Pedro Diogo Tavares Martins de Oliveira is a Portuguese swimmer, who specialized in backstroke and butterfly events. He is a two-time Olympian, and a double silver medalist in the 200 m backstroke at the European Junior Championships. He also holds four Portuguese records, two national titles, and has produced a stellar performance at the NCAA Swimming Championships, earning five All-American titles as a member of Louisville Cardinals.
In 2007, Oliveira made his official debut as a senior swimmer at the FINA World Championships in Melbourne, Australia. He failed to reach the top 8 final in the 200 m backstroke, finishing in fourteenth place with a time of 2:01.18. Earlier in the prelims, Oliveira set a new Portuguese record of 2:00.62 to guarantee a slot for the semifinals. At the 2008 European Aquatics Championships in Eindhoven, Netherlands, Oliveira experimented with the 200 m butterfly, where he posted a lifetime best of 1:59.00 in his semifinal run, sinking Diogo Carvalho's Portuguese record by 0.67 of a second. Four months later, at the 2008 Summer Olympics in Beijing, Oliveira failed to reach the top 16 in any of his individual events, finishing twenty-fourth in the 200 m butterfly, and twenty-eighth in the 200 m backstroke. At the 2009 FINA World Championships in Rome, Italy, Oliveira maintained his official lineup in the program, swimming only in two individual events. In the 200 m butterfly, Oliveira broke a new Portuguese record of 1:56.17 to secure his semifinal spot with an advantage of a polyurethaneswimsuit, slashing off Carvalho's standard by a 0.65-second deficit. In his second and final event, 200 m backstroke, Oliveira could not match his stellar performance from the butterfly, finishing thirty-second in the prelims with a time of 2:01.49. In 2010, Oliveira reached his breakthrough in swimming, when he claimed a 200-metre butterfly title at the USA Swimming Grand Prix in Austin, Texas with a time of 1:59.02. His unexpected triumph from the meet moved him up to sixth in the world rankings. In 2011, Oliveira decided to skip the World Championships to focus on his swimming career for the Louisville Cardinals. However, he later appeared in a global spotlight after earning a third spot in the 200 m butterfly at the AT&T Winter National Championships in Atlanta, Georgia. Oliveira also competed for Portugal at the 2011 Summer Universiade in Shenzhen, China, where he placed ninth in the 200 m butterfly at 1:58.50, just missing out the final by a small fraction of a second. At the 2012 Summer Olympics in London, Oliveira competed in the same individual events with only two days in between. He achieved FINA B-standards of 1:59.72 from the European Championships in Debrecen, Hungary, and 1:58.50 from the Summer Universiade in Shenzhen, China. In his first event, 200 m butterfly, Oliveira placed twenty-second on the morning preliminaries. He powered past the entire field to lead the second heat in a personal textile best of 1:58.45. Two days later, in the 200 m backstroke, Oliveira challenged seven other swimmers in the same heat, including Hungary's Gábor Balog, finalist at the European Championships. He set a new Portuguese record of 1:58.83 to earn a second spot behind Balog. Oliveira missed the top 16 semifinals by six-tenths of a second, as he placed twentieth in the prelims. Three months after the Olympics, Oliveira placed sixth in the 200 m backstroke at the 2012 European Short Course Swimming Championships in Chartres, France in a Portuguese record of 1:53.06. On May 10, 2013, Oliveira was chosen as one of elite swimmers to land a sponsorship deal with FINIS, a world leading company in technical swimming products.
