ATP Finals: Jannik Sinner maintains 100% record with win over Ben Shelton

Already eliminated Shelton took an aggressive approach in the first set, utilising his athleticism to rush the net, particularly on Sinner’s second serve where he won five of eight points.

But, as happened in Sinner’s victory over Zverev on Wednesday where he saved all seven break points he faced, the second seed was clinical in the key moments.

He converted two of his three break-point opportunities, striking in the first and ninth games, produced a run of big first serves, including two aces, to save a break point on his own serve, and struck 13 winners to Shelton’s eight.

Both players were efficient on serve in the second set, with Sinner giving up just seven points across six service matches and Shelton holding three of his own to love while also saving the only break point of the set in the 10th game.

However, Sinner once again demonstrated his composure in the tie-break, leading 4-1 and 6-3, and offering up a small smile before securing the win with his second match point.
