By Kees van Hemmen| Medium@ First, let's look at broad usage and efficacy trends. On the left we have 2023 pitch usage for Red Sox starters. On the right we have the same numbers for 2024. There's a lot of little stuff going on in here, but the main takeaway I have is this: the pitches that Red Sox starters have thrown most often this season are the same pitches they had the most success throwing last season. Notice that the 2023 chart is sorted by xwOBA against - basically, pitch efficacy.
