FRANKFURT, Germany -- Philipp Kohlschreiber and Florian Mayer won their singles matches on Friday to give Germany a commanding 2-0 lead over Spain in the first round of the Davis Cup World Group.

Kohlschreiber had little difficulty in defeating Roberto Bautista Agut 6-2, 6-4, 6-2 in 1 hour, 43 minutes.

Kohlschreiber, the world No. 27, attacked from the start and won five games in a row to take the opening set in 26 minutes. Bautista Agut, who was making his Davis Cup debut, failed to earn a single break point.

Mayer had it much tougher later against Spanish No. 1 Feliciano Lopez, who fought back from two sets down and saved four match points. The German eventually prevailed 7-6(6), 7-6(4), 1-6, 5-7 6-3 in 3 hours, 51 minutes.

The result left five-time champion Spain on the brink of its second successive first-round Davis Cup exit after losing to Canada last year.

Germany needed one more win in the five-match series to complete its first victory over Spain since 1994.

The winner will play France or Australia in the quarterfinals in April.
