Schortsanitis began playing professional basketball with
Iraklis in the
2000–01 Greek League season. Starting in the
2002–03 Greek League season when he was 17, he averaged 11.5 points and 6.2 rebounds per league game. His performance record would be a failure in Cantù's 2003–04 season, in the
Italian League; he lacked maturity and experience. He would return to Greece to play in the 2004–05 season with the Greek club
Aris.
Olympiacos In the 2005–06 season, Schortsanitis was transferred to
Olympiacos. He became a vital member of the team that reached the
EuroLeague quarterfinals, and his performances impressed
Panagiotis Giannakis, who picked him for the
Greece men's national basketball team at the end of the season. During the following two years, Schortsanitis failed to achieve consistency, and his chronic weight issues reemerged, to the point that he spent almost the entire 2007–08 season dealing with them. He came back in shape for the 2008–09 season, and helped Olympiacos reach the
EuroLeague Final Four. In the 2009–10 season, he made another step towards consistency, displaying his most mature performances with Olympiacos, on the club's way to the
EuroLeague Final, which they lost to
Juan Carlos Navarro's and
Ricky Rubio's
Barcelona, 86–68.
Maccabi Tel Aviv On 5 August 2010, Schortsanitis signed a two-year deal with the then five-time
EuroLeague champions,
Maccabi Tel Aviv of the
Israeli Premier League. His presence alongside
Jeremy Pargo,
Chuck Eidson, and
Doron Perkins helped the team reach the
2011 EuroLeague Final, where they eventually lost to
Dimitris Diamantidis' Panathinaikos, by a score of 78–70. Schortsanitis averaged 12 points, 4.1 rebounds and 1 assist per game throughout the
EuroLeague 2010–11 season, earning an
All-EuroLeague First Team selection. In the 2011–12 season, Schortsanitis fought a chronic knee injury, which affected his performance during the season, and left him unable to participate with the national team that summer. Nevertheless, he helped Maccabi reach the
EuroLeague quarterfinals, where they were topped by Panathinaikos, losing the series, 3–2.
Panathinaikos On 4 July 2012, Schortsanitis signed a three-year contract with the Greek club
Panathinaikos, worth €1.5 million
euros
net income. He reportedly turned down significantly more lucrative offers from
Baskonia Vitoria and
Galatasaray, among others, to return to Greece and fulfill his desire to play for Panathinaikos. In July 2013, Panathinaikos announced that Schortsanitis would not continue play for the club.
Second stint with Maccabi On 10 July 2013, Schortsanitis returned to
Maccabi after one season in
Panathinaikos, and signed a three-year contract with the defending
Israeli Premier League champions. In his comeback season with Maccabi, the club won
the finals of
that season's EuroLeague, which was the first EuroLeague championship won in Schortsanitis' career. Over 29 games played in the EuroLeague that season, he averaged 9.6 points and 2.6 rebounds per game, in 14.2 minutes per game of playing time.
Crvena zvezda On 2 August 2015, Schortsanitis signed a one-year contract with the Serbian club
Crvena zvezda. On 28 October 2015, he parted ways with Zvezda. In 6 games played with the club in the
ABA League's
2015–16 season, he averaged 4.8 points and 2.5 rebounds per game.
PAOK On 2 November 2015, Schortsanitis signed with the Greek club
PAOK, for the rest of the season. With PAOK, he averaged 13.4 points, 4.4 rebounds, and 1.8 assists per game, in the
European-wide 2nd-tier level
EuroCup's
2015–16 season.
Apollon Patras In December 2016, Schortsanitis joined the Greek club
Apollon Patras. However, on 28 December, he suffered a serious injury, as he
ruptured his
Achilles tendon, during one of the team's practices. The injury caused him to then miss the entire remainder of the
Greek Basket League 2016–17 season, and he was thus not able to play in any games with Apollon.
Aries Trikala On 18 October 2017, Schortsanitis returned to action, and joined
Aries Trikala of the
Greek Basket League, for the
2017–18 season. On 6 January 2018, he made his debut in a 76–86 loss to
Rethymno Cretan Kings, recording 6 points and one rebound, off the bench.
Ionikos Nikaias On 24 July 2019, Schortsanitis signed with
Ionikos Nikaias for the
Greek Basket League 2019–20 season.
NBA draft rights Schortsanitis drew interest from the
NBA's
Los Angeles Clippers in the summer of 2006, after having been originally selected in the 2nd round (34th overall) of the
2003 NBA draft; however, because he was still under contract with
Olympiacos at the time, he did not make a move to the NBA. In 2010, his contract with Olympiacos expired, and he elected to participate in the
NBA Summer League with the Clippers, with an eye towards joining the team; this time, however, the Clippers were unimpressed, and he failed to secure a contract with the team. On 30 July 2012, the Los Angeles Clippers traded the draft rights of Schortsanitis to the
Atlanta Hawks in a
sign-and-trade deal for
Willie Green. On 15 July 2014, his draft rights were traded to the
Oklahoma City Thunder in exchange for
Thabo Sefolosha, the rights to
Georgios Printezis, and cash considerations.
Retirement On 10 December 2020, Schortsanitis announced his retirement from playing pro club basketball. Thus, making him one of the eleven players from the
2003 NBA draft Class to have never played in the
NBA. ==National team career==
