This time, reportedly, it's infielder Chan-Jong Moon out of Korea, for $350,000.
From Zachary Levine:
The Astros would not confirm this, but a person with knowledge of the situation told me that the process of making him an Astro should continue when he is brought to the U.S. in September.
If you read Korean, read it, and let us know what it says.
It's actually amazing how little Google comes up with when you search for Chan-Jong Moon.
