"Brian Harman Takes Commanding Lead at British Open, R&A Makes Changes to Pot Bunkers"

Brian Harman holds a commanding five-shot lead after a stellar performance on Friday at the British Open, bringing him to 10-under for the tournament. Tommy Fleetwood is in second place at 5-under, followed by Sepp Straka in third at 4-under. Jordan Spieth and Rory McIlroy are within striking distance at 2-under and 1-under, respectively. Harman's lead is not guaranteed, as there are still two days of golf to be played, but it will take a significant effort from someone to close the gap before the final round on Sunday.
