As it turns out, arguably the best nickname from Players Weekend was drawn up without actually thinking anyone would see it.
Kyle Seager, the Seattle Mariners' star third baseman, turned heads across the league when Players Weekend jerseys were released featuring "Corey's Brother" as his nickname - a nod to his sibling, Corey Seager, who plays for the Los Angeles Dodgers.
"It was a joke right out of the beginning," Kyle told MLB Network Radio. "I didn't think they were actually going to put it on the jersey and it's actually been pretty funny."
While the 29-year-old Kyle took the field with one of the best nicknames in the league, his brother Corey opted to keep it simple and wear just "Seager." Kyle - the older brother - explained why the Dodgers shortstop opted not to get in on the family fun.
"I asked him about it and he basically said he didn't know I was going to do anything," Kyle said. "I didn't tell him anything, I was hoping it just kind of came out day of. And then it came out a few weeks earlier, you know, he pretty much told me that I got lucky that he didn't know we were doing this."
It's not often that a player on the precipice of his sixth-consecutive 20-homer season is faced with a brother who may be even better, but such is the case with the Seager siblings.
"It's been incredible ... You knew really early with Corey that he was really, really talented," Kyle said.
"In 2011, I had just gotten called up and was working with my brothers in the offseason, trying to tell them about some of the stuff I'd learned and all this other stuff. And Corey just had a knack for picking things up. ... He's in high school and I'm like, 'Well this isn't good, my high-school brother is better than me and I just got called up to the big leagues.'"
In just his third season, the 23-year-old Corey is slashing .313/.395/.507 with 19 home runs - the same number of dingers as Kyle - and ranks fifth in the National League by WAR.
While Corey may rank higher by WAR, Players Weekend seems to have revealed which sibling has the better sense of humor.
