Williamsport Crosscutters, a Phillies affiliate in the short-season Class A New York-Penn League.
