District 1 claimed three of the four available titles as Unionville's Michael Furr won the Class AAA singles trophy, and Radnor's Andrew Zhong and Gavin Studner won in Class AAA doubles.
Blumenthal's twin sister, Marni, was part of the state doubles championship team in the fall.
"Max had to win to keep up with the family tradition," Rams coach Jack Ladden said. "Marni has three gold medals and this is Max's first so he was really happy.
"Max and Sam have been doubles partners for three years now. They were dominant in the tournament, overpowering everybody. They both are tremendous at the net and each has a great serve."
Furr won his showdown with Conestoga's Kevin Wang, 6-4, 6-4, and avenged the 6-3, 7-5 loss he suffered against Wang in the District 1 final. Both players are juniors.
