PITTSBURGH -- "Redturn2," "El Titan," "Logie Bear" and the rest of the best team in the game revealed their unique personalities at Dodger Stadium Friday as Major League Baseball and the MLB Players Association hold the inaugural Players Weekend.

Players are wearing colorful, non-traditional uniforms featuring alternate designs. And instead of last names on the back of their jerseys, most players have their nicknames. Players are also wearing a special sleeve patch showing the progression of a child evolving into a Major Leaguer. Under that logo, each player has the name of a person who helped advance their career.

In addition to the nicknames and sleeve patches, players have uniquely colored and designed spikes, batting gloves, wristbands, compression sleeves and bats to use in the games. New Era has provided specially designed caps, Stance has provided socks and players will wear T-shirts during pregame workouts highlighting a charity of their choice.

Below are the nicknames the Dodgers have on the backs of their jerseys -- which will be announced on the public address system the first time through the batting order each game -- as well as the special people being paid tribute on the jersey patches:

Dave Roberts: "DOC"

"In A-ball they called me D.R., the initials, then they called me the hit doctor and shortened it to Doc," said Roberts.

Tribute patch: Dad and Butch Smith -- Roberts lost his father during Spring Training this year. Butch Smith was his high school baseball coach. "Butch Smith really mentored me and was like a second father," Roberts said. "I worked for his landscape business and he helped me understand getting a job. He's still around, and I wanted him to know what he meant to me. Outside of my family, he's the biggest Dave Roberts fan."

Luis Avilan : "AVI"

"Everybody's called me that for as long as I can remember," Avilan said.

Tribute patch: Mama y Papa -- "They've always supported for me and were at the ballpark for every game," he said.

Tribute patch: Mom and Dad -- "For their total support," Barnes said.

Cody Bellinger : "CODYLOVE"

Teammates gave it to him two Spring Trainings ago in a nod to Joclove, teammate Joc Pederson 's signature for a flurry of Valentine's Day social-media postings. It was Roberts who suggested that Bellinger needed a nickname to boost his social-media followers, which at the time numbered fewer than one thousand.

Tribute patch: Mom and Dad -- Father Clay, the former Yankees player, and mother Jennifer, "because they supported me through club-ball days and travel-ball days."

Tony Cingrani: "GRANI"

Tribute patch: Anthony Cingrani Jr. -- "That's in tribute to my Dad," Cingrani said.

Tribute patch: Mom and Dad -- "I wouldn't be here without them," Forsythe said. "I'm starting to experience that now having our first child and seeing the time and effort that goes into raising a child, the selflessness, you appreciate what they went through a little more. That's why I want to pay tribute to them."

Adrian Gonzalez : "EL TITAN"

"Eduardo Ortega, the Spanish broadcaster of the Padres, gave me that name because I went to a high school called the Eastlake Titans, and after a year or two, he took out the Eastlake and just called me El Titan," Gonzalez said.

Clayton Kershaw : "KERSH"

Tribute patch: Mom and Dad -- "I love them and everything they have done for me," Puig said.

Josh Ravin: "CUERVO"

"It means raven in Spanish," said Ravin. "Maybe it will help people understand that you pronounce it raven and not ravine."

Tribute patch: Mom and Dad -- "My dad from the get-go was always telling me how good I would be and I would tell him he didn't know what he was talking about," said Ravin. "To see it be a reality, did he really know? For many reasons, I wouldn't be here without my mom and dad."

Tribute patch: Mom and Dad -- "When I had Tommy John surgery and I decided to quit baseball, my dad said, 'Don't give up.' He and my mom have supported me in every way, including financially," Stripling said.

Chris Taylor: "CT3"

Tribute patch: Mom and Dad -- "They always supported whatever I wanted to do, and baseball was what I wanted. They bent over backwards to make it happen," Utley said.

Tony Watson: "WATTY"

"It's the standard baseball nickname -- cut your name in half and add a Y," said Watson. "Got it my first year of pro ball. I tried for Tone Ranger, from the movie, 'The Breakup.' I thought it would be creative, but it's a trademark and got shot down."

Tribute patch: Coach Peyton -- Dave Hetker -- "Dave Hekter was my Little League coach and a high school teacher and played a big part in the player I am. And coach Byron Peyton is a (Dallas Center-Grimes) high school coach that was doing the behind-the-scenes stuff to get me in the University of Nebraska and kick-started my career," Watson said.
