British number one Cameron Norrie came from behind to reach the Queen's quarter-finals for a second time with victory over Australian Jordan Thompson.
Fifth seed Norrie, a Wimbledon semi-finalist last year, recovered from an error-prone display in the first set to win 4-6 6-3 6-2.
Norrie will face Frances Tiafoe or Sebastian Korda in the next round.
Later on Wednesday, Britain's Ryan Peniston faces second seed Holger Rune.
Norrie is playing in his first grass-court tournament of the season as he gears up for Wimbledon, which starts on 3 July. Hopes of getting even more match time on the surface were dashed on Wednesday when his scheduled doubles partner Andy Murray withdrew from the competition, citing fatigue.
