BRISBANE, Australia (AP) " Nick Kyrgios finished off John Isner with his 20th ace to give Australia a 2-0 lead over the United States in their Davis Cup quarterfinal on Friday. Kyrgios won 7-5, 7-6 (5), 7-6 (5) after Jordan Thompson upset Jack Sock 6-3, 3-6, 7-6 (4), 6-4 on a hard court at Pat Rafter Arena. In the second, Isner saved two break points at 5-5 and Kyrgios won the last three points. The 79th-ranked Thompson won both of his singles in his Davis Cup debut against the Czech Republic in February, but he was more impressive against No. The American rallied to win the second set, then recovered from 4-1 down to level the third set before Thompson won it in a tiebreaker.
