That early success hinted at a doubles specialty that would later define his professional career.
Growing up in Florida’s competitive tennis environment helped shape Winegar’s game. He combined his junior development with strong academic priorities, eventually choosing a college pathway to continue both pursuits. The blend of Florida training roots and a disciplined academic focus prepared him for the next step in his tennis journey.

At Columbia, he was twice named First Team All-Ivy and earned NCAA All-American honors while partnering with Michael Zheng and Max Westphal, reaching the Elite 8 at the ITA Fall Nationals with Westphal during his sophomore year. He was ranked in the ITA National Top 10 twice and finished his senior season ranked No. 1 in the ITA Northeast Region and No. 24 in the ITA doubles with Zheng, graduating with a bachelor’s degree in psychology.
After Columbia, Winegar completed a postgraduate year at Duke University, playing for the Duke Blue Devils. Partnering with Cooper Williams, the pair finished as Top Ten ITA All-Americans. Together they won the inaugural American Collegiate Wildcard Playoff in Orlando, Florida, earning a spot in the main doubles draw of the 2025 US Open. That victory served as the springboard for his transition to the professional circuit.
