Barons improved to 4-1 and took over sole possession of first place in Group D of the EuroCup with a 71-65 win over nearest challengers Khimik.
Demetrius Alexander scored 17 points and had 10 rebounds for Barons, who take on Cholet Basket next week while Khimik (3-2) will have to battle to stay alive in the competition when they take on third place Lokomotiv Rostov (2-3).
Riga outfit Barons, who were playing away from home in Yuzhny, looked to have established control from the off against the team that beat them by six points in their previous encounter but Khimik came back with a 12-0 run to start the fourth quarter that gave them a 60-51 lead with just under eight minutes remaining.
Aleksandar Djuric scored the last seven points in that surge with a jump shot, a tap-in and a three-pointer.
But Khimik weren't able to press home the advantage.
Instead, Barons, who had twice opened up leads of 12 in the third quarter, mounted a fightback.
Alexander hit a pair of free throws that came at the front of a 17-0 run which lasted seven minutes as Barons took control at 68-60.
Khimik managed to close the gap to three points but Barons won the day.
Giedrus Gustas finished with 14 points for Barons, who shot 10 of 20 from three-point range.
Karlis Muiznieks, the head coach of Barons:
"In the forth quarter we began to loose the nine point lead I had to change the game. We played zone defense and it worked. I am very thankful to all my players for the game. This winning game is really very important for us."
Dainius Adomaitis, Barons:
"We were better on defense today and allowed BC “Khimik” to score only 65 points. It’s really a very great result. Of course all of us understood that the game has only 40 minutes but not 30 or 35. That’s why we fighted to the end."
Dmitriy Bazelevskiy, Khimik head coach:
"From the very beginning of the game we played very bad. We’ve made many mistakes on offense, we had very low percent tonight. Probably the players lost the tact of the game (burned out), although we have good thoughts before the game, and all players understood the importance of this victory."
Aleksander Djuric, Khimik:
"It’s really a pity that we lost today. We needed the victory. Now we will have to prepare extra hard for the game with Lokomotiv- Rostov , to decide the tasks of exit from the group."
