Just for the record, RamK, then ranked 475, won the Q2 over Makoto Ochi (JPN,487) 64 62 to make the Nonthabri main draw, but unfortunately ran into a red-hot Valendtin Vacherot (MON,219) and lost 46 36 in R1... RamK has been in India since then, in the challenger circuit in February (results in this thread) and a couple of M25/M15 (results in this thread)... He won the Delhi M25 and was the runner-up at the Chandigarh M15.
So his rank is expected to go up from #410 now to inside top-350 in the ATP update after 2 weeks on April 1st.
He was in the entry list for qualies at the Barcelona challenger next week, but just withdrew. Not sure where he will be playing next. I suppose he may wait for the new ranking to come up on Monday and be useful for challenger qualies seeding from the next weekend onward.
