There'll definitely be a Spanish player in the final of the outdoor hard court Japan Open. Top seed Carlos Alcaraz faces qualifier Jaume Munar in the last four of this ATP 500 tournament. Alcaraz should win, but looking at his results this week, our prediction is more than 8.5 games in set one.

In the final, the winner will take on either eighth seed Valentin Vacherot or unseeded Jiri Lehecka.

Carlos Alcaraz is hoping to win his third tournament of a year that has been hampered by injuries. His last title triumph came in Doha eight months ago.

He has had three matches this week and only lost one set. That was the first round against Alex Michelsen.

Each of the three opening sets he's played this week has ended 7-6. 

More than 8.5 games have been played in the first set of each of his last 11 matches.

Alcaraz leads Munar 3-1 in previous meetings, three of those four matches had more than 8.5 games in set one.

Jaume Munar is a qualifier and has had to play five matches to reach the last four in Tokyo with one seed (Taylor Fritz) beaten.

Three of his five matches have seen more than 8.5 games played in the opening set.
