What’s Going On With Ian Anderson?
Ian Anderson was one of the better stories of the 2020 season. Entering the year as the No. 3 prospect in the Braves’ system and the No. 44 prospect in all of baseball, he was seen as a future mid-rotation starter who could help quickly. He did just that and more: Added to the rotation in late August, Anderson finished seventh in the NL Rookie of the Year voting despite making just six starts. He put up a 1.95 ERA in those outings, and while the supporting data said he wasn’t the Cy Young-level pitcher that number might suggest, he was still awfully good. He was even better in the postseason, allowing just two runs over 18 innings, striking out 24 and giving up just 11 hits.
Anderson maintained his rookie eligibility entering 2021 and earned the No. 2 ranking in Atlanta’s system (Eric Longenhagen and I discussed putting him at No. 1 ahead of Cristian Pache) and the No. 13 spot in this year’s Top 100 list. He looked like the cornerstone of a young Braves rotation that would help lead them to National League East title contention.
His first start of the year was vintage Anderson (or at least as vintage as you can get for a guy who is still a rookie), as he gave up one run over five innings and struck out seven. His next two were far from it: 11 hits and seven runs allowed over 10.1 innings. Game score is far from a perfect measure, but it’s a simple and quick look at a start, and Anderson’s game scores of 47 and 45 in his last two outings represent the two worst marks of his career. This could be a blip, or there could be some tough luck in there. But a closer look at the data shows that this is more than just a randomly-generated bad run.
When asked to evaluate a pitcher not living up to expectations, these are the first three questions I try to answer.
- Without knowing anything internally, is there anything to worry about in terms of health?
- Has the pitcher changed anything in terms of usage and location?
- Has the pitcher seen his pitch shapes change due to alterations in his mechanics or spin rate?
