Tennis great Rafael Nadal hopes to return to competitive action at the upcoming ATP tournament in Doha. The 37-year-old Spaniard is on the entry list for the Qatar ExxonMobil Open from February 19 to 24, organizers said. The 22-time Grand Slam winner, who has been struggling with hip issues, played for the first time in nearly a year in the Brisbane International at the beginning of January. However, he suffered a muscle injury in his quarter-final defeat to Australian Jordan Thompson and pulled out of the Australian Open.
