New York Yankees 2005–2007 Wang made his MLB debut on April 30, 2005, against the
Toronto Blue Jays, pitching seven strong innings while allowing only two earned runs. He earned a no-decision in the Yankees' 4–3 win. Wang pitched in 18 games, though an injury kept him sidelined for part of the season. He went 8–5 with an
earned run average of 4.02. On September 19, 2005, Wang tied a record for
assists in a game by a pitcher with nine. In the
playoffs against the
Angels, Wang pitched 6 innings and allowed four runs, only one of which was earned. The Yankees lost the game and the series. In 2006, Wang won 19 games (tied for the most in the majors along with
Johan Santana) and posted a 3.63 ERA in 218 innings across 34 games (33 starts). He picked up his first save on June 3 against the
Baltimore Orioles in his only non-starting appearance. Wang also threw two complete games, though the first, on June 18, was bittersweet: against the
Washington Nationals, he allowed a one-out, two-run, walk-off home run by
Ryan Zimmerman to lose the game 3–2. His first complete-game win was on July 28, 2006, a two-hit, 6–0 shutout of the
Tampa Bay Devil Rays at
Yankee Stadium. In his next start, he threw eight shutout innings against the
Toronto Blue Jays, in which he got an outstanding 16 ground ball outs. Wang was particularly strong in the second half of the season, winning 10 of his 14 starts and posting a 3.13 ERA in 92 innings. He was selected to start the first game of the
Division Series against the
Detroit Tigers, earning the win as the Yankees beat Detroit 8–4. Overall in 2006, Wang limited batters to a .211 batting average while games were tied, and a .205 batting average in games that were late and close. The
Tampa Bay Devil Rays batted just .159 against him, losing three out of four games to the Yankees that Wang pitched. Wang was effective despite the lowest strikeout rate in the majors (3.14 strikeouts per nine innings and 76 strikeouts overall), thanks in part to his allowing the fewest home runs per nine innings (0.5; he allowed just 12 home runs overall). and obtained 2.84 groundouts for every fly ball out. At the end of the season, Wang finished second to Johan Santana in voting for the
Cy Young Award. Wang collected 15 second-place votes, and 51 points. He also received a ninth-place vote, good for two points, in the
AL MVP balloting, won by
Justin Morneau. In
MLB.com's This Year in Baseball Awards, he was chosen as the top starter in 2006 season with more than 47% of the fan vote. Wang began the 2007 season on the
disabled list, having injured his right hamstring during spring training. He returned on April 24 against Tampa Bay. On May 5, 2007, Wang pitched 7 perfect innings before giving up a home run to
Ben Broussard of the Seattle Mariners, falling five outs short of a
perfect game. On June 17, 2007, Wang had a superb outing versus the
New York Mets, in which he threw 113 pitches through 8 and 2/3 innings, notched 10 strikeouts (a career high) and gave up just two runs on six hits. On August 30, Wang took a no-hitter against the
Boston Red Sox into the seventh inning before giving up a single to
Mike Lowell. Rookies
Joba Chamberlain and
Edwar Ramírez finished the two-hitter, and the Yankees beat the Red Sox 5–0. In 2007, Wang was second in the AL in wins (19), third for the second straight year in win–loss percentage (.731), ninth in wild pitches (9), and 10th in hit batsmen (8). He had a perfect 1.000 fielding percentage. He also had the lowest HR/9 innings pitched ratio in the AL (0.41; in innings he allowed just nine home runs), was third in GB% (58.5%) and GB/FB (2.51), and had the fifth-lowest strikeouts per 9 innings pitched (4.70, and 104 strikeouts overall). Despite his regular season performance, Wang faltered in the 2007 postseason. In the
American League Division Series against the
Cleveland Indians, Wang started two games, earning the loss in both appearances. He pitched a combined 5 and 2/3 innings, giving up 12 earned runs, for a postseason ERA of 19.06. The Yankees lost the ALDS in four games.
2008–2009 The beginning of the 2008 season saw Wang at the top of the Yankees rotation and the ace with veterans
Mike Mussina and
Andy Pettitte. In the final
Yankee Stadium season opener against the Toronto Blue Jays, Wang pitched 7.0 innings, allowing only two runs and picking up his first win of the season. In his first start against the
Boston Red Sox in 2008, he pitched a one-run, two-hit
complete game. On April 22, 2008, Wang recorded a win against the
Chicago White Sox at
U.S. Cellular Field. The victory, in Wang's 85th career start, made him the fastest Major Leaguer to record 50 wins as a starter since
Dwight Gooden, who won his 50th game in his 82nd start on June 29, 1986, at Chicago for the New York Mets. Wang also became the quickest Yankee to 50 wins since
Ron Guidry, who accomplished this in his 82nd start. Wang finished April with a perfect 5–0 record, leading the American League along with
Joe Saunders. On May 2, Wang became the first six-game winner in the American League with a win over the
Seattle Mariners with just one earned run over six innings. On May 8,
Cliff Lee of the
Cleveland Indians beat Wang 3–0, handing Wang his first loss of the season. During this loss, Wang allowed three runs and five hits in seven innings. On June 10, after going six starts with two losses and four no decisions since May 2, Wang defeated the
Oakland Athletics 3–1 to end the longest victory drought of his career. Through 2008, Wang had the third highest winning percentage of all starting pitchers over the last three years (46–15, .754). On June 15, Wang was taken out of an interleague game versus the
Houston Astros due to a right foot injury he sustained while running the bases, something he was not used to doing, since pitchers do not bat in the American League. Wang was diagnosed with a torn
Lisfranc ligament of the right foot and a partial tear of the
peroneus longus of the right foot. Despite not requiring surgery, he was on
crutches and wearing a protective boot. The cast was removed on July 29, but the extensive rehabilitation process prevented Wang from pitching for the remainder of the season. Yankees' part-owner
Hank Steinbrenner showed frustration with pitchers having to bat in the National League and suggested that the League "join the modern age". On December 22, 2008, Wang and the New York Yankees avoided salary arbitration when they agreed to a $5 million, one-year contract. Wang made $4 million in the 2008 season after losing in salary arbitration. He had asked for $4.6 million. On April 3, 2009, Wang became the first Yankees' starting and the first game winning pitcher of the new
Yankee Stadium in the stadium opener
exhibition game against
Chicago Cubs. His regular season began with an extraordinarily bad performance. In his first start of the regular season, Wang gave up seven earned runs and nine hits in 3.2 innings against the
Baltimore Orioles. That was followed by a one-inning appearance against the
Tampa Bay Rays when he surrendered eight earned runs in just one inning. In his third start, against the
Cleveland Indians in New York on April 18, Wang was credited for eight more earned runs in 1.1 innings; Cleveland won the game 22–4. After his first three appearances, Wang was 0–3 with a whopping 34.50 ERA. On April 22, General Manager
Brian Cashman, at a Q&A at
Southern Connecticut State University, confirmed Wang's release point was five inches higher than the same time the previous season. After being removed from the rotation and sent down to
Tampa to work out mechanical issues, Wang was diagnosed with weakness in the muscles of both hips and placed on the disabled list. He was activated from the disabled list on May 22, 2009, and on his first day on the active roster, he was brought in from the bullpen. After two more relief appearances, Wang went back to the rotation, but he struggled once again in his first and second starts back. On June 28, Wang earned his first win of the season, also his first since June 15, 2008, giving up two runs over 5.1 innings against the
New York Mets. Wang was placed on the disabled list on July 15, 2009, due to shoulder soreness. He was then eliminated for the remainder of the season after undergoing shoulder surgery on July 30, 2009. After the Yankees won the
2009 World Series against the
Philadelphia Phillies, Wang participated in the championship parade through the
Canyon of Heroes, but acknowledged it "would have been more fun" if he had been healthy. On December 12, 2009, the Yankees made the choice not to re-sign him, making him a free agent.
Washington Nationals 2010–2012 On February 19, 2010, the
Washington Nationals announced they had signed Wang as a free agent to a $2 million deal (plus up to $3 million in incentives). In June, it was thought that Wang would return to the majors in late July or early August. However, Wang's rehabilitation had been inconsistent, and there was no timetable for his return to the majors. In September, the Nationals acknowledged that Wang would not pitch in the majors at all during the season, but instead was preparing for the instructional leagues in the fall. Wang was non-tendered after the 2010 season. On December 16, 2010, Wang re-signed with the Nationals to a one-year, $1 million contract with $4 million worth of potential performance incentives. After continuing his injury rehabilitation, he began a formal rehab assignment on June 27 with the Nationals' Class A farm team, the
Hagerstown Suns, pitching three innings, allowing two earned runs while striking out three and walking none. Although his velocity topped out at around 90 mph, it mostly sat between 86 and 88 mph. In his second start, on July 2 with the high-A
Potomac Nationals, Wang pitched four shutout innings, and allowed two walks while striking out two. 63% of his 38 pitches were strikes while his velocity hit 91 mph in his final inning of work. Following a July 24 start for the Triple-A
Syracuse Chiefs, Wang made his Nationals debut on July 29. Wang ended the season with 11 starts, recorded 4–3 with a 4.04 ERA. He also made his first hit and first RBI in the majors in his final start of the season on September 24 against the
Atlanta Braves' starting pitcher
Brandon Beachy. On October 30, 2011, Wang was granted free agency. Five days later on November 4, Wang re-signed with the Nationals to a one-year, $4 million contract. On March 15, 2012, Wang sustained an injury to his left hamstring, placing him on the DL. On May 25, Wang pitched in the majors for the first time since going on the disabled list. He went three innings in his first win that season. Wang then replaced
Ross Detwiler in the team's starting rotation. In just four starts, Wang went 1–3 with an ERA of 6.10 and 11 strikeouts. On September 23, Wang hit his first career double against
Milwaukee Brewers' starting pitcher
Yovani Gallardo.
Minor league stint with the Yankees On March 22, 2013, Wang signed a minor league contract with the New York Yankees. According to his agents and Taiwan's EETV, his minors contract is worth US$35,000 per month, but could worth up to $2.5 million per year, with an extra $2.2 million in bonuses. However, if he did not secure a major league contract by the end of April, he had the option to revert to free-agent status. Wang opted out of his contract on June 7, 2013.
Toronto Blue Jays Wang signed a one-year, $500,000 deal with the
Toronto Blue Jays on June 9, 2013. He was added to the Blue Jays' roster on June 11, making his first pitching appearance as a starter against the
Chicago White Sox. Toronto Blue Jays general manager
Alex Anthopoulos said that the team guaranteed Wang one start, and would decide on further appearances based on the result of his first start. Wang earned his first win as a Blue Jay in a game against the
Texas Rangers on June 16, pitching seven shutout innings. The win gave the Blue Jays their first four-game sweep in the 2013 season, and the first four-game sweep of the Rangers in
Arlington in Blue Jays franchise history. From June 11, the date Wang was added to their roster, to June 23, the Blue Jays went on an 11-game winning streak. Wang started three games during the streak, pitching at least six innings in each and compiling an ERA of 2.18. Wang followed up his successful streak by starting two games in which he was unable to make it out of the second inning. On June 27, Wang pitched 1 innings against the Boston Red Sox and surrendered six hits and seven earned runs. On July 2, he also pitched only 1 innings and gave up eight hits and six earned runs to the
Detroit Tigers. After the Tigers game, Blue Jays manager
John Gibbons announced that Wang had been
designated for assignment. Wang was reported to be willing to accept an assignment to Triple-A
Buffalo and was outrighted to Buffalo on July 5. Wang was added to the Blue Jays roster again on August 24, and designated for assignment on August 26. After clearing waivers, he was again outrighted to the Buffalo Bisons. He became a free agent on October 1.
Return to the minor leagues On December 19, 2013, Wang signed a minor league contract with an invitation to
spring training with the
Cincinnati Reds. He began the 2014 season with the
Louisville Bats of the International League, but opted out of his deal on July 13. Wang signed a minor league contract with the White Sox on July 17, and pitched for the
Charlotte Knights of the International League. During the 2014–15 offseason, Wang signed a minor league contract with the
Atlanta Braves. The Braves assigned Wang to the
Gwinnett Braves of the International League. In 10 starts and one relief appearance, Wang had a 2–6 record with an ERA of 6.10, while surrendering the most hits in Triple-A up to the month of June. He was released on June 19. Wang signed with the
Southern Maryland Blue Crabs of the
Atlantic League of Professional Baseball, an
independent baseball league, on June 24. He made three starts for the Blue Crabs, winning all three and pitching to a 2.49 ERA. On July 12, 2015, Wang signed a minor league contract with the
Seattle Mariners. They assigned him to the
Tacoma Rainiers of the Triple-A
Pacific Coast League.
Kansas City Royals On January 7, 2016, Wang signed a minor league contract with the
Kansas City Royals. After a strong spring training, he made the Royals' opening day roster for the
2016 season as a relief pitcher. On April 9, 2016, Wang threw a scoreless ninth inning in a 7–0 victory against the
Minnesota Twins. This was his first major league game since August 25, 2013. Wang pitched for the Royals 38 times for innings over the year, going 6–0 with a 4.22 ERA. He went on the disabled list with right biceps tendinitis on August 31 and was designated for assignment on September 17, 2016. He was released on September 22. ==National baseball team==
