How do you feel about swinging inside out, back through the middle, with a 90' contact angle with less than two strikes?
I found that Epstein's material basically teaches the 90 degree contact swing on all swings. I credit Epstein's material for my DD's tight hand path. Every girl that I've worked with that has done lots of swings from Epstein's "Torque" drill, has a tight hand path and can hit the inside pitch. Three of the girls I've worked with played on our HS team this past season. You can pick out these girls from the rest of the team based on their hand path. They all have tight hand paths and can hit the inside pitch really well. During a HS game last season, one of the girls who did a lot of "Torque" drill swings gets an inside pitch. She turns on it and hits a shot to left field. One of the parents blurts out, "wow, she really pulled her hands in on that one". Of course the batter really didn't pull in her hands. She starts with a tight hand path and adjusts from there. As slaught says; you want to prepare to hit the pitch up and in; which requires the tightest hand path of any pitch location; and you naturally release the angles in your elbows and wrist on pitches away.
With less than two strikes Williams' philosophy was to try for the pulled line drive in advantageous counts. His feeling was that a pulled line drive 380 feet was a HR in most ball parks. I'm a hitting nut, so I work on some of this stuff with my DD. Sometimes in the cages, I will give her a count and have her adjust her approach based on the count. She tries for a pulled line drive if I give her a count like 2-0 or 3-1, and she tries to inside out the ball if I give her a 0-2 or 1-2 type count. The pulled line drive is kind of the opposite of the inside out swing, because with the pulled line drive you are trying to get the arms a little more extended at contact. I'm not sure if shooting for a pulled line drive applies in FP because it seems like a lot of the fields we play on are the same distance to all fields. Not sure about the college fields. I do think in my DD's case, giving her the thought of going for a pulled line drive in counts where the pitcher has to come in with it, helps her to really tee off with her swing. She's gets a little more aggressive, which is kind of the point when you get ahead in the count.
It seems like every one of the better college teams has a pitcher that can throw 68-70 miles per hour, so a tight inside out swing on every swing might be the way to go. Ted mentions shortening up a little and trying to be quicker against really fast pitchers. He used a vertical bat handset, but once in a while if he were facing a really fast pitcher, he would flatten the barrel out a little in his stance and think about getting more on top of the ball. Getting more on top of the ball is another way of saying keep a tight hand path.
I've never hit against a pitcher throwing 70mph from 45 feet, so I try and teach my DD the basic concepts that Ted talks about in "TSOH", and then leave it up to her to decide what she wants to do with the information. I've found that a lot of the girls are smarter than we sometimes give them credit for. When I'm coaching during a game, I over hear some of the girls saying stuff that clearly indicates they are thinking and making adjustments from one at bat to the next; and the better ones will make adjustments in the middle of an at bat.
