You seem to change your mechanics every time i come on this board.
Last Legion season, i did the same. I went game to game changing my mechanics to those that worked for major league pitchers… And while it was all fine and good (or so i thought), and seemed like it might help me, it ruined my pitching. I was so busy trying to become another pitcher (I tried Huston Street because of how he can hide the ball. Barry Zito because at the time i only had a good curveball, and a slow fastball, much like him. etc…). But i realized, with some advice from different people, that I was only hurting myself. Constantly changing things (especially when it comes to your rhythm, timing, and vision. Not just small things like getting the hips foward, which just takes repetition) was making it impossible for me to get any sort of consistency, which is something that is all too important in pitching. I believe Mr. Ellis has said somewhere on the site that the best mechanics are those that we are comfortable with and can be repeated easily; the same every time. So with all of that in mind, i decided to just be myself on the mound and do whats comfortable. The mechanics may not be perfect, but if you can repeat whats comfortable now, it will make altering slight problems in your mechanics (hips, shoulers…) that much easier and you can be much more successful.
So, I mean, if Lincecum’s Mechanics Truly feel better and comfortable to you, and really do make you that much better, then sure, why not use them. But dont try to replicate anothers mechanics just because they have success with them. Lincecum is always able to repeat his mechanics over and over because it is whats comfortable to him. Not everyone is the same. Instead of constantly changing your mechanics completely, why dont you try to focus your efforts into making the ones that fit you naturally work?
