OHHHH MYYYYYYY GOOOOOOOD. I think 4 (maybe 5) people can still win this.
1/ Matthew needs Murray to win the tournament.
2/ Dupuis needs Gasquet to beat Berdych and Murray to not win the tournament.
3/ Jervis needs Berdych to beat Gasquet and Murray to beat Berdych and Murray to lose the final.
4/ Brick Top needs Berdych to beat Gasquet and Murray.
Not sure if someone picked Gasquet to beat Berdych + then Murray to win tournament, if so, they will probably take over Matthew?
Plenty of places up for grabs with Djokovic and DelPo's demise.
So if Murray wins the tournament then I win, as simple as that?
