Looking at the stats, Falla's had all the opportunities so far. He's had 5 bps but none in this set which is promising.
Arvind's serving let him down in set 1 from the looks of things. Unusually for him he hit no aces and served at only 44%. This meant Falla was able to exploit his 2nd serve and he did so, Arvind only winning 44% of 2nd serve points while Falla won 55%.
From the looks of things though, Arv has upped his game in set 2 67% 1st serves and 79% points won on 1st serve and 71% on 2nd serve.
