He will also become the first local player to sign multi-year contract with an MLB team.
Chien-ming Wang 王建民 of the Washington Nationals had previously sought a multi-year contract during his years with the New York Yankees failed in the attempt.
Chen's reported deal with the Orioles pays him just under US$4 million a year and therefore does not rank as the highest single-year salary paid to a Taiwanese player in the U.S.
That record is still held by Wang, who made US$5 million (NT149 million) in 2009 in his last year with the Yankees...
Chen is also the first Taiwanese player to be signed by the Baltimore team.
Though the Orioles hope Chen will fit into their starting rotation, the Taiwanese lefty will face stiff competition, with eight pitchers potentially vying for only five starting slots.
Though their teams are in different leagues, Baltimore and Washington are natural geographic rivals, and should meet every season (especially from 2013, when the Houston Astros move from the National League Central to the American League West). Should Wen make the Orioles' rotation, you can expect a great deal of local interest when his team and the Nationals play each other.
