Andrew Miller bounced back in 2020 after a difficult 2019 season which saw him allow a career high home run rate (1.81 HR/9) while also experiencing a drop of more than half a mile per hour from the previous season. However, Miller’s strong 2020 season (2.58 FIP, 3.20 K/BB) came with some serious red flags that make it unlikely that Miller will repeat his success in 2021.
To begin with, the St. Louis Cardinals’ reliever threw just 13 innings, thus giving him too small of a sample size to trust his results, especially after a 2019 season in which he was worth -0.
