Head-to-Head
Rei Sakamoto and Billy Harris have not previously met on tour.

Rei Sakamoto Player Overview
Rei Sakamoto arrives at this match in good form, having won eight of his last 10 matches. In two matches at the tournament he has beaten Kasidith Samrej and Zhizhen Zhang. He holds serve comfortably - winning 80% of his service games, with a first-serve percentage of 68%.
Also worth noting is his high set-winning rate (73%) and a tendency to win without dropping a set - six of his last 10 matches ended 2-0. However, his winning margins in games are not always large: even in victories the difference is often narrow, which affects the case for backing him on a negative games handicap against comparable opponents.

Billy Harris Player Overview
Billy Harris is going through an inconsistent spell - just four wins from his last ten matches. That said, he has covered the +3.5 games handicap in 13 consecutive matches. In the two previous rounds of the tournament he beat Changjun Kim and Alexander Vukic.
Despite a modest first-serve percentage of 61% and a service games won rate of 70%, Harris consistently wins more than 10 games per match even in defeat, and his matches tend to go long - averaging 26.5 games per match. That makes a large margin in the final score relatively uncommon.
