Trenton swept a doubleheader from the Fisher Cats on Saturday night, and won both games on a walk-off bases loaded walk.
Wendell Rijo walked home Jhalan Jackson, who led off the seventh inning of the scheduled seven-inning game, to give the Thunder a 3-2 win over New Hampshire in the nightcap of an Eastern League doubleheader in Trenton, N.J.
In the opener, Bruce Caldwell's bases-loaded walk in the bottom of the ninth lifted Trenton to a 5-4 win.
The wins pulled Trenton (68-56) to within 1½ games of first-place New Hampshire in the Eastern Division.
New Hampshire took a 2-0 lead in the nightcap. Bo Bichette scored on a throwing error by Trenton second baseman Danienger Perez, and Connor Panas scored Harold Ramirez with an RBI single.
Caldwell tied the game with a two-run homer in the third.
New Hampshire outhit Trenton 8-2, and left eight runners on base in the loss.
Dusty Isaacs (3-3) took the loss as he pitched the fateful seventh, walking three and allowing the winning run. Starter Josh DeGraaf went four innings, allowing two runs on one hit. He struck out six and walked two.
Trenton starter Garrett Whitlock went 5 2/3 innings, allowing seven hits and two runs, one earned. He walked two and struck out four.
Trailing 2-1 in the top of the seventh inning of a scheduled seven-inning game in the opener, the Fisher Cats got even on Panas' RBI double, scoring Jon Berti.
New Hampshire (68-53) went ahead in the eighth as Bo Bichette singled home Santiago Espinal, who started the inning on second base, in accord with new minor-league rules on extra-inning play. But Trenton tied it up in the bottom of the inning on a Trey Amburgey sacrifice fly.
New Hampshire went ahead again in the top of the ninth on Espinal's RBI single to score Forrest Wall, but Fisher Cats reliever Corey Copping (0-1), who came in to nail down the save in the eighth, struggled. Gosuke Katoh started the inning on second. Jackson walked. With one out, Jorge Saez singled home Katoh. Jackson went to second. Copping then hit Jeff Hendrix to load the bases, and Trenton walked off with the win on Caldwell's four-pitch base on balls.
The game was scoreless until the fifth, when Berti homered in the top of the frame and Saez put Trenton on top with a two-run bomb in the bottom of the frame to make it 2-1.
New Hampshire starter Jon Harris went six effective innings, allowing two runs on six hits. Trenton starter Brian Keller went seven innings, allowing two runs on four hits, striking out four. Trevor Lane (1-1) got the win in relief.
