ATP: Wawrinka, Rublev and Co. visit Doha

While the new tennis year is already in full swing in Australia, the first regular ATP 250 tour event takes place this week in Doha. Even if the 28th edition of the Qatar ExxonMobil Open does not feature any of the big four in men's tennis or a top 10 player compared to previous years, the 28-man field is well balanced.
