Wei-Yin Chen[2] (Chinese: 陳偉殷; pinyin: Chén Wěi-yīn; born July 21, 1985) is a Taiwanese professional baseball pitcher who is a free agent. He has played in Major League Baseball (MLB) for the Baltimore Orioles and in Nippon Professional Baseball (NPB) for the Chunichi Dragons.

Early life[edit]

Wei-Yin Chen was born in Kaohsiung County, Taiwan. He attended Ciao-Tou Junior High School[3] and Kaoyuan Vocational High School, which was also attended by current Los Angeles Dodgers pitcher Tsao Chin-Hui, among other Chinese Professional Baseball League players.[4]


Chunichi Dragons[edit]

Chen played for the Chinese Taipei National Team in the 2004 and 2008 Olympic Games.[5] He was a pitcher for the Chunichi Dragons in Nippon Professional Baseball (NPB) from 2004 through 2011. Chen had Tommy John surgery at the end of 2006 season.[6] His best season in Japan came in 2009 when he posted a 1.54 earned run average (ERA) to lead the league.[4] When he came out of the Nippon League, FanGraphs described him as being an extreme control pitcher with poor velocity.[7] A clause implemented into his contract with Chunichi allowed him to opt out after the 2011 season at age 26.[7]

Baltimore Orioles[edit]

2012 season[edit]

After the 2011 season, Chen signed as an international free agent with the Baltimore Orioles.[8] Chen was the first Taiwanese player ever signed by the Orioles.[9] He made his MLB debut on April 10, 2012 against the New York Yankees in Baltimore. The game was broadcast live on national television in native Taiwan,[10] and Chen totaled 523 innings and gave up two earned runs striking out six in a no-decision that the Orioles would later go on to lose in extra innings.[11] In total, Chen finished the season leading the team with 32 starts during which he totaled 12 wins and 11 losses and posted an ERA of 4.02 in 192.2 innings pitched.[12] In 2012, Chen was "the only constant in the (Orioles) rotation" and was consistent throughout the year.[13]

2013 season[edit]

Coming out of spring training, Chen won the number two spot in the Orioles' starting rotation behind Jason Hammel.[14] Chen set a goal to throw 200 innings on the season. In his first three starts, he lacked run support and went 0-2 despite posting a 4.00 ERA.[15] On May 15, 2013, the Orioles placed Chen on the disabled list, his first-ever stint there, with an injury to his right oblique.[16] In his return from the disabled list on July 10, 2013, Chen pitched seven innings in a matchup against the Texas Rangers striking out four and allowing three hits, earning the win.[17] Overall in 2013, Chen finished 7-7 with a 4.07 ERA in 23 starts. During the 2013 off-season, Chen underwent knee surgery to remove bone spurs.

2014 season[edit]

Chen pitched a season-high of eight strikeouts in a win against the Seattle Mariners on August 1, 2014. He dedicated the win to victims of the 2014 Kaohsiung gas explosions, which occurred hours earlier in his hometown.[18] On September 10, Chen picked up his 15th win of the season against the Boston Red Sox and carried a perfect game into the sixth inning until Dan Butler's first major league hit.[19] Chen finished the season with a 16-6 record and 3.54 ERA over 185 2/3 innings.[20] In game 3 of the 2014 ALCS on October 14, Chen pitched 5 1/3 innings on 80 pitches and gave up 2 runs in a loss against the Kansas City Royals. Chen became the first Taiwanese pitcher to start an ALCS game.[21]

2015 season[edit]

On June 26, 2015, Chen became the second Taiwanese-born player to have 100 career starts in the major leagues, allowing two runs and striking out five over six innings in a no decision against the Cleveland Indians.[22]

Despite only recording a 4-5 record at the break, Chen pitched to a 2.78 ERA and 1.09 WHIP, along with 90 strikeouts in 110.0 innings over the first half of the season. Chen finished the season with a 11-8 record and a career-best 3.34 ERA over 191 1/3 innings pitched.[23]

Scouting report[edit]

An "extreme flyball pitcher",[24] Chen pitches from a three-quarters arm slot and throws a four-seam fastball averaging 91-92 mph.[25] In addition, he throws a two-seamer, a slider, a changeup, and an occasional curveball.[25] Since he previously pitched in Japan where he started on five days rest rather than four, with the Orioles he initially had durability issues and was 0-4 in his last seven starts in 2012.[26] Chen has been described as a legitimate middle-of-the-rotation starter.[27][28] An opposing scout said, "I watched Wei-Yin Chen and swore I was watching Tom Glavine. He has such an effortless delivery and an above-average change up, and knows how to pitch inside."[29]


In 2012, Chen started a baseball scholarship program for Taiwanese students, contributing funds based on statistical milestones reached per season. He expanded the charity's efforts in 2015, to cover animal protection and children's welfare.[3]
