These six drills are designed to generate more power for hitters across the games of softball and baseball. Working on a good path to the ball and through the zone is immediately one of the most important factors in driving the ball. Once that is worked, then can work on several drills to improve hip and lower half rotation, then work into weight transfer from the back leg through the zone, and put it all together with the crossover drill. For more drills to improve power for softball hitters, check out the hitting drills in The Hitting Vault.
How do these players create such a powerful swing? Rule number one; do not confuse POWER with strength. These are two very different dynamics. Power is an explosive movement. It is created through a combination of speed, and strength. Strength is created through maximal force. This is the biggest learning lesson here; you do not create power for hitting by lifting maximum weight. Power lifting like bodybuilders and muscle heads do, does not translate into softball power hitting. Power lifting is mostly all for show and not athletic performance. If you have the biggest arms, traps, and chest in the world, how are you going to swing the bat? Power lifting and Power hitting are two totally different things.
Many players make the mistake of losing the momentum of their swing as soon as they make contact with the ball. This is a mistake. You want to add as much power and momentum as possible to the ball to throw it far. In order to do so, you should continue swinging your bat even after it has hit the ball. A good way of doing this is to assume that you have to hit two other balls immediately behind the ball you are hitting. So you have to continue swinging through the entire motion before stopping. Continued swinging adds extra power to your hit, essentially adding a ‘pushing’ momentum to it apart from the hitting force that you put into it.
Equal power and equal run scoring abilities, yet using batting average, Dozier is inferior.  It doesn’t seem fair that two players of equal skills are ranked so far apart in fantasy, but player X had 31 more hits while Dozier had 31 more walks with the same results.  If you’re a numbers guy you might have guess who player X is, but for those that haven’t figured it out, it’s Anthony Rendon.  Rendon is shooting up draft boards while Dozier is left waiting until the mid-early rounds.  If there was a poster boy for using OBP over BA, it’s Dozier.

On base plus Slugging (OPS): Somewhere, half way between traditional statistics and sabermetrics is what Fox sportscaster Joe Buck called "that new OPS statistic." Yes, he actually said that, during the 2011 World Series broadcast. (Notice that I resist the strong temptation to go off on a rant tangent, here, in an effort to stay on topic.) On base plus slugging, or OPS, is just that. Take a player’s on base percentage and add his slugging percentage, and voila, you get OPS. Now, I think that OPS is a very useful statistic ... for sluggers. But it’s still very much a slugger’s stat. OPS gives one base for walks, two for a single, three for a double, four for a triple, and five for a home run. We’re used to seeing OPS being discussed in conversations now when discussing the MVP awards for each league and it's commonly used in baseball discussions these days.

I like to hit off of a tee into a target at least 45 feet away. This will allow you to see the flight of the ball and know if you are striking it consistently the same way or if you are all over the place. With front toss, you should be able to hit every ball on the same trajectory. Players that come work with me for the 1st time usually hit about half of the balls within 20 feet of the plate usually slightly to the pull side (a rollover).
There is a very important Biomechanical Principle that pertains to the initiation of the baseball swing. The principle states: "A ballistic motion, once initiated, produces trajectories that can only be changed at its margins." This means, the forces applied to the bat during initiation produce trajectories that will set the tone for the entire swing. If the swing is not initiated correctly - little can be done to compensate for it.
BAA is very common in evaluating pitchers -- especially when assessing opponent handed-ness splits. A pitcher cannot have an ERA against left-handed hitters because they are interspersed with righties in lineups. So when a pitcher's ability against hitters from each side of the plate is being compared, it is usually done by using either BAA or OPS-against.
