When people talk about the approach, it is important to remember that both the process and the results will be impacted by the identity of the people taking the at bats. Last year, we had a number of hitters who really leaned into the three true outcomes. That approach increases the # of pitches per AB but also increases the # of Ks. This year, the Twins replaced a number of those players with hitters who have much lower strikeout rates. I suppose in a sense that is a change in philosophy, but if so, the change is at the front office, not by Rocco.
Also, when citing evidence, providing one (or two, or even ten) examples of a good or bad outcome isn't nearly as persuasive as citing a statistic that accounts for those examples and all of the other examples.
Personally, I think the Twins offense is much, much better this year. I think that's because (1) they have better players and (2) they are much healthier this year. I don't think Rocco is managing any differently this year.
