right Michael Conforto Jersey , or a left handed golfer hits it so it curves to the left. As any reasonably knowledgeable golfer will tell you, the slice is the result of "coming across" the ball with an "outside in" swing. As the club sweeps across the ball, the club strikes the ball in a slightly "open" position. This action puts sidespin on the ball and as it moves through the air it curves to the right (or left for a lefty).
Exactly the same thing happens in baseball when a right handed batter hits the ball down the right field line or a left handed batter hits it down the left field line. The ball curves away from the field towards the foul line. This slicing action also happens in other sports where a bat or racquet is used to strike a ball - sports such as tennis, ping pong, racquet ball, and cricket. And even in sports where simply throwing the "ball" with clockwise sidespin makes it curve to the right - think of bowling, lawn bowling and curling for example.
In many sports curving the ball like this is an important part of the game. Ping pong and tennis players, for instance Lucas Duda Jersey , want the ball to curve as it approaches their opponent and then bounce off the paddle or racquet at an odd angle making it more difficult for the opponent to control the return.
