A great comeback, as he was 0-2 down at one point of time.
Another good performance, as he beat someone ranked than 143 places above him.
He was due to play the second seed, but Estonian Jaak Poldma upset him in three sets.
Poldma is ranked 31, and thus is a near unbeatable opponent.
But Cox has beaten the world numbers 31 and 14, so he has a slim chance.
Almost impossible though.....
