The tweet is apparently from his dad...
translation:
My tall son, who has been working persistently, received his first invitation to the University today, reaching beyond anyone's reach in the country of Basketball.
My son's reaching this height at the age of 16 shows how much potential he has.
I don't know if there's a naming convention in Mongolian, something else with the translation, or if there is a half or stepbrother factor, but the dad has a lot of stuff on his Twitter about Mike Sharavjamts at San Francisco who transferred from Dayton. Apparently dad was also the first Asian Harlem Globetrotter.
Ghana is a teammate of Jon Sanderson Jr. at Saline. I don't think Ghana played this past year as it looks like there was a lot wrapped up in transfer rules.
