Australian Jordan Thompson has blitzed his way into the quarter-finals of the ATP Tour's Hall of Fame Open with a straight-sets win over Yuichi Sugita.
The tournament's No.7 seed hardly raised a sweat in a 6-0 6-2 victory over the Japanese player.
He will now meet American Maxime Cressy, who upset No.2 seed and fellow countryman Sam Querrey 6-4 2-6 6-2.
Alexander Bublik is the top seed in the tournament and he advanced to the last eight with a 7-6 (7-5) 4-6 6-1 victory over wildcard Ivo Karlovic.
"Ivo is a great player and there is not much to say about this match other than it was server versus server," Bublik told the ATP Tour website.
"In the first set, I got a bit lucky and he gave me two double faults; in the second set I gave him (four) and he gave up five in the third.
"I'm happy to get through and I'm happy to be in the quarter-finals."
Among those to progress are two-time grand slam finallist Kevin Anderson, who beat Sebastian Ofner 7-5 6-3, Jack Sock and Jenson Brooksby.
Sock, who knocked out Australian qualifier Alex Bolt in the first round, beat Yoshihito Nishioka 6-2 6-3 while Brooksby had to work hard for his 6-3 4-6 7-5 win over Denis Kudla.
