I recently noticed during my Indian Wells trip (had some good courtside seats ) that most of the pros tend to have an extreme continental grip for the serve. More like an eastern backhand grip. I watched Raonic, Anderson, Federer, Murray and others. I was sitting diagonally from the court so had a nice view of the serving motion. I might be wrong, so wanted to verify with others who have watched pros serving. I have a continental grip for serving, but have been experimenting with the eastern backhand grip. It still does not come natural to me, but when I get it right the serving swing motion seems to be faster through the air and also it seems to work great for wide serves on the deuce side. Does anyone here serve with such a grip and know what advantages it might have?
