Collin Morikawa on course for greatness after Open victory on his debut

• American finishes on 15 under, two shots clear of Jordan Spieth
• Overnight leader Louis Oosthuizen slipped to third

One can only wonder what Collin Morikawa's record might have looked like had he not appreciated the value of education. His arrival in the professional golfing ranks was delayed by four years as he completed a business administration degree at the University of California.

In making up for lost time Morikawa has now won two major championships in eight starts. He is in danger of depressing the rest of us, given this illustrious CV at the age of 24. Edmund Hillary was 33 when he planted his flag atop Everest.
