Experience, meet youth. The latest flashy wunderkind to blaze a trail in the men's game, Nick Kyrgios, received some unsolicited if solid advice this week from one Nick Bollettieri, a titan of tennis execution.

First, Bollettieri tweeted his admiration of the 20-year-old Aussie phenom, adding that better days ahead for him if he plays his shots right. Bollettieri also posted that Thanasi Kokkinakis has quite the upside as well, then noted, "There's work for them to do to reach the top."


Kyrgios' tweeted reply beckoned Bollettieri to teach him his ways, as he has so many greats to date, including Andre Agassi, Monica Seles, and Jim Courier. Now 83, that inimitable pillar of tennis instruction did just that, delivering a lengthy letter to Kyrgios, observing that the Aussie needs to improve his backhand (as Maria Sharapova and Agassi did over time) and calling him a "character" akin to those he has shepherded in past decades. (In a word, Andre.)

Spin it yourself: Does Kyrgios have a major title, or more than one, in his future?
