Pospisil V. vs Isner J. prediction

They already met 6 times previously and by now the score for H2H was 3-3 for them. From those 6 previous meeting they got 4 meeting which ended in 3 sets game with tie a break in any set; I believe those results already explained how tight their meeting are, and for today I fancy a similar result for them. This clash very likely ends in tie a break in any set or even all set and won't be end in straight set. I also count this clash are equal for them and predict that there will be over 25.5 games.
