Congrats to Jacob Bosiokovic on signing with the Minnesota Twins! ✍️ Jacob Bosiokovic came to Tread this fall, where a mocap analysis revealed some mechanical inefficiencies that he and matt marsili were able to attack. Less than 4 months later, he was back up to the upper 90s & signed. 📈

Congratulations to Conlan Taylor as he signs today to continue playing baseball at the Division 1 level at Binghamton University. OA Schools


Athlete update: Gordon Graceffo came into the off-season after an inconsistent 2024 campaign. Velo fluctuations, command fluctuations etc. We honed in on two reason we believed this was probably happening. Inconsistent first move or drift through leg lift, and arm path.

I have to say all of this could not have been done without the help of matt marsili working with me as co-coach and contributing massively. Two heads are better than one and I think this upcoming season for Gordon will be a truly great one. Tread Athletics

When Jacob Bosiokovic came to Tread, he was a recently released 31-year-old outfielder turned pitcher. He took part in Tread's free mocap assessment for professional pitchers in the fall and we identified a few mechanical deficiencies. Bosiokovic worked with matt marsili for 4 months
