Along with outfielder Joc Pederson who did it in AAA in 2014, he is one of only two LA Dodger minor leaguers to have a 30 home run, 30 stolen bases season. in 2005 Chen became the first Taiwanese baseball player to play in Major League baseball when he made his debut on September 14, 2002. He played for the Los Angeles Dodgers in parts of the 2002-05 seasons, but only sparingly. In 2005, Chen was reluctant to accept a designation for assignment back to Dodgers' Las Vegas 51s AAA team, and try out with another major league team. In 2005, Chen was the first Taiwanese position player to ever get a hit in Major League Baseball, a 2-run RBI single off Colorado Rockies' reliever Bobby Seay. However, Chin-hui Tsao had earlier become the first Taiwanese player to get a hit in the Majors as a pitcher, with the Colorado Rockies on August 18, 2003. in 2005 After his contract with the Dodgers organization expired after the 2005 season, Chen announced on December 26, 2005, that he would not return to North America for the 2006 season, but would instead enter the CPBL draft. In 2006, after struggling to make the 25-man roster with the Dodgers, Chen tried out for the Japanese professional league, and eventually decided to play in the Chinese Professional Baseball League in Taiwan. He was promptly selected by the La New Bears as a designated hitter. Chen had completed his first complete baseball season at the hometown Taiwan in 2006. He ranked first in many aspects such as the highest batting average and 81 RBIs for the whole season. He also led the Bears to the championship title and he won his first MVP title for the final series matches. Later on in the second Asian baseball tournament, he showed the best performance again and gained attention from several Japanese and Korean teams, including the Orix Buffaloes. But, Chen did not sign with them and remained in Taiwan. Chen announced his retirement from the Chinese Professional Baseball League on September 18, 2016. On September 18, 2016, at the conclusion of his final match, Lamigo Monkeys retired his #52 jersey.
