10:07 AM PT -- A rep for the bowling alley tells TMZ Sports ... Russell was the big winner, bowling 148 ... and Justin placed 3rd.
The rep says Bieber only drank water ... alcohol was NOT served.
As for food, we're told "Justin only likes potato skins, and had the chef prepare 3 plates for the group."
Jesus saves ... but Bieber bowls ... which is why Russell Wilson made time for BOTH superstars in Seattle this weekend.
The Seahawks quarterback allowed Justin Bieber to join his entourage to pray with Pastor Judah Smith at The City Church on Sunday ... and it seems everyone had a great time.
Bieber even tweeted about it ... saying, "Blessed to hear one of the best @judahsmith speak today about our Lord in church today. #JesusIs."
After services, all three guys hit up Lucky Strike Lanes and got their bowl on. Unclear, who came away with the victory.
It's been a crazy jock-filled weekend for Biebs, who was in Vegas the night before ... hanging out with Floyd Mayweather at his fight.
