Assistant Major League Strength and Conditioning Coach
Hazael Wessin joined the Astros Major League staff as an assistant strength and conditioning coach in 2022. A native of Santo Domingo in the Dominican Republic, Wessin is believed to be Major League Baseball’s first full-time, Dominican-born strength and conditioning coach.
The 2023 season will be his ninth in the Astros organization, and his second at the Major League level. Prior to joining the Major League staff, Wessin served as strength coach for the Triple A Sugar Land Skeeters in 2021. In 2020, he was part of the staff assigned to the Astros alternate training site, which was a result of the 2020 minor league season being cancelled due to the pandemic.
In 2019, Wessin, who is fluent in Spanish, was the Astros Latin America strength and conditioning coordinator. Prior to that, he was the strength and conditioning coach for Class A Quad Cities in 2017 and Class A Advanced Buies Creek in 2018, with both of those clubs winning their respective titles.
Prior to joining the Astros, Wessin assisted the Boston Red Sox Dominican Summer League operations in 2014.
Wessin received his bachelor’s degree in sports management from Faulkner University in 2014. He also received his associate of arts degree in liberal arts from Western Oklahoma State College in 2012, where he played catcher on the baseball team. In 2011, his Western Oklahoma State squad captured the NJCAA National Championship.
Additionally, Wessin is a certified strength and conditioning specialist (CSCS).
