The hosts of the ATP 250 event, the TNTA, say that they had just one singles' wildcard in their hand this time and the rest were decided by IMG, who are co-owners of the tournament.
At the biggest tennis event of the country, India's top singles players are expected to be in the singles main draw through wildcards if not by direct entry but this year only Ramkumar Ramanathan has been awarded the lucky entry.
While Saketh is ranked 170th, Somdev is a few rungs below at 177th in the ATP charts.
Yuki Bhambri was the only one who managed a direct entry due to his ranking of 93 in the ATP list but he pulled out after failing to recover from an elbow injury.
