After a senior career that's spanned 18 years, we're used to seeing Roger Federer do amazing things on the tennis court.
But he's still finding ways to hit new heights.
Up a break against Czech Tomas Berdych in the quarter final of the Miami Masters, Federer hit a backhand drop-shot that looked like it was going well long.
With Berdych not moving and the ball going at least 15 feet in the air, the ball dropped over the net and spun back toward the net to the delight of the crowd.
The point sent him up a second break which was backed up with a love service game, bagging the first set for Federer 6-2.
The Swiss Superman went on to win the match after claiming a third set tiebreaker.
Fourth-seed Federer had to call upon all his resources of skill, poise and experience to edge Czech No.10 6-2 3-6 7-6 (8-6).
Berdych served for the match at 6-4 in the tiebreak, but could not convert, with Federer reeling off four points in a row, winning when Berdych double-faulted on the first match point for the Swiss ace.
Earlier, Federer looked set for another emphatic victory after taking the first set.
The Australian Open champion, who also won at Indian Wells two weeks ago, has lost only once this year, to Russian Evgeny Donskoy in Dubai.
The last of the quarter-finals at the ATP World Tour Masters 1000 event pits Australian No.12 seed Nick Kyrgios against German No.16 seed Alexander Zverev, with the winner earning a semi-final showdown with Federer.
In the bottom half of the draw, unseeded Italian Fabio Fognini will face Spain's fifth-seed Rafael Nadal for a spot in the final.
