Listed at 1.98 m (6 ft 6 in) tall,[1] he could play at both the shooting guard and small forward positions.

He was a member of the senior Lithuanian national team that won the gold medal at the EuroBasket 2003.

He played in 32 EuroLeague games over two seasons with Benetton, and averaged 12.3 points, on 60 percent shooting.

[3] Only one week after the 2012 EuroLeague Finals game, on May 21, 2012, Šiškauskas announced his retirement from playing professional basketball.

With Lithuania's junior national team, he played at the 1998 FIBA Europe Under-20 Championship.

After the 2008 Summer Olympics, he officially announced that he was stepping down from the Lithuanian national team as a player.

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.

I feel myself as a part of history of a great club, which is aiming for the highest goals.
