Pierre Herbert vs Gael Monfils prediction

1st round match at the ATP Halle and we have Herbert playing against Monfils. This match I think will have less than 9 games in the 1st set, I expect something of a 6:3 or 6:2 win for either player. Of course on grass court this type of results doesn't happen so much but not with these two players. Both players are not really used to playing so many games and it's easy for either to lose easily when things ain't going well
