Brazil and Spain (1999–2010) Splitter began his professional career in 1999. In 2000, he began to play in Spain's top-level league, the
Liga ACB. In 2004, Splitter became a naturalised citizen of Spain. Splitter was named the
MVP of the
Spanish Supercup tournament in both 2006 and 2007. He was also named to the
All-EuroLeague First Team for the
EuroLeague's
2007–08 season, after helping
Saski Baskonia make it to the
2008 EuroLeague Final Four. The following year, Splitter reached the
EuroLeague 2008–09 season's playoffs, but failed to make another
EuroLeague Final Four participation. Nevertheless, his performances earned him a spot on the 2008–09 All-EuroLeague Second Team. Splitter was named the
Spanish League MVP in 2010. Splitter was expected to declare for the
2006 NBA draft, but because the expensive buyout of his contract discouraged
NBA teams with high draft picks from drafting him, he remained in the
Spanish ACB League for that season. Splitter was automatically eligible for the
2007 NBA draft, as he was at least 22 years of age at the time of the draft. He was selected by the
San Antonio Spurs, in the first round of the draft, with the 28th overall draft pick. On May 28, 2008,
ESPN Brasil reported that Splitter had re-signed with
Saski Baskonia, on a two-year contract that would keep him in the Spanish ACB League through the
2009–10 NBA season. The contract allowed the Brazilian to make eight times more than the NBA rookie scale salary cap would have allowed him to make with the
San Antonio Spurs at that time. On June 7, 2008, the
San Antonio Express-News reported that Spurs General Manager
R.C. Buford, had stated that Splitter had informed the team that he would not be coming to San Antonio for the
2008–09 NBA season. Splitter had instead signed an extension with Saski Baskonia, that would keep him in the Spanish ACB League through 2010. It was announced on July 9, 2010, that Splitter had opted out of his contract with Saski Baskonia, in order to sign in the NBA with the San Antonio Spurs.
San Antonio Spurs (2010–2015) On July 12, 2010, Splitter signed a contract with the San Antonio Spurs. The deal was believed to be worth $11 million over three years. He earned his first start of his
NBA career on March 19, against the
Charlotte Bobcats, in place of the injured
Tim Duncan. In this game, Splitter recorded eight points and six rebounds. On February 8, 2012, Splitter and teammate
Kawhi Leonard, were selected to play in the
2012 Rising Stars Challenge. On February 17, it was revealed that both Splitter and Leonard would be teammates for Team
Chuck. However, due to an injury, he was released from Team Chuck and was replaced by
Derrick Favors. On May 29, 2012, in Game 2 of the Western Conference Finals,
Oklahoma City Thunder head coach
Scott Brooks attempted to slow San Antonio's offense through continually fouling Splitter, sending him to the free throw line with the "
Hack-a-Shaq" strategy. He played his most productive season with the Spurs in
2012–13, averaging 10.3 points and 6.4 rebounds per game, while playing all but the final game of the regular season. He started 58 games, as the Spurs finished the West as the two-seed, behind the Oklahoma City Thunder. The Spurs would advance to the
2013 NBA Finals, only to lose to the
Miami Heat in seven games, as Miami won their second straight NBA championship. On July 13, 2013, he re-signed with the Spurs. On June 15, 2014, Splitter won his first NBA championship, after the Spurs defeated the Miami Heat, 4 games to 1 in the
2014 NBA Finals. After missing 20 out of the first 21 games of the
2014–15 season with a back injury, Splitter played out the rest of the season, until missing the final six games of the regular season, with a calf injury. He returned for the playoffs, but the Spurs were knocked out in the first round by the
Los Angeles Clippers, in seven games.
Atlanta Hawks (2015–2017) On July 9, 2015, Splitter was traded to the
Atlanta Hawks, in exchange for the draft rights to
Georgios Printezis, and a future second-round pick. On February 16, 2016, he was ruled out for the rest of the season, after electing to have surgery to repair his right hip. On October 11, 2016, Splitter was ruled out for four weeks with a grade 2 hamstring strain. He was ruled out for a further six weeks, on November 26, after an
MRI exam revealed a grade 2 right calf strain.
Philadelphia 76ers (2017) On February 22, 2017, Splitter was traded, along with a second-round draft pick, to the
Philadelphia 76ers, in exchange for
Ersan İlyasova. On March 21, 2017, he was assigned to the
Delaware 87ers, the 76ers'
D-League affiliate. He was recalled six days later. On March 28, 2017, he made his debut for the 76ers, recording two points and three rebounds, in seven minutes of playing time, in a 106–101 win over the
Brooklyn Nets. Splitter, who had been nursing a right calf injury, entered the game late in the first quarter, and played in his first game since January 31, 2016, when he was a member of the Atlanta Hawks, before undergoing hip surgery. He played a handful of games with a prosthetic hip.
Retirement On February 19, 2018, Splitter announced his retirement from playing professional basketball, due to a hip injury that had hindered the back-end of his career. On May 5, 2024, Splitter's jersey number 21 was retired by Saski Baskonia. ==National team career==
