This will be their first meeting.
Tiafoe has had a better season than Krajicek but on indoor courts they are more even.
Krajicek was underdog in his last match but beat Brian Baker in a third set tie break. His first serve was working well and he hit 15 aces but his second serve looked vulnerable.
I see some value on Krajicek at the start. Tiafoe made a slow start against Klein in the last round. He lost the opening set but after coming through a very tight second set he ran away with the third.
I think we could see a bigger price on Tiafoe again tonight. Back Tiafoe if he gets broken. He starts around 1.40.
