World number one Jannik Sinner remains on course for a record fifth consecutive Masters 1,000 title after reaching the Madrid Open final with a straight-set win over Arthur Fils.

The Italian won his 22nd successive match to reach Sunday’s final, where he will face either second seed Alexander Zverev or unseeded Belgian Alexander Blockx.

Sinner, 24, has won the opening three ATP 1,000 events of the season – in Indian Wells, Miami and Monte Carlo – and also triumphed in Paris late last year.

The four-time Grand Slam winner broke twice to take the first set 6-2 against 21st seed Fils, who won the clay-court Barcelona Open two weeks ago.

Fils, 21, was 3-2 up in the second set having saved two break points, but Sinner finally broke to move 5-4 ahead and served out the match to progress 6-2 6-4.

Zverev and Blockx play their semi-final later on Friday.
