Arlington resident Mac Marsh had another strong showing by winning two races and being on two winning relays at another big recent and multi-team swimming and diving meet.
At the Washington Metro Championships in Maryland, the Gonzaga College High School senior won the boys 50 freestyle in 20.51 seconds, then was first in the 100 free in 44.69.
Marsh, who will swim in college at Cornell University, swam the third leg of Gonzaga’s winning medley relay (1:30.28) and the first leg of the first place 400 free relay (3:03.18).
His effort helped the Gonzaga boys finish second in the meet.
Marsh swims during the summer for the Arlington Knights of Columbus team, where he holds numerous team records.
