At the Miami Open (2018), Bethanie Mattek-Sands came back from a first set loss and a 5-2 deficit in the second set to tie up the set 5-5. From our grandstand seats beside her court, I could relate to her feelings, when she turned around and gave herself a “you can do it” fist pump.
Watching world class tennis players alongside the court gives the enthusiastic amateur like myself a great demonstration of how tennis is played at the highest level. Just look at Rebecca Peterson of Sweden serve the ball. She is powerful!
