Sylvester Emmanuel, the only Nigerian player who was contesting for a spot in the quarterfinals, retired due to a wrist injury against Zimbabwe’s Benjamin Lock while trailing 0-6, 0-3 in their second round encounter on Thursday.
Lock, who’s ranked 548th in the world, had sped to a first set win and was up 3-0 in the second set, before Emmanuel called it quits as a result of the injury.
For a place in the semifinals, the Zimbabwean will take on third seed, Arjun Kadhe of India, who dismissed Burundian, Guy Orly Iradukunda, 6-2, 6-2 in 59 minutes.
On Centre Court, second seed, Sadio Doumbia recovered from an opening set loss to beat his countryman, Maxime Mora, 5-7, 6-3, 6-2.
Doumbia, who had dropped only a game in his first round match win, squandered a 5-2 lead in the first set, as Mora fought back to win five games on the bounce and take the set. Doumbia would again open a 5-2 lead in the second set, but this time left no room for errors, as he held firm to take the set and level the match. The 28-year-old, who’s now the highest-ranked player left in the draw, would put his foot down to take the final set emphatically and close out the match in 2 hours and 22 minutes.
Up next for Doumbia is 18-year-old Swedish qualifier, Simon Yitbarek. Yitbarek produced a superb performance to beat his coeval, Gilbert Soares Junior of Brazil 6-4, 6-1 and advance to the quarterfinals.
Against the Brazilian, Yitbarek found the crucial break early in the first set for a 2-1 lead, and stayed composed the entire set to take it. The Swede’s brilliance shone brighter in the second set as he powered through to take the match in 76 minutes.
