The Flying Squirrels (42-41, 9-5), the Double-A affiliate of the San Francisco Giants, snapped their four-game losing streak, evening the series against the Senators (37-45, 6-8), the Double-A affiliate of the Washington Nationals.
Seymour (1-2, 3.91 ERA), a sixth-round draft pick in 2021, allowed one run, a solo homer by James Wood, the top prospect in the Nats farm system, in the top of the second inning, over a season-high five innings with six strikeouts.
Richmond trailed, 2-1, entering the third inning. Against reliever Odalvi Javier, Wade Meckler tied the game with an RBI single.
Later in the frame, Vaun Brown brought Meckler home from first with a double to give the Flying Squirrels a 2-1 lead.
Wil Jenson took over in the sixth and threw two scoreless innings, stranding our baserunners. Raymond Burgos fired a scoreless eighth inning.
In the ninth, J.T. Arruda hit a two-out triple to put the potential tying run at third for the Senators, but Juan Sanchez (Save, 2) worked a groundout from pinch-hitter Donovan Casey to end the game.
