Carlos Asuaje: "CARL"
Colten Brewer: "BREWSKI"
Jose Castillo: "BIG DUDE"
At 6-foot-5, 246 pounds, Castillo is, indeed, a big dude.
Franchy Cordero: "CORDY"
Alex Dickerson: "DICKERSON"
A.J. Ellis: "DAD"
At 37, Ellis is the oldest Padre, and his teammates casually refer to him as "the dad of the team." That being said, none actually call him "Dad," though he is a father of three.
Robbie Erlin: "BOB"
Freddy Galvis: "TOCO"
Galvis' older brother began calling him Toco when the two were young. In his hometown of Punto Fijo in Venezuela, the nickname stuck. "Everyone there calls me it," Galvis said.
Austin Hedges: "HEDGEY"
Eric Hosmer: "PAPO"
A Cuban term of endearment akin to "Dude," Hosmer paid tribute to his Cuban roots with his Players' Weekend nickname. He wore the same name in Kansas City last season.
Travis Jankowski: "FRED"
The speedy Padres outfielder grew watching Mr. Rogers' Neighborhood. He watched it nearly every day, to the point where his brothers began calling him Fred for Fred Rogers. It stuck, and his teammates still call him Fred to this day.
Brett Kennedy: "KENNEDY"
Dinelson Lamet: "EL FLACO"
Lamet was skinny as a child, and the word skinny literally translates to "flaco." The nickname was given to him by a childhood friend.
Eric Lauer: "GOMER"
Gomer Pyle was character on "The Andy Griffith Show." When Lauer was a kid, his dad gave him the nickname, though no one's called him Gomer in years.
Walker Lockett: "LOCKETT"
Joey Lucchesi" "JOEY FUEGO"
Lucchesi's college teammate at Southwest Missouri State dubbed him "Joey Fuego" while trying to think up a creative nickname for Lucchesi's Twitter handle. That nickname stuck through the Minors, and Lucchesi occasionally goes by "Fuego" in the Padres' clubhouse.
Manuel Margot: "YOANDRY"
Yoandry is a family nickname he's had for years, to the point he can't remember when they first began using it. It's stretched into the Padres' clubhouse, though it isn't used regularly.
Phil Maton: "SPIN RATE"
The spin rate on Maton's fastball ranks sixth in the Majors among pitchers who have thrown at least 200 of them. It's unquestionably one of Maton's strengths -- and now, his nickname, too.
William Myers: "WIL"
Bryan Mitchell: "MITCH"
Jacob Nix: "NIX"
Luis Perdomo: "EL CHAMAQUITO"
After Perdomo was selected in the Rule 5 Draft in 2015, his teammates began calling him "Chamaquito," which loosely translates to "youngster." At the time, he was making the jump from Class A Advanced to the Majors. In his third big league season, Perdomo is still only 25, so the name still fits.
Jose Pirela: "AGUILA NEGRA"
Pirela plays winter ball for Aguilas del Zulia in Venezuela, where the team's announcer has taken to calling him Aguila Negra, which translates to Black Eagle.
Hunter Renfroe: "FROE"
Franmil Reyes: "LA MOLE"
Reyes was dubbed "La Mole" -- or "The Beast" -- by his teammates in the Dominican Summer League in 2012. Easy to see why. At 6-foot-5, 275 pounds, Reyes boasts otherworldly power. Despite his sporadic playing time this year, he's hit three homers 440 feet or further -- one of only eight National Leaguers to do so.
Clayton Richard: "CLAY CLAY"
Cory Spangenberg: "SPANGY"
Craig Stammen: "TRIG"
Trigger was a nickname given to Stammen by one of his friends' fathers. Over the years, it was shortened to Trig.
Robert Stock: "CRETCH"
A noted gamer, Stock has gone by "Cretch" as his gaming pseudonym for years.
Matt Strahm: "STRAHMY"
Christian Villanueva: "VILLA"
Trey Wingenter: "WINGENTER"
Kirby Yates: "KIRBS"
