Unfortunately, one other team I was helping did not advance, losing on the sets lost tie-breaker to a team they beat. The team I was helping, team A, went 1-1 in their first two matches, their loss being a heart breaking 3-2 loss where all the losses were in match tie-breaks, and they needed to beat the lone remaining 2-0 team in their sub-flight 4-1, or a 3-2 win with a little luck would do it too. Unfortunately, they won 3-2 but lost a set in two of the wins so they lost more sets and lost that tie-breaker.
This isn't the first time a team has won the head-to-head but lost this tie-breaker, but perhaps it will be the last? I'm was told that a USTA official said next year, head-to-head will be the first tie-breaker. Too bad it wasn't this year!
Good luck teams!
