Valentin Vacherot is running into some form ahead of his Shanghai Masters defence. The eighth seed has a tough match in the quarter-finals of the outdoor hard court Japan Open as he takes on qualifier Arthur Fils. An analysis of the statistics has led us to make a prediction of more than 20.5 games.

Vacherot has had two difficult matches so far in this ATP 500 tournament. The first round saw him beat Alexander Blockx in straight sets, but both went to 7-6. Then followed a three-set victory over Stefanos Tsitsipas after losing the opener. He's played more than 20.5 games in each of his last five best-of-three sets matches.

A side bet on a tie-break is advisable as he's played at least one in six of his last seven matches.

Arthur Fils is ninth in the world, nine places higher than Vacherot, but he had to qualify to get into the main draw in Tokyo. He did so, but both of his qualifying matches went to a deciding set with more than 20.5 games played. That was the case in his straight sets win over Frances Tiafoe in round two.

He's played more than 20.5 games in four of his last five matches played over three sets.
