It's sink or swim time for Russell Knox, pictured above, on the US PGA Tour.
Sadly, the Inverness-born resident of Jacksonville Beach, Florida seems to be sinking in the second round even though a par 72 is not a bad effort. 
But a par round on the highly competitive US Tour usually means you lose ground, and a lot of it, because most of your fellow competitors are in sub-par mode.
This is the last event to county for the US Tour money table. At the end of it, those not in the top 125 of the table have to go back to school, Stage 2 of the US Tour Q School to be precise.
Knox is outside the top 125 and needs a top-10 placing at least to survive in the Big League.
