Ball speed world record

A day ago, 19 April, 2011, new world record for the fastest ball was officially saved. The hero is Aroldis Chapman. He is from Cuba and threw fastball with speed of 106 miles/hour.

You can watch on this video. It is the second pitch and will make you shocked.

Designated Hitter

Designated hitter is hitter that only participates in hitting, but doesn't play on defense. In batting order, 8 out of 9 are fielders. Last one to fill in can be either pitcher or designated hitter. It depends on countries' baseball rules. In National League of Major League, pitcher bats. However, in American League of MLB, designated hitter joins the batting order instead of pitcher. Usually pitchers are 8th batter because 8th position is for hitter who is worst on making hits. However, designated hitters are mostly 4th hitter, which is for the hitter with the most power.

Triple Play

Triple play is when 3 outs are made in once. It rarely happens because making 3 outs take a lot of time compared to double play, so there is more possibility that the last runner might be safe before the ball reaches any base to make third out.

This might help you to understand better.

Stealing Base

Did you see runner on bases suddenly starting to run to next bases? It is because they were trying to steal bases. Runner can start to run to steal base as pitcher starts wind-up. (Wide-up is action that pitchers do before throwing pitch.) If the runner touches the base before the fielders tag him, he is safe on stolen base. The special type of stealing base is home-steal. It is exactly same as other stealing bases, but what makes it unique is that the stolen base would be the home base. It rarely happens because catchers usually have ball and it has lots of probability of getting out. Since the distance between home plane and second base is the longest, stealing second base has the most chance of succeeding stealing. Usually, only fast runners try to steal, but sometimes runners with normal speed also steal bases for operation. For example, to increase chance of surviving, two runners steal bases at same time. It is called double-steal. Stealing base is inevitable in the match. However, you need be aware of that you should stop stealing bases when leading the score by great number, such as 10 points or more than opponent's runs, because it is manner that you should follow.
