Just as you felt, Manas ran out of gas after the long 3.5 hour match yesterday and a close first set today. He was down a break at 0-3 to start but out the break back and went toe-to-toe with Piccione for 3 sets till 5-5 in the first set when he even had a 30-40 BP... But from then on, he was out of it, as Piicione stepped on the gas. Manas won only 6 points out of the next 40 points. 57 06 loss.
That can happen to 16 year olds, especially on clay, when you grind for 4.5 hours within 24 hours. But another fruitful pro outing with 3 wins and a loss, and one more ATP point for the boy.
[R2] (Q) Manas Dhamne (IND,1342) l. (8) Andrea Picchione (ITA,477), 57 06
