Gabriel Diallo vs Billy Harris prediction
Gabriel Diallo continues his grass court season at Queen’s after the best week of his career as he picked up his maiden ATP Tour title at the Libema Open in the Netherlands. He dropped just one set during the whole tournament and beat the likes of Ugo Humbert and Karen Khachanov. The 23-year-old defeated Zizou Bergs in the final and will be full of confidence heading into this event.
Great Britain’s Billy Harris will be his opponent in round one. Harris enters the main draw as a wildcard. He has competed in two grass court event on the Challenger Tour over the past couple of weeks but hasn’t been able to produce a deep run in either. He lost in the first-round of the Birmingham Classic and could only make the round-of-16 of Ilkley as the third seed.
Diallo is currently on a five-match winning run, and we predict that he’ll extend his winning streak against the world number 113 with a dominant win.
