AUGUSTA, Georgia (Reuters) - Jordan Spieth's sublime putting on some of the most treacherous greens in golf, which set up his Masters victory on Sunday, was underpinned by his imaginative touch, says putting maestro Ben Crenshaw.

While Crenshaw is acknowledged as one of the best putters of all time, he was mightily impressed by the manner in which his fellow Texan was able to adapt to the deceptive pace and tricky lines at Augusta National aged just 21.
