Nadal warms up with a game of doubles

Just days after claiming his record seventh French Open title on the Parisian clay, Nadal warmed up for Wimbledon by partnering fellow Spaniard Marcel Granollers in a 5-7 6-2 10-8 win over Michal Mertinak and Viktor Troicki.

"The real thing for me is more preparation for the singles [match] tomorrow, to compete, to spend time on the court, to serve a bit, to adapt to the conditions on grass," Nadal told www.atp.com.

"That's probably going to help."

Nadal plays his opening singles match of the German tournament against world number 58 Lukas Lacko.
