Move to 5:42 , at the score 11-11 , Why Sanchez need to return a shot that was landed way outside the baseline as she was standing. If you say there is no OUT call from line judge , why Sanchez just dont ask for hawk eye instead of stupidly returning a ball that landed some 2 metres from baseline ? After Sanchez return it to Zhang , the ball is still in the air when Zhang return it, but how come line judge call it OUT when the ball is not landed yet ? It landed 2 metres from baseline in Sanchez place , but no OUT call .. At the other end it ,the ball still in air and have never landed but judge call OUT ? Any Tennis Expert here can explain this ?
