A bat and a ball are used in the sport of baseball
Baseball is my favorite sport. I actually coach high school baseball. Who is your favorite team?
usually two tea ms take turns trying to hit a ball with the bat 
That's correct. Once a team collects three "outs" then they switch who hits
it is true tht only the ninth inning declares the end of the game and there is no game clock
While that is true they could go into "extra Innings" because the game cannot end in a tie.
. The objective of the defensive team (fielding team) is to prevent batters from becoming runners, and to prevent runners' advance around the bases. A run is scored when a runner legally advances around the bases in order and touches home plate (the place where the player started as a batter). The team that scores the most runs by the end of the game is the winner.
The first objective of the batting team is to have a player reach first base safely. A player on the batting team
Baseball
Baseball is a bat-and-ball game played between two opposing teams who take turns batting and fielding. The game proceeds when a player on the fielding team, called the pitcher, throws a ball which a player on the batting team tries to hit with a bat. The objectives of the offensive team (batting team) are to hit the ball into the field of play, and to run the bases—having its runners advance counter-clockwise around four bases to score what are called "runs"
