PORTLAND, Ore. (AP) " Jack Sock needed a little time to get up to speed Friday in his first Davis Cup match. The U.S. last hosted a Davis Cup match in 2014, when it lost in the first round to Britain in San Diego. Should the United States clinch the Davis Cup tie Saturday, Sunday's reverse singles matches will be shortened to best-of-three sets. The United States is 157-3 when leading 2-0 in Davis Cup competition. Croatia claimed its only Davis Cup title in 2005.
