On Friday, the junior won the Maryland Interscholastic Athletic Association A Conference individual tennis title, beating McDonogh's Jake Gober, 6-3, 6-1. That performance came after Portner won at No.1 singles and No.1 doubles in leading the Gaels to their first team tennis championship since 1984, when they played in the Maryland Scholastic Association. Portner is a lefty who hits a heavy ball with lots of topspin, and he's smart on and off the court. He carries a 4.0 GPA and is in contact with Ivy League schools. In the USTA rankings, he is in the Top 5 in the Mid-Atlantic area and No. 60 nationally for his age group.
