Nobody will try this IMO unless forced to it. Cash has been forced to it and has done a great job with it IMO.
I don't like using a serious late innings arm in the first inning unless at home and trying to keep your anemic hitting team from having to take their first AB's already down in the game, possibly enough to rob them of some of the tools an anemic hitting team would use to try to generate some runs. So other than that, it's fine in a pinch. It does help that regardless of all the news about pitchers throwing 98, I think what is more interesting is the number of pitchers throwing an assortment of hooks and changes. The Curve is back in a big way for one thing.
The other component of relief pitching that your pitchers better feature if you are going to do something like what Cash has done is they need to have resilient arms. Additionally, the times you run a starter out there, he better not collapse early as that could throw off your plans for a week.
