Philipp Kohlschreiber routed Roberto Bautista Agut 6-2, 6-4, 6-2 in Friday's first singles match to give Germany a 1-0 lead over short-handed Spain in first-round Davis Cup action.
The 27th-ranked German needed just one hour and 43 minutes to brush aside the 52nd-ranked Spaniard, who was making his Davis Cup debut.
Kohlschreiber, who was more comfortable than his opponent on the fast hard-court surface at the Fraport Arena in Frankfurt, did not face a single break point throughout the contest.
Bautista Agut was more competitive in the second set but Kohlschreiber was able to snag one break of serve to take a commanding lead in the match.
In the third set, the Spaniard's level dropped and he seemed discouraged by the large deficit.
The visitors now face an uphill climb in new Spanish captain Carlos Moya's debut, needing to rally and win three of the next four matches without the services of world No. 1 Rafael Nadal or world No. 5 David Ferrer.
In Friday's second singles match, Spanish world No. 26 Feliciano Lopez is taking on German world No. 29 Florian Mayer. EFE
