Just signed up on MTF and committed to Indian Wells. Will I get a spot in the qualifying draw?
No. There are already 64 players in QD. Sorry. You could withdraw and commit to Santiago, but you'd be Late Entry there and small chances to get a QD spot, too. So probably you should stay here as ALT and hope to have the chance to enter QD this way.
It's a bad week to start TT, with only 2 tournaments.
