Defending champion Panathinaikos will start the Top 16 without one of its top stars, big man Mike Batiste, after he tore a calf muscle in a domestic game. Batiste, 33, was injured during a Greek Cup semifinal game on Wednesday. He is expected to miss at least 10 days, including the opening game of the Top 16, in which Panathinaikos hosts Partizan Belgrade next Wednesday in Athens. The injury is the third this season for the two-time Euroleague champ, who has already missed four Euroleague regular season games. Since returning to play and before this latest injury, however, Batiste was on his game, averaging 16 points and 5 rebounds. Worse still for Panathinaikos is that Batiste will join another veteran and two-time champ, power forward Kostas Tsartsaris, on the injured list. Tsartsaris will miss the entire Top 16, leading to an expectation that Panathinaikos will want to sign another big man to its frontcourt.
