Nigeria’s Micheal Osewa caused the biggest upset so far at the 39th ITF/CAT Africa Junior Championship in Pretoria, South Africa by beating tournament’s number one seed, Younes Adnane, of Morocco 1-6, 6-3, 6-2 to qualify for the quarterfinal of the boy’s 14&under.

The sixth-seeded Osewa started the tournament on a losing note as he fell 6-4, 6-4 to Eliakin Coulibaly of Ivory Coast but bounced back to contention with back-to-back wins over Salum Mutabazi of Burundi and Codie Van Schalkwyk of Namibia to set up a last-16 clash with Adnane.

The game at the University of Pretoria High Performance Centre, seemed to be heading the way of form book as the Moroccan took the first set in a convincing manner hitting series of winners for a 6-1 triumph. However, Osewa, a semi-finalist at the last edition in Tunisia, took the second set 6-3 forcing Adnane to lose his unblemished record as he had yet to drop a set before.

Osewa completed a memorable win in a 6-2 final set to set up a quarterfinal meeting with Jason Espitalien of Mauritius.

Friday was adjudged as one of the standout performers of the tournament winning all his preliminary matches – the most memorable of which was against Morocco’s Assil Boussairy – in straight sets but had his run halted by the homeboy.

Christopher Itodo also exited the boy’s 16&under on Monday as he lost 6-0, 6-0 to Philip Henning of South Africa to join Adetayo Adetunji, Angel McLeod and Marylove Edward who all failed to progress from the preliminaries.
