Dexia Namur will take their EuroLeague Women eighth-final play-off serious back to Istanbul next Wednesday after defeating Fenerbahce 66-59 on Friday night.
Fener stormed to an 80-66 win in the first game between the two sides, but game two proved to be a different prospect altogether for the Turkish outfit.
Trailing 48-54 at the start of the fourth quarter, Dexia turned to Deyaert and she delivered in style, scoring seven straight points to bring her side to within three points, 53-56.
Cathrine Kraayeveld then split a pair from the line and after Katryna Gaither blocked Cappie Pondexter's lay-up attempt, Polish veteran Krystyna Szymanska-Lara hit a jump shot for Dexia to tie the score at 56-56.
Two more free throws by Szymanska-Lara gave Dexia their first lead since the second quarter and Deyaert nailed another pair from the line to cap a 14-2 run and a 60-56 lead.
Gaither added insult to injury following another Pondexter miss on the next play, hitting a lay-up from an offensive rebound to extend the lead to 62-56.
It was then a case of hanging on for the home side, and despite a couple of shaky moments down the stretch, Annemarie Parau's two free throws sealed the win.
Fenerbahce shot just 2/15 in the fourth quarter and 0/4 from the free throw line.
Gaither led the way for Dexia with 21 points and 10 rebounds, while Deyaert had nine of her 10 points in the fourth quarter.
