Sakkari through after major scare in St Petersburg
Maria Sakkari saved a match point before reaching the last 16 of the St Petersburg Ladies Trophy along with Elena Rybakina.
Sixth seed Maria Sakkari came from behind to earn a dramatic win over qualifier Vitalia Diatchenko as the St Petersburg Ladies Trophy got under way on Monday.
The Greek beat her opponent in straight sets when they met in Adelaide last month, but the world number 89 put up more of a fight this time.
Sakkari, who reached the Australian Open fourth round, ultimately prevailed 3-6 6-4 7-6 (7-3) in two hours and 38 minutes after surviving an almighty scare.
Diatchenko twice failed to serve out the match in the deciding set and squandered a match point at 5-2, later paying the price in a tie-break where she fell 4-0 down and could not recover.
Comeback complete for @mariasakkari.
