My son and I were having the conversation about Keith and wondered if at this point in his career, he's someone who needs to have 1 position and focus on it. He became an average 2b by the end of last season. Then he spends the offseason working on playing a new position, learning new footwork, stretching, new reads, when to try and field the ball, and when he needs to get to first, etc. So almost all his mental prep is for that. Then all of a sudden, he's back to 2nd when he still hasn't gotten the position he was working on all off season down. For some players, no problem, they are back "home" to a position they are comfortable with. Keith may not be there yet. It doesn't mean a year or 2 down the road, he couldn't be effective at multiple positions, but in the very small sample size of approximately a week-10 days, he definitely doesn't look like he is.
I too think the best for the team overall would be to go back to Keith at 2nd, Tork at 1b, and hopefully Torres is willing to go to 3rd (assuming what he said the reason for refusing to do it in NY is accurate). Then Keith can focus again on 2nd and hopefully get back quickly to where he ended the year last year.
