First off, Anything I type here is just my opinion, if you're looking for feedback on your swing or hitting mechanics , trust me you'll find it. But that isn't always a good thing. Let me explain, there are plenty of guys that will critique your swing and make adjustments but is success in hitting a baseball really about that? I'm more of an approach guy . I'm not suggesting that fundamental mechanics don't exist in a proper swing , What I AM suggesting is that based on your video, you have a fundamental swing already. So, if that exists why aren't you hitting? My 2 cents is going to lean towards questioning your approach . There are several different definitions to what an approach is. I'm gonna focus on one. Intent. And before I go any farther, understand this is an inside thing not a mechanical outer physical thing.
You can give Miguel Cabrera a broken down , beat up little league bat from Target, Manny Ramirez ( Back when he was Manny ) a girls softball bat or a damn piece of a tree trunk and throw a baseball at them in a cage and they're going rip the ball. You could ask Cabrera to put his legs close together and do a leg kick and he'll still rip the ball or ask Manny to crouch down like a little guy and he'll still flat out mash. Why is that?
Those guys are extremely talented, we all know that, but consider this: Those guys are more Approach based than mechanics based. Their approach really is just sort of basic 'See the ball......hit the ball' But it's rooted in reliance on hand eye coordination and absolute confidence that they will. That's the thing, These guys don't doubt their abilities! I'm not suggesting those guys don't work on things or make adjustments , what I'm saying is that is NOT the driving force in what they do. Those guys have an intent or a mental approach that probably makes up 80% of it.
Most of the time when a guy starts looking for mechanical answers he's lost all confidence in his swing. And that's the real problem.
What's the old saying? 'A man wakes up w/10 problems a day. Once he ' thinks' he has a problem.....he has 11
Yogi Berra said it best, 'You can't hit and think at the same time' . I believe that.
Joc Pederson is a very talented young ballplayer that plays for the Los Angeles Dodgers. He made the All-Star team last year. He fell into a slump in the 2nd half of the '15 season. Then it got worse. Now keep in mind Joc is surrounded by the best hitting instructors in the country, they worked w/ him...It got worse. Think about that. The BEST teachers available and it got WORSE. They've tweeked this guy to the point that I'm not sure if he'll stay in the big leagues . (In my opinion, they should leave him alone and let him find his swing...The swing that got him to the Bigs)
My advice is that you don't change anything as far as your mechanics . As a matter of fact I woudn't even swing a bat for a few days, and then the next time you go to hit in a cage or someone throws you BP , No practice swings. Just step in the box. Put the bat on your shoulder and let it rest there ( Paul Goldschmidt ) fingers/Grip real loose and stay like that till you load.Then just let it fly and only focus on seeing the ball. Don't think about your hands or any mechanics......Just swing with intent .
Have you ever seen a 'bad ball' hitter? It's all intent. Or a one handed double? Same thing intent. The guy decided he was going to hit the next pitch. Period.
Lastly , as you can see, I believe hitting mechanics are overrated. They're important but hugely over valued in guys that have been playing the game for a while. Confidence and seeing the ball well will get you farther in my opinion. When you have a moment go to youtube and watch Derek Jeter swing then while your there, look up Derek Jeter in High School. When you see his swing its pretty much the same swing he's always had. That speaks volumes regarding mechanics and changing guys.
