Spartak Saint Petersburg blew a big lead last week at ETHA in Cyprus but didn't make the same mistake twice as they stormed into the Eurocup.
After edging the first leg of the Qualifying Round tie, 60-59, despite leading by 14 in the second half in Nicosia, coach Jure Zdovc and Spartak returned to Russia and rolled to an 83-64 victory.
Point guard Patrick Beverley erupted for a game-high 26 points and also came up with five steals for Spartak, last year's Cup of Russia winners.
Spartak had only a 24-21 advantage early in the second quarter but went to half-time with a 49-36 lead.
Beverley, Valery Likhodey and Loukas Mavrokefalidis each had 10 points and Yotam Halperin nine with five assists at the break for the home side.
The Russians stayed in command for the remainder of the second leg and clinched a 20-point triumph on aggregate.
Halperin finished with seven of his team's 19 assists.
ETHA's Nigerian center Patrick Okafor led the team with 15 points.
