Some low-scoring contests are played in less than two hours. Other games last four hours or more if the score remains tied and go into extra innings. And that's fine. Players are allowed to ask for numerous time outs to adjust all manner of hats, helmets, and batting gloves. Players can leave their positions to talk to each other, to yell at umpires, to fetch a pair of sunglasses, to replace a broken bat.
Pitchers can take time to shake off a signal.
Coaches can stop a game to chat with the pitcher or hitter. In this way, baseball is a little bit like life itself. Sometimes you have to pause and examine where you are. There is no shot clock as there is in basketball, no 30-second deadline to run a play as there is in football. There are no quarters or halves.
