World No 1 Luke Humphries stormed into the quarter-finals of the UK Open, where a final versus Luke Littler remains a possibility. Humphries had to rally from 7-5 down to beat women's world No 1 Beau Greaves in the fourth round on Friday night but was ruthless on Saturday, sweeping good friend Ryan Searle 10-0 before trouncing Ryan Joyce 10-2 in a pair of statement performances. Meanwhile, Stefanos Tsitsipas secured a maiden ATP 500 title with a straight-set victory over Felix Auger-Aliassime in the final of the Dubai Tennis Championships. The 26-year-old Greek produced a strong performance to beat his in-form Canadian opponent 6-3 6-3. This win marks Tsitsipas' 12th tour-level title and the biggest outdoor hard-court trophy of his career.
