Holding Flag Stick
Question: - Can I hold the flag stick with one hand and putt with the other?
Answer: Yes.
The rules state that you can do this providing that the flag stick has been removed from the hole (Decision of the Rules of Golf 17-1/5)
If the ball were to strike the flag stick you would breach rule 17-3a and incur a 2 shot penalty for strokeplay or loss of hole matchplay.
You must ensure that the flagstick is not touching the ground whilst you are putting.
