Since the main draw of ATP Alphen starts only on tuesday and quallies on sunday the 2nd deadline for singles and double will be extended until saturday 6:00pm CEST.
I will post an updated entry list with all players marked who are still in US Open by that time as well
Maybe the deadline for doubles will be extended even further depending on the number of teams
Note: You have to be out of TT US Open by saturday 6:00pm if you want to play in the quallies here.
You have to be out of TT US Open by monday if you want to play in the main draw here.
