According to the minor league transactions page on Baseball America, the Pirates have signed Taiwanese pitcher Jen-Lei Liao to a minor-league deal.
Liao born and raised in Taiwan, but somehow pitched in Japan, for Okayama Kyosei high school in 2010 and 2011 season. He went back to his country, and played for Kainan University last two years.
The 20-year-old righty has a huge 6' 6", 264 lb frame. However, he is not a hard wine&cheese thrower like Luis Heredia. Liao's fastball sits at around 88 MPH and tops out 92 MPH and he mixes it with a curve and forkball. He has trouble repeating his delivery.
Obviously, he is really raw. He still could add to his fastball velocity because of his size/frame though.
Here're his profile and videos.
