DOHA, Qatar, Jan. 3 (UPI) -- Top seeds Rafael Nadal and Roger Federer collected first-round wins Tuesday at the Qatar Exxon Mobil Open tennis tournament.
While both advanced, they did it in very different ways. Nadal battled Philipp Kohlschreiber for more than 2 1/2 hours in a 6-4, 6-7 (2-7), 6-3 win. Nadal, No. 2 in the world and seeded No. 1 in Doha, lost his serve twice but still managed to run his career record to 8-0 versus Kohlschreiber.
