It did improve. In 2017 Gio's velocity was way down, he was throwing about where he was right now.
In 2018, he was back up to the mid 90s but didn't have any control. In 2019 it had an increase and that mostly held in 2020-21. Gio's average FB was 94.2 in 2019, 94.0 in 2020 and 93.8 in 2021.
This year there has been a huge drop, averaging 92.9 so far.
