If you applied to play on a USA Senior International Team for 2017 (Miami), you can now check the list to make sure your name is on the list (and check out who else is interested in playing). If your name is omitted and you applied for a team in a timely manner, you have till May 10th to notify the USTA of that omission.
Here’s the link to the USTA Senior International Page:https://www.usta.com/en/home/play/play-as-a-member/national/senior-international-competition-.html
Senior Team selections will be announced June 15th on the same page.
