if there wasn't an umpire than there would be no way to tell if the batter got a strike or not. only the umpire can decide that."The men in blue calling the balls, strikes and outs on the bases don’t have smartphones at hand like the rest of us watching the game from the stands or on TV. They receive scouting reports before each series on who and what to watch for. For years before becoming a viral YouTube sensation for an ejection in 2007 in which he crawled on his stomach and launched a rosin bag like a grenade, Wellman, the manager of the San Antonio Missions, has been near the top of those reports with a reminder that his temper can be volcanic, even theatrical." As you can see there are many different things that an umpire does.
a short stop is a fielder positioned in the infield between second and third base, or the position itself. "The best shortstops play smart. They know how to get the most out of their natural abilities, how to properly execute routine and non-routine defensive plays, how to be a team player, how to protect themselves from injury, and other things to give them an edge. A shortstop also needs to know when, what and how to communicate with the other infielders."
fast pitches is one of the most common pitches in the baseball game. "Currently, Aroldis Chapman holds the record for the fastest recorded pitch in the history of major league baseball at a speed of 105.1 mph. Aug 28, 2016" As you can see fast pitches can be very effective and are a good way to strike somebody out.
pitching is one of the most important roles in baseball. you can't play baseball without a pitcher. there are different kinds of pitches for example a fast ball, curveball, screw ball and many more.
