The last man to face — and beat — Rafael Nadal in professional tennis, 80th-ranked Botic van de Zandschulp, gave the Netherlands a 1-0 lead over Germany in the Davis Cup semifinals Friday by hanging on to defeat Daniel Altmaier 6-4, 6-7 (12), 6-3 on his 10th match point. “At some point, I didn’t know what to do any more on the match points,” van de Zandschulp said.
