Hard to say, but it's worth noting that center fielder Franklin Gutierrez arrived at Mariners camp sporting a nearly identical cut.
"I don't know if he's copying me," Hernandez said with a smile, "but I had it first."
Outfielder Mike Wilson also has a Mohawk, which he said he's had since he went to Venezuela for winter ball over the offseason.
As far as Hernandez is concerned, it doesn't matter who got the first cut. He's got the copyright on what some are dubbing the "Fe-Hawk."
His arrival at the new 'do back in December was pretty simple.
"My barber was cutting my hair and I said, 'Dude, let's do something different,'" Hernandez said. "I've had short hair and long hair and medium hair, and I wanted something different. He said, 'We can do a Mohawk,' and I said, 'Let's do it.'
"When he was finished, I looked in a mirror and I said, 'Ohh, I like it.' So I stuck with it."
The cutting-edge barber lives about a half hour out of Valencia, Venezuela.
"We call him Crazy Barber," Hernandez said.
The 24-year-old isn't about to say the Fe-Hawk is catching on. In fact, he's not even sure how long it'll last on his own head.
"I don't know, man. I tell you, I'm going to let it be for a little bit," he said. "But when the season starts, if something happens -- if I lose a couple games -- it's gone."
