Caitlyn Jenner -- Check Out My Tips ... On the Course (PHOTOS)

Caitlyn Jenner proved she can keep up with the boys ... by playing from the most difficult tee box on the golf course.

Jenner hit up Sherwood Lake Club in Thousand Oaks, CA earlier this week, and drove her balls from the tee box farthest from the hole. Golfers call it the tips, and it's reserved for the most skilled players.

Caitlyn is a member of the exclusive Sherwood Country Club -- but while that course is under construction -- members have access to the 3-par course at the Lake Club.

As we previously reported -- Caitlyn will have to reestablish her golfing handicap with the USGA now that she's a woman. This oughta help.
