Thanks for the replies. I appreciate it, and I know you are trying to help. I seek honesty. Some of the thoughts you've shared have crossed my mind when he first told me he was working on the knuckleball. I also had reservations but I know he and his coach know what they are doing. Ultimately, it is their call to implement something they've practiced into a live game.
Truthfully, I think most of this is situational. He earned a weekend starting pitcher spot his freshmen year, and sophomore year. He was first team all-conference sophomore year, and was injured last year (junior year). His team won the conference his sophomore year, and he was a big part of it. He's 100% healthy now as a senior, and he had a great Fall season. He's not that interested in being drafted (he has pending job offer) so this will be his last college baseball year unless something really strange happens. His team is loaded with experienced pitching this year. We haven't discussed it face to face yet, but I suspect he is doing anything he can do to be effective on the mound and help his team win another championship. I've been watching college baseball pretty closely for the last 5-6 years. I have yet to see a knuckleball in competition, so that is why I'm asking this board this particular question. I have my reservations, but I trust his judgment 100%. He knows what he is doing mechanically, and mentally at all times. Pitching is a chess match to him, and the knuckleball could be another chess piece.
My biggest concern is the running game. He's very good at holding runners, and picking them off. He's been working with the presumed starting catcher, and he's got a good arm/pop time. I'm going to assume the knuckleball will be thrown occasionally, and the catcher has learned how to block it. His 4 normal pitches were pretty good in 2 of the last 3 years. So, I guess if he can mix it in as a setup or finishing pitch (throwing it for a strike) it may not be such a bad thing. But, I don't see him using the knuckleball as a primary pitch since his other pitches are pretty good.
Again, thanks for the thoughts.
