Slugging percentage which is a component of OPS stabilizes at around a full season for a starting pitcher (550 AB). Odorizzi is at 247 at bats. It might be something teams look to at the season’s end to suggest there has been a change on skill level (or not) as they make a free agency decision about Odorizzi. At this point in the season the pitch level data is helpful and the Twins have much better data than we can see. I would guess that they also have some useful batted ball data. Of the traditional result data, strike out rate stabilizes earliest and it is encouraging that his strike out is up while his walk rate remains at career norms.
