Rafael Nadal

World number one Rafael Nadal will have to defeat young German star Alexander Zverev on Sunday to keep Spain in the Davis Cup after Germany took a shock 2-1 lead after a marathon doubles triumph. Tim Puetz and Jan-Lennard Struff stunned Marc Lopez and Feliciano Lopez 6-3, 6-4, 3-6, 6-7 (4/7), 7-5 as Spain were left to rue converting just two of 20 break points in a four-hour 40-minute encounter at the Plaza de Toros bullring. Nadal, 31, who marked his comeback on Friday after more than two months on the sidelines with a hip injury by seeing off Philipp Kohlscreiber in his opening singles match, now has to repeat his magic against Zverev, 11 years his junior. Nadal is on a record run of 23 successive wins in the Davis Cup, having not lost since 2005.
