Sinner turns on the heat

Jannik Sinner (above) hit the accelerator at the end of each set as he cruised past Taylor Fritz 6-4, 6-4 on Tuesday night to close in on a semifinal spot at the ATP Finals in Turin.

In September, Sinner had to overcome raucous home support to win his last meeting with the American as he claimed victory in the final of the US Open, also in straight sets.

This time, the Turin crowd was mostly behind the Italian. "The crowd is helping me a lot," said Sinner on the court.

The hard-hitting Fritz, ranked No. 5, put pressure on Sinner's serve early in the first set. The American had the first break point of the match in the 14-minute seventh game but could not take his chance.
