Márcio Carlsson

Carlsson was a member of the Brazilian team which won the Sunshine Cup in 1993, which was their first title since 1958.[3] He and Gustavo Kuerten won the deciding doubles rubber over the Chilean pairing of Marcelo Ríos and Robinson Gamonal.[4] Earlier in the year, Carlsson had partnered Rios in the French Open boys' doubles event and the pair made the semi-finals.[5] This helped Carlsson finish the season ranked sixth in the world junior doubles rankings.[5] His usual junior doubles teammate however was Kuerten and the pair would also partner each other at Challenger tournaments in 1994 and 1995.[5]

The Brazilian had his best year on tour in 1998. He defeated seventh-seed Grant Stafford at the U.S. Men's Clay Court Championships, before exiting at the quarter-finals, then upset the man who had won that tournament, Jim Courier, in Atlanta.[5] In the lead-up to his meeting with Courier, Carlsson had to play in six qualifying matches. Courier was up a break in the third set, but Carlsson came back to defeat the world number 39.[6] He also beat two top-100 players, Ramón Delgado and Lucas Arnold Ker, at a Challenger tournament that year, which was held in the city of his birth, Florianópolis.[5] On the doubles circuit that season, he had his best result at the Croatia Open, where he and Cristian Brandi made the semi-finals.[5]

In 1999, Carlsson made his only Davis Cup appearance for Brazil. With his team having already secured their World Group tie against Spain, Carlsson played a dead rubber match against Àlex Corretja, which he lost.[7] He also took part in the 1999 Australian Open and was beaten in the opening round by Mariano Puerta, in four sets.[5]
