I've said this before, but 90% of this thread has been said before, so I don't care repeating myself. There are plenty of guys now who strike out way too much, and don't seem to understand, or care, about situational hitting. I see it with Granderson, as a Mets fan. Adam Jones and Austin Jackson also come to mind. Don't change your swing or mindset with 2 strikes. There is such a thing as "trying to hit a ball hard the other way" as a righty when there's a man on 2nd and no outs. All of that is true, and I don't disagree part of the game is lacking that mindset a little bit now.
That said, some of the best hitters in the game strike out a lot, because they have the ability to swing very hard, and hit a baseball very hard. Having a guy as talented as Trout, or any elite hitter who strikes out 125+ times a year, choke up and focus solely on putting the ball in play with a man on third and less than 2 outs is doing a disservice to your team. There's a proper in between somewhere. But I don't disagree that there are too many players on the Adam Jones side than the Placido Polanco side. But if Trout focused on striking out no more than, 100 times, for example, I would guess he would have a much less productive year overall, as his slugging numbers would fall.
