My 2022 ended the summer season in late July regularly hitting 83. In August he shut down throwing and started working out hard on a program through Cressey Sports Performance. He started throwing again in mid October touching 85 and touched 87 in early December. He put on roughly 13lbs of muscle and increased both flexibility and stability in key areas between early August and late October. Hopefully that is a data point you can use but I am not certain a sample size of one really means anything.
