Player profile
Šiškauskas was a physical small forward, who could also easily play, both on offense and defense, in either the point guard or shooting guard positions, on the wing, and also in the paint. His excellent leaping ability, and his quickness, made him a surprising shot blocker, and one of the best one-on-one players and swingmen in Europe. He was considered the best defensive player of the senior Lithuanian national basketball team. He led the 2003–04 season of the Lithuanian League, in free throw percentage (90.6%).
On May 15, 2009, Šiškauskas signed a contract extension with CSKA Moscow. He signed through 2011. Šiškauskas said of the contract: "I feel like the right man, in the right place in CSKA. I am happy with both the team, and the organization. That is why I don't see any reason to think about changes. I feel myself as a part of history of a great club, which is aiming for the highest goals. And that's what absolutely matches with my character."
