For example this Diyas vs Giorgi game
Giorgi won the first set 6-4, and then in the second set lost 6-1
(15:0, 30:0, 30:15, 30:30, 40:30BPSP, 40:40, A:40BPSP, 40:40, A:40BPSP, 40:40, A:40BPSP, 40:40, 40:A, 40:40, A:40BPSP, 40:40, 40:A) - the only game she won in the second set, serving.
So you'd think she lost it and Diyas had gotten the better of her, but then Giorgi wins the 3rd set 6-1 no problem. I've seen it happen before too, often with Jankovic. She'll win the first set easily, then it's almost like she's given up in the 2nd, and then she'll win end up winning the 3rd set 6-0 or something with ease.
I don't follow tennis much so I don't understand why this happens. Do players ever think (after getting off to a bad start in the 2nd set) "I've won the first set, it's OK if I lose this set and just make sure I win the 3rd"? And was it important for Giorgi to win that one game (making it 5-1 with Diyas to serve) so she would get to serve first in the 3rd set?
Just curious since tennis season has started
