GENEVA (AP) Roger Federer and late replacement Marco Chiudinelli missed a chance to seal Switzerland's victory in a Davis Cup relegation playoff on Saturday, losing a five-set doubles match to the Netherlands.
Dutch pair Thiemo De Bakker and Matwe Middelkoop rallied from a set down to win 7–6 (7), 4–6, 4–6, 6–4, 6–1 after Federer's regular partner Stan Wawrinka scratched citing fatigue.
Switzerland leads 2–1 with second-ranked Federer due on court at Palexpo arena in the first of Sunday's reverse singles against No. 144 De Bakker.
If Federer loses, Wawrinka is scheduled to play 436th-ranked Jesse Huta Galung in a decisive fifth match.
The hard-court series decides which nation stays in the 16-team World Group next year.
