|Jean-Marc Mwema paced the Giants with a 13-point, 10-rebound double-double|
PO Antwerp Giants used an impressive second half to keep their qualification hopes alive and hand Tartu University Rock their first EuroChallenge Group I defeat, 64-59.
Antwerp's task was made all the more difficult with Yannick Driesen and Maxime De Zeeuw ruled out before tip-off through injury, and they trailed 33-30 at half-time as their visitors from Estonia looked for a ninth successive EuroChallenge victory.
Barry Stewart drew the home side level with a three-pointer early in the second half, and Marko Spica helped to spur the Belgian team on with timely buckets before Jean-Marc Mwema's three-pointer extended the lead to eight.
The visitors pushed in the final period, but they were held to 35.4% shooting in the match as PO Antwerp held on to boost their morale ahead of their decisive encounter with Krasnye Krylia Samara in Russia on 25 February.
Mwema recorded a double-double of 13 points and 10 rebounds as he helped the home team to dominate the glass, while Frank Turner led the Giants with 15 points.
Tartu Rock were led by 16 points and eight rebounds from Janar Talts.
Tartu Rock Head Coach Gert Kullamäe
"Congratulations to Antwerp on playing a very good defensive game. We go to the next round and maybe my players were somewhat relaxed today."
Tartu Rock Player Janar Talts
"It was a very difficult game. Antwerp was very good at home; they were tougher. We did not execute our three-point shots. Antwerp deserved to win."
PO Antwerp Head Coach Paul Vervaeck
"Today we had to play with a lot of energy. Without Maxime De Zeeuw we did what we had to do. Next week it will be a decisive game in Samara; the team that wins will go to the next round."
PO Antwerp Player Jean-Marc Mwema
"We had to play tough today. And most importantly, we could keep this very good team under 60 points."
