Golf only really throws up genuine unparalleled achievements every decade or so.
Jack Nicklaus winning the Masters at the age of 46 in 1986, and Tiger Woods taking all four majors at once, 14 years later, spring to mind. And we can now add to that list the sensation that is Yani Tseng, surely the greatest female player of all time.
The Taiwanese won the Women's British Open last Sunday, a feat made all the more remarkable that she is only 22.
It was the fifth major title for the "Taiwanese Tiger" and a fourth victory from the last eight majors.
She came from two behind the overnight leader Caroline Masson at Carnoustie to produce a final round of 69 to win by four clear strokes of eventual runner-up Brittany Lang. Tseng also won the tournament last year, and this successive victory puts her head and shoulders above the rest.
Even if Carnoustie was not as unforgiving as it has been for the last two men's British Opens, in 1999 and 2007, because the pin positions were almost as fair as the weather, Tseng brilliantly tamed this fierce links course with a final score of 16-under par.
At a little over five foot tall, Tseng relies on her short game more than others, but even when her putter was not quite so hot, as was the case in Scotland, she was still dominant.
"I hope to keep winning. Next year there are another four majors and I will work hard to get them all," Tseng said. The scary thing is that she might just do that.
