After stepping on second base, the fielder throws to first to complete a double play
In baseball, a double play (denoted on statistics sheets by DP) is the act of making two outs during the same continuous playing action.
The most common type of double play occurs with a runner on first base and a ground ball hit towards the middle of the diamond. A defender with the ball steps on second base before the runner from first arrives to force one out, and then throws the ball to the first baseman to force out the batter for the second out. Other types of double plays occur when fly balls are hit to the outfield and caught, but a runner on the basepaths strays too far away from his base. If the ball is thrown back to that base before the runner returns or tags up to go to the next base, the runner is out along with the batter for a double play.
The baseball statistics measures how often a player grounds into a double play in that situation.
A triple play involves three outs during the same continuous playing action.
The Giants are pleased to introduce the DoublePlay Ticket Window, a service designed to help season ticketholders resell their tickets to fans interested in purchasing choice seat locations at AT&T Park and Scottsdale Stadium.
All payments are made directly to the Giants and tickets purchased through the DoublePlay Ticket Window may be mailed to the buyer, at the Will Call Kiosks located at the ballpark, or may be picked up at will call.
DoublePlay is restricted to authorized users designated by the San Francisco Giants.
A slightly less common ground ball doubleplay is the 5-4-3 doubleplay, also called the "Around the Horn" doubleplay which occurs on a ground ball hit to the third baseman (5), who throws to the second baseman (4) at second base, who then throws to the first baseman (3).
Other types of doubleplays occur when a fly ball is hit to the outfield or a line drive is hit to the infield, and caught, but a runner on the basepaths strays too far away from his base.
Another rare situation is the unassisted doubleplay, which generally occurs when the second baseman or shortstop catches a soft, low line drive to retire the batter and steps on second base to put out the runner (by an obvious appeal) before he can tag up.
