Near the top of the ATP small things can make huge differences.
Jannik Sinner goes for more on his serve when he is behind, none of this "make sure you get your first in" namby-pamby stuff. And it works.
Sunday, Sinner joined august company with Fed, Nadal, and Pete Sampras as the only 4 players to win a slam final without facing a single break point.
How? One factor is that Sinner serves faster and wins a higher percentage of his points when down.
Jeff Sackman has the numbers on Tennis Abstract's "Heavy Topspin". At 40-love, Jannik slows down to a crawl, serving at an average speed of only 113 MPH. But at 15-30, he ramps it up to 121 MPH. And Sinner does it without paying a price:
> With more at stake, the Italian hit harder. There’s no apparent trade-off, either. He made more first serves than average at 15-30 and deuce, even with the faster strikes.

Here are Sinner’s first-serve speeds at the most common point scores he faced:
Score MPH
15-30 121.0
40-40 120.3
40-15 120.0
0-15 119.7
30-30 119.4
40-30 118.0
30-15 117.7
30-0 117.0
15-0 116.6
0-0 116.6
15-15 115.8
40-0 113.0
(Yes, I know it’d be nice to have 30-40, 40-AD, 15-40, and so on. But this is Sinner we’re talking about. He didn’t face many of those.)
