Nishikori/Hurkacz under 22 at -143 for 7 units. Hurkacz does have a strong serve, but Nishikori has a solid return game. Hubert Hurkacz is only a few months removed from his first ATP main draw win. He struggles against top competition and that was shown in his recent 6-4, 6-2 loss to Tsitsipas. Nishikori has made the quarterfinals in every tournament he has entered this year. Kei will be better at converting/defending break points. That will be the difference in this over/under.
