Pittsburgh Pirates Wang signed as an international
free agent with the
Pittsburgh Pirates in 2011. When the Pirates discovered that Wang required
Tommy John surgery, they voided the contract, and signed Wang to a new contract. Wang competed for a spot on the Brewers' 2014
Opening Day roster, which he made. Wang made his MLB debut on April 14, 2014 against the
St. Louis Cardinals pitching a scoreless inning, allowing one hit. During the 2015 season, Wang pitched for the Advanced-A
Brevard County Manatees. He was designated for assignment by the Brewers on June 16, 2015. After three years in the minor leagues, the Brewers recalled Wang from
Colorado Springs Sky Sox on July 30, 2017. He was granted his release from the
Milwaukee Brewers in order to pursue a playing opportunity in South Korea, and was released on January 26, 2018.
NC Dinos Wang was the first Taiwanese baseball player to play in the South Korean
KBO League. He signed a one-year contract for $700,000 with the
NC Dinos of the
KBO League. The contract was announced by the Dinos on January 26. He became a free agent following the 2018 season.
Oakland Athletics On February 1, 2019, Wang signed a minor league deal with the
Oakland Athletics that included an invitation to
spring training. On May 25, his contract was selected and he was called up to the major leagues. Wang became the first Taiwanese player in Athletics' franchise history three days later, when he pitched two scoreless innings against the Los Angeles Angels, allowing only one hit. On July 4, Wang earned his first MLB win, tossing shutout innings in a 7–2 victory over the
Minnesota Twins, during which he allowed one walk, no hits, and one strikeout. However, Wang struggled to establish himself as a reliable option outside of mop-up duty, and was optioned to the Triple-A
Las Vegas Aviators on August 19, with a 3.33 ERA buoyed almost entirely by a microscopic 0.231 average against on balls put in play. On August 29, Wang was designated for assignment.
Pittsburgh Pirates (second stint) On August 31, 2019, Wang was claimed off waivers by the
Pittsburgh Pirates. He earned wins twice as a reliever. His MLB stats during the 2019 season was 3–0, with ERA 3.77 in 25 appearances. Wang was outrighted off the Pirates roster on November 2 and became a free agent two days later.

Wei Chuan Dragons in the 2020
Chinese Professional Baseball League draft, and returned to his native Taiwan as the first left-handed pitcher to be chosen with the first pick in the CPBL draft. In September 2020, Wang signed a 5-year, $2.08 million USD contract with the Dragons, the largest contract in Taiwanese professional baseball history. On March 14, 2021, Wang made his CPBL debut as the Dragons'
Opening Day pitcher against the
Uni-President 7-Eleven Lions. Wang pitched in the 2023
Taiwan Series, being the losing pitcher in Game 2 after allowing 4 hits and 2 walks and 4 earned runs across 2/3 innings. Wang also pitched 1 1/3 innings in Game 5, allowing 4 hits, including 1 home run, giving up 3 runs. After accumulating a 15–26 win-loss record and a 3.64 ERA across 5 seasons, Wang requested to be excluded from the Dragons' 60-man roster after the 2025 playoffs, and was non-tendered by the Dragons after the 2025 season.
