Pro tour

Wang turned pro in 2003 and has improved his game and ranking year each he has been on the professional circuit. In 2005, Wang broke into the ATP Top 100 for the first time by virtue of three straight Challenger final appearances, winning a title at Istanbul, Turkey. The 21-year-old also reached the quarterfinal round of the ATP event in Bangkok, Thailand, and lost to Rafael Nadal in the 1st round in Beijing, China at the China Open. Wang made his Grand Slam debut at Wimbledon in 2004, losing to Andy Roddick in the first round. In 2006, he reached the second round, bowing out to James Blake 3 sets to 1.

Wang's best Grand Slam performance to date came at Wimbledon in 2014, where he defeated Alejandro González and Mikhail Youzhny to advance to the third round, ultimately losing to Jo-Wilfried Tsonga.

He was a member of the Chinese Taipei Davis Cup team, compiling a 17–6 record in Davis Cup action since 2001.

Near the end of his career, Wang took breaks from competing due to a persistent wrist injury. With several years of recovery, he decided to play in doubles while helping out the young players. He was content with the results during 2019 and briefly considered making a comeback for some time. However, Wang got tired of traveling around the world to train and compete, which made him start thinking about retirement from professional tennis. His decision was strengthened after getting married and the birth of his child, and Wang eventually started focusing on other things.^[1] In September 2019, he played his last match at the 2019 OEC Kaohsiung in doubles with Hsu Yu-hsiou.
