Odell Beckham Jr. Hits the Beach in Cancun with Girlfriend Polyxeni Ferfeli

Odell Beckham Jr. is going to training camp soon, and it looks like he's getting a head start by treading water with some very hot weight bogging him down.

The New York Giants wide receiver hit the beach in Cancun, Mexico Saturday with girlfriend Polyxeni Ferfeli. They've been dating since April and possibly longer ... they've kind of kept it on the down low.

Odell's entering his 4th season with the team ... so it stands to reason he gets a big hug for good luck!
