on the same base. The offensive team scores a run when a runner returns safely to the home base after advancing through all three field bases. If a batter advances to the third base on their batted ball, it is a "home run". He can then stay on the third base and try to score again as a regular runner by reaching the home base on a later play. Differences from baseball The most significant differences from baseball are: The first bounce of the ball is decisive: It must bounce within the play area, and may then roll over a line and still be in play. The back line on the fly counts as a laiton (literally "illegal", a foul ball). The foul lines are also on the sides and the front of the field. So if a player aims high and hits a very hard hit that would be a certain home run in baseball, it is counted as a foul in pesäpallo. This increases the tactical approach. All home runs, therefore, are the "inside-the-park" variety. Catching a ball in flight is not an out, but forces all runners advancing at the moment of the catch to attempt to reach the next base. If they succeed they must return to home base with no further consequences (this is called a haava, literally "a wound" or simply koppi, "a catch"). If they fail to reach the next base, they are out. Instead of a "batter's box", the home plate serves as a pitching plate, which is round with a diameter of . All other batting team players stand in a semicircle near the batter. Players generally have little difficulty hitting the ball, so the main target is not just hitting the ball but selecting a suitable type of hit and directing it correctly. There are many different types of hits used, here are a few examples: Snap (short) hit: Normally used for advancing fast runners between bases, aimed to avoid defensive players. Usually hit in such way that the ball takes a hard spin. Fly hit: An intentional high hit to be caught, often used to give way for faster runners. High drive: Aimed to drop to the field between midfield and outfield, with a top spin. Excellent for scoring. Bouncer: Used for advancing fast runners, hit downwards very hard to be bounced right next to the front arc. Aimed
