The first night of Top 16, Week 5 action delivered all the drama with a buzzer-beating thriller, a fantastic atmosphere in the derby of Istanbul and a brilliant performance by a serious title contender. The results from those first three games ushered in the first team to the 2012 Turkish Airlines Euroleague Playoffs, eliminated two other teams and set up a win-or-go-home game next week. Thursday’s five games could decide the fate of 10 more teams with six playoff tickets potentially on the line. The week began in the Russian capital, where CSKA Moscow dominated Olympiacos 96-64 to bounce back from its first loss of the season by advancing to the playoffs and clinching first place in Group E. Andrey Vorontsevich scored 15 to lead six CSKA scorers in double figures as the team won its 10th straight Euroleague home game. Later in the same group, GS Medical Park KO’d rival Anadolu Efes 64-56. Luksa Andric scored 15 to lead the Euroleague debutantes, who travel to Olympiacos next week to battle for the remaining playoff ticket from the group. Galatasaray will advance if it wins – or even if it loses by 1 point. Olympiacos heads to the playoffs if it wins by 2 or more. The loss ended Efes’s hopes of reaching the Turkish Airlines Euroleague Final Four, which will be played on its home floor this season. Wednesday’s other game was in Group E, where Gescrap BB edged Montepaschi Siena 60-59 on a Raul Lopez buzzer-beater. The loss denied Montepaschi a chance to reach the playoffs already, though the Spanish champs and Bilbao could both still advance this week if Unicaja beats Real Madrid Thursday. Marko Banic tallied 16 points and 8 rebounds and Lopez scored 15 for the men in black. Thursday features another game in Istanbul as Fenerbahce Ulker (1-3) meets Unics Kazan (3-1) in a crucial showdown in Group G. Unics advances with a win; FB Ulker needs to win by more than 5 to guarantee it enters the Top 16 final with hope of a playoffs spot. Group H features a showdown between the freshly crowned Israeli Cup and Lithuanian Cup champions with Maccabi Electra (2-2) facing Zalgiris Kaunas (0-4) at 20:05. Zalgiris is out if it loses; Maccabi could potentially advance later in the night if it wins and Barcelona beats Cantu. Another team coming off a cup triumph plays at home in Group F as Real Madrid (2-2) hosts Unicaja (0-4) at 20:45. A loss for Madrid ends Los Blacos’ playoffs hopes and sends both Siena and Gescrap through. The Turkish Airlines Euroleague Game of the Week come from Group H, where Bennet Cantu (2-2) takes on FC Barcelona Regal (4-0) at 20:45. Barca can clinch a playoffs berth and first place in the group with a victory; Cantu could know by halftime whether it’s facing elimination. The last game of Top 16, Week 5 takes place in the Greek capital where Panathinaikos (3-1) plays EA7 Emporio Armani Milan (1-3) at 21:00. The Greens can seal their playoff fate with a win; Armani will knows before tipoff where it stands and in the event of a Unics win earlier in the evening, it will need to win by more than 21 to stay alive.
