Home-court advantage was once again the order of the day in Euroleague as Laboral Kutxa and Lokomotiv Kuban beat Panathinaikos and Barcelona respectively.
CSKA Moscow and Fenerbahce had secured home wins over Crvena Zvezda and Real Madrid on Tuesday, with Wednesday's action following a similar script.
Lokomotiv grabbed a first Euroleague play-off win in their history courtesy of a thrilling 66-61 scoreline.
The visitors enjoyed a six-point lead at half-time, but Lokomotiv had cut that lead to three by the end of the third quarter.
Five lead changes followed in the final period, but the hosts put together a crucial 8-0 run to end the game and secure victory over the two-time winners.
Darius Adams led Laboral to victory with a 12-point burst in the third quarter as they saw off Panathinaikos 84-68, Ioannis Bourousis also chipping in with 15 points.
Panathinaikos' Miroslav Raduljica was the game's highest scorer with 21 points, but he only managed two in the second half as the Athens side laboured.
