This isn't the first time that ex-major league pitcher Bruce Chen has donned a national team jersey to play in the World Baseball Classic. The left-hander competed for his native Panama in the first two tournaments in 2006 and 2009.

Now the 39-year-old is back at the global baseball championship with a different look: a vivid red Chinese national team jersey, and with a whole new mindset.

Chen hung up his glove in 2015, but returned to the diamond to contribute to the country where he has his roots in the fourth edition of the Classic.
