• Fritz triumphs 6-4, 3-6, 7-6 (4) in battle of big servers
• American will face Casper Ruud or Jannik Sinner in final

The greatest season of Taylor Fritz’s career extended for another day as he toppled Alexander Zverev in a tense, quality tussle to reach the final stage of the ATP Finals for the first time. In a tough battle between two of the best servers in the world, Fritz held on to narrowly defeat Zverev 6-4, 3-6, 7-6 (4).

With another tremendous victory, Fritz now sits at No 4 in the ATP live world rankings, and only a title for Casper Ruud would stop him from rising to a new career high on Monday.
