The Russian player forfeited the match, while El Aouni was in the lead (6-2, 2-0).
El Aouni, ranked 788th in the WTA rankings, bested Kazakhstan's Sandugash Kenzhibayeva in the semi-finals in two sets (6-3, 6-0), while Yushchenko qualified at the expense of the Slovenian Anika Jaskova (6-4, 6-4).
This is the 18-year-old Moroccan's second consecutive title in the ITF (International Tennis Federation) Antalya Series, after her victory last week over the same Yushchenko in the final of the W15/17A Antalya tournament by two sets to 1 (2-6, 7-6, 6.3).
