IFH% – This stands for infield hit percentage, which is the percentage of ground balls a player hits that end up being infield hits. It actually ties right into the fact I mentioned earlier about speedy players beating out grounders, and IFH% is the stat we use to measure that skill. Players with a GB% and IFH% that were both above-league average put up a .315 BABIP last year, as opposed to their counterparts, whose BABIP was just .300.
This new formula, which they referred to as gOBP, both credits the batter for reaching on errors and penalizes the batter for sacrifice bunts. They argue first, that any baserunner gives his team a chance to score, regardless how he reached base; second, that the batter can influence whether a batted ball becomes an error*; and third, that if HBPs (which are basically mistakes by the pitcher) are counted as positive events in OBP, then errors (mistakes by the fielders) should as well. To support these arguments, they show that team gOBP correlates better with runs per game (R/G) than the traditional team OBP.
Comparing a baseball or softball swing to a car engine is something that I do almost everyday. It’s an easy way to help kids and parents understand how the system inside the swing works. For someone who doesn’t look at hundreds of swings a day, it can be difficult to identify or help a player become a more efficient swinger of the bat. A lot of times coaches will see a result like a pop up or ground ball and associate the weak contact with lack of effort. Most of the time, this is simply not the case. In the following article I hope to help players understand the importance of not making “early mistakes” and also help coaches and parents break down the efficient swing. To do so, we will break the swing down into three phases.  The three phases are 1. Acceleration/Angle Creation, 2. Maintain, 3. Release. They are illustrated in the picture below in a Playoff home run by Francisco Lindor.
The third and final number in a slash line represents slugging percentage. This number is very similar to batting average, but instead of treating all hits as equals, it weighs each type of hit according to its significance. Slugging percentage (or SLG) is calculated by adding singles, 2 X doubles, 3 X triples, and 4 X home runs all divided by at bats. Another way of looking at it is total bases divided by at bats. Here is the official formula that is used:

"It's all about having a quality at bat," said Garrido, who has won five national titles. "You can't just go up there and start swinging and expect to get hit after hit. You have to be able to separate the pitches you can hit and the pitches you can't hit. And when you find that pitch let the ball location help you decide where you want to hit it. If you can do that you are on your way."
