@joel_myers_tennis: Slice wide Many players hit their wide serves too hard and as a result don’t get enough side spin on the ball to work it away from the returner. Note: a slower serve doesn’t mean a slower swing. Both players have HIGH swing speed to generate this amount of work on the ball Ace speeds Carlos : 106mph / 171kph Novak: 111mph / 180kph Video Credit: @functionaltennis #joelmyerstennis #tennis #tennistips
