The EuroLeague champions have one foot in the Final Four as their playoff run continues whereas Olympiacos redeemed themselves in game two after being rocked in their opener against Zalgiris.
Fenerbahçe went 2-0 in their playoff series against Baskonia after they recorded a 95-89 win in Istanbul.
It was the 11th consecutive playoff win for Fener, which has not lost in this phase under head coach Zeljko Obradovic since he took over in 2013.
Brad Wanamaker led the way with 19 points.
After a disappointing loss in overtime in game one, Olympiacos levelled the series against Zalgiris with a 79-68 win.
The key to the victory was a 17-2 spurt from Olympiacos to bridge the first and second quarters, and although Zalgiris fought back to tie twice, the visitors could never move ahead and a strong start to the final quarter took the Reds to the finish line.
Jamel McLean – taking an enhanced role due to Nikola Milutinov’s injury – led the scoring with 21 points.
