Yes. I several videos of this technique being used at the MLB level. One in particular is Mark Reynolds fielding a ball deep off the right foot.
Like I said, I also just received a drill DVD from one of the best fielding DI schools in the country and they do not teach the field off the left, throw off the right technique.
It is taking me some time to adjust to my thinking, but I am starting to see the advantages. However, this technique can only probably be done by higher level infielders. I have a few kids that can do it and others that can't. For those who can't, it is the old field off left, throw off right technique.
