Andre Agassi stumbled in his return to Davis Cup play, then Andy Roddick stepped up to square things for the Americans.
Croatia's Ivan Ljubicic beat Agassi in straight sets in yesterday's opening match in Carson, Calif. Roddick bounced back after a first-set loss to defeat Mario Ancic, 4-6, 6-2, 6-1, 6-4, in the second and final match of the day.
Ljubicic downed Agassi, 6-3, 7-6 (7-0), 6-3, in the match of Croatia's No. 1 player against the US team's No. 2.
The first round resumes today, with twins Mike and Bob Bryan scheduled to face Ljubicic and Ancic.
Playing for the Americans for the first time in five years, Agassi lost the opening set after falling behind, 3-0, then was up, 5-2, in the second before the hard-serving Ljubicic won three games in a row.
The loss was only the sixth in 36 Davis Cup matches for Agassi. In other first-round matches, Slovakia took a 2-0 lead against defending champion Spain in Bratislava. Spain is playing without three of its top players -- Carlos Moya, Juan Carlos Ferrero, and Tommy Robredo. In Moscow, Australian Open champion Marat Safin struggled past Adrian Garcia in four sets to pull Russia even with Chile, 1-1.
