Very lucky loser

As part of the Sony Ericsson Open 2009, the German Bjorn Phau have won 45 points and $20,400. Why? Here we have the equation:

Qualifying Draw

(5)Bjorn Phau d. (WC)Michael McClune (459º USA) 4-6 6-0 6-1
John Isner d. (5)Bjorn Phau 2-6 7-5 6-3

Main Draw Singles - Second Round
[LL] B Phau * d A Montañes (ESP) 6-4 2-0 and ret. (hamstring)
* Replaces [24] R Gasquet (FRA) – shoulder

Easy? Not sure. But it seems that Bjorn is a very very lucky loser...
