Pro Golfer Stewart Cink -- I NEVER Play With Myself ... In Tiger Woods' Video Game

Playing yourself in a video game is one of the first big signs that you've "made it" as a pro athlete -- but pro golfer Stewart Cink actually expects us to believe he's never ONCE indulged in a little virtual self-love.

The '09 Open champ was on his way to catch a flight at LAX ... and we asked if he's ever given into temptation ... and taken his character for a swing in Tiger Woods PGA Tour.

Cink SWEARS he hasn't tried it ... but admits his kids love to play as their dad.
