Nadal to Play New Stuttgart Grass Event
BERLIN — World number five Rafael Nadal will begin his grasscourt campaign at the Mercedes Cup in Stuttgart after the event switched surfaces to green turf for the first time this year.
The June 6-14 tournament replaces the former red clay event that ran until 2014 and will be staged the week after the French Open.
"Last time I played there it was a different event, on clay. This time it will be on grass court and I’m really looking forward to return to Stuttgart,” Nadal said in a statement.
With the introduction of a three-week interval between Roland Garros and Wimbledon, Germany will host two men's grasscourt events from this year.
