Two unseeded players will battle it out for a place in the outdoor hard court Japan Open. This match is being played in Tokyo and unseeded Jiri Lehecka takes on qualifier Adolfo Daniel Vallejo. The latter is in good form and Lehecka has already dropped two sets, so our prediction is Vallejo wins a set.

The winner will face either eighth seed Valentin Vacherot or qualifier Arthur Fils in the semi-finals of this ATP 500 tournament.

Jiri Lehecka has won 17 of his 27 outdoor hard court matches played this year. This is his fourth quarter-final of the year.

It's not been an easy route to the last eight for Lehecka. He needed to go to three sets to defeat Zizou Bergs in round one.

Then in the second round, he had to come from behind to get past Ugo Humbert.

Lehecka has lost a set in seven of his last eight matches played in singles tournaments.

Adolfo Daniel Vallejo is the world number 56, 33 places below his opponent.

He has had to win four matches to reach this quarter-final and only dropped one set. Wins have come against Taro Daniel, Jaime Faria, fourth seed Rafael Jodar and then Matteo Berrettini. He has won at least one set in each of his last eight matches.
