The Richmond Flying Squirrels surrendered four late runs and fell to the Somerset Patriots, 5-4, in Sunday’s series finale at The Diamond.

The Flying Squirrels (8-19) split the six-game series with the Patriots (12-15) and saw their three-game win streak come to an end.

Richmond led 4-1 entering the seventh inning before Garrett Martin’s RBI double and Max Burt’s run-scoring single brought the Patriots within a run. In the eighth, Rafael Flores hit a two-run homer off reliever Dylan Cumming (0-2) to give Somerset its first lead since the first inning.

The Flying Squirrels loaded the bases with two outs in the bottom of the ninth, but Patriots reliever Cole Ayers (save, 1) entered and got Bryce Eldridge to fly out to end the game.

Somerset scored in the first inning on a Richmond error — the only run allowed by Squirrels starter John Michael Bertrand. The left-hander struck out five over 4.2 innings.

Richmond responded in the bottom half with an RBI single from Cal Mitchell to tie the score. Devin Mann followed with a go-ahead single to give the Squirrels a 2-1 lead.

Carter Howell added a solo homer in the second inning, his third of the series, to push the lead to 4-1.

Somerset’s bullpen shut down the Richmond offense the rest of the way. Will Brian, Kelly Austin (1-0), Heuston Morrill and Ayers combined for 5.1 scoreless innings.

The Flying Squirrels began a six-game road series against the Harrisburg Senators on Tuesday night. Richmond returns to The Diamond for a six-game homestand against the Erie SeaWolves from May 13 through 18.
