Nina Agdal Goes Long and Straight

Nina Agdal obviously looks great when she's modeling on the beach for Sports Illustrated ... but that's nothing compared to how she looks off the tee.

Agdal just posted video to her Instagram showcasing her driving skills. She SMASHES the ball with a follow-through worthy of LPGA contention.

The supermodel is known to be an avid golfer, clearly the practice has paid off.
