Former World No.1 Daniil Medvedev crashed out of the Dubai Championships on Thursday, squandering four match points before losing a bad-tempered quarter-final to Tallon Griekspoor of The Netherlands. The 47th-ranked Dutchman came through 2-6, 7-6 (9/7), 7-5 as the World No.6 imploded. Medvedev, the 2023 champion in Dubai, was handed a code violation for unsportsmanlike behaviour after seeing match points slip away in the second set. It is not known what Medvedev said to invoke the violation.
