Mattek-Sands and Sock beat Williams and Rajeev Ram 6-7 (3), 6-1, 10-7 tiebreak in an all-U.S. final Sunday.

It’s the second medal of the Rio Games for Sock, who won bronze in men’s doubles with Steve Johnson.

With the silver, Williams still tied the mark for most career tennis medals.

Mattek-Sands and Sock trailed 6-3 in the deciding super tiebreak then won six straight points.

Mattek-Sands thought they had won on their first match point, throwing her racket in celebration, but Sock’s return landed just long.
