Isaac Frost tested the skills of Sagat Jr. to make sure he was ready to compete in Pride FC.  The Muay Thai heavyweight proved he can be a contender.  In the first sparring session, Sagat showed he was able to go 3 rounds before eventually getting the finish.  In the second sparring session, Sagat finished him at the end of the 1st round with a crispy left-right hook combo.

However, if these ever meet in Pride FC, the results may be different.
