British number one Jack Draper made comfortable progress to the last 16 at Queen's with a 6-3 6-1 victory over American Jenson Brooksby.
The two were meeting for the second time this year, with Draper beating the 24-year-old at Indian Wells in March.
On that occasion Draper had to recover from going 4-1 down in the first set but there was no such trouble this time as he broke Brooksby's serve in the seventh game before grabbing the double break to seal the set.
It was once again sweltering conditions in west London with the temperature at 26C when Draper and Brooksby entered the Andy Murray Arena, but the addition of a gentle breeze would have made things more palatable for the players.
But Draper, 23, still had no desire to hang around too long on court.
He broke Brooksby on his first service game and continued his momentum after a pause in play for a medical issue in the stands to get a second break and seal the win.
Draper, who wrote "Good to be home" on the television camera afterwards, will next face Australian Alexei Popyrin for a place in the quarter-finals.
In other action on Tuesday, Czech Jiri Lehecka saw off fifth seed Australian Alex de Minaur 6-4 6-2 to progress to the last 16.
