Day 3 Recap
Medvedev and Zverev put on a spectacular serving display as part of a match that lived up to the hype. It wasn't decided until deep in a third-set tiebreaker.
The pair combined for 32 aces (18 for Zverev and 14 for Medvedev) and just three double faults. They also saved seven of the match's eight break-point opportunities, with the only exception coming early in the first set when the second-seeded Russian broke in the German's first service game.
Zverev won the second-set tiebreaker rather convincingly after dropping the first set, and he raced out to a 4-2 lead in the deciding breaker before Medvedev mounted a rally by winning four straight points to take a 6-4 advantage.
The 2021 US Open champion failed to convert his first two match points before winning the next two points to pick up the crucial victory.

Sinner didn't have much trouble with Hurkacz, although both players had their chances in this one.

A win for Sinner. A win for Italy. 🇮🇹 <a href="https://twitter.com/janniksin?ref_src=twsrc%5Etfw">@janniksin</a> - that was special. <a href="https://twitter.com/hashtag/NittoATPFinals?src=hash&ref_src=twsrc%5Etfw">#NittoATPFinals</a> <a href="https://t.co/2oOjnPq9zQ">pic.twitter.com/2oOjnPq9zQ</a>
The eventual victor converted four of six break-point opportunities, while Hurkacz went 0-of-5.
First-serve opportunities proved to be a big difference as well with Sinner winning 29 of 39 and Hurkacz earning 18 of 31.
The turning point in the first set occurred with Sinner serving up 2-1. Hurkacz earned three break-point chances but could not convert. Sinner held serve before breaking Hurkacz for a 4-1 lead en route to a 6-2 finish.
Hurkacz had another chance to get back into this match in the second set when he earned a break-point chance up 1-0, but Sinner won three straight points to take the game. Sinner then broke Hurkacz and cruised from there for another 6-2 victory en route to the straight-set win.
The 20-year-old made some history with his excellent performance:
Looking ahead, the Green Group returns to the spotlight Wednesday as No. 1 Novak Djokovic (1-0) takes on No. 5 Andrey Rublev (1-0) and No. 4 Stefanos Tsitsipas (0-1) battles No. 8 Casper Ruud (0-1).
