OAKLAND -- A's reliever Blake Treinen hears fans call him "B-Lockay" all the time, referencing the famous "East/West College Bowl" skit from "Key & Peele."
But Treinen admitted, "If it wasn't for playing baseball, I probably would have never seen that skit."
Treinen will wear B-Lockay for three days during the inaugural Players Weekend being introduced by MLB and the MLB Players Association.

Treinen said he's liked the skits from the show that he's seen, but he doesn't search for them on his own, adding, "I see them from guys in the locker room." But like so many, he and former Nationals teammate Aaron Barrett found humor in how their names were pronounced in the "East/West College Bowl" skit and have called each other A-A-Ron and B-Lockay since.
From Aug. 25-27, all players will wear colorful, non-traditional uniforms featuring alternate designs made by Majestic Athletic. The players had the option of putting a nickname on the back, with Treinen saying the most difficult part for him was figuring out how to spell his.
"They don't spell it out for you in the skit, they just say it. I didn't know what to do," Treinen said. "It could Buh-Lockay, and I was like, 'Nah, that was too much.' So I went with B-Lockay. Keep it simple."
Players will wear and use uniquely colored and designed spikes, batting gloves, wristbands, compression sleeves, catcher's masks and bats, as well as specially designed caps by New Era and unique socks from Stance. During pregame workouts and postgame interviews, they will wear T-shirts highlighting a charity or cause of their choice.

Also, each player will wear a special patch on his sleeve showing the progression of a child evolving into a Major Leaguer. Under that logo is white space, and every player will mark a name of a person who they are grateful to for helping them advance their careers, such as a coach or family members.
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.
