The Roger Clemens trial took a turn on Friday morning as the prosecution tested cotton balls which was stored stored in a beer can by Brian McNamee for seven years. The results from testing those cotton balls confirmed a Clemens match.
The test was done by Alan Keel who is a DNA forensic scientist, and the odds that it would be a match is extremely rare. Here is a series of tweets describing what was found with testimony from Keel:

Keel also attempted to test a needle that McNamee had but there was no biological material to perform a test.
