The Orioles signed Taiwanese pitcher Chen Wei-Yin:

The deal, which is pending physical, is likely for three years, though the third year could be an option that vests, according to the source.

His career stats from NPB are here. It looks like he has an excellent walk rate, and a K/BB over 3:1. His ERA stands well below the league ERA in each of the last four years. Looks like the Orioles are thinking outside the box here.
