Traverse City rallied from a three-run deficit, but in the end Southern Illinois prevailed Sunday with a 7-6 win in 10 innings.
The win finished off a weekend sweep for the Miners (49-28), who sit in second place in the West Division.
The Beach Bums fell to 40-38 with the loss and now are in third place in the East Division.
Southern Illinois took a 2-0 lead in the first inning off a Gordie Gronkowski home run. Traverse City tied the game with two runs in the fifth inning -- a Jeff Flagg solo homer and a Zack Pace RBI triple -- and then took a 3-2 lead in the sixth off a Chase Burch RBI double.
But the Miners came right back. Southern Illinois scored three runs in the bottom of the frame and made it 6-3 after seven.
The Beach Bums evened the score with a three-run eighth. Flagg had a two-run triple and then came home on a Greg Burns single.
With two outs in the bottom of the 10th inning, pinch-hitter Ken Gregory came up with an RBI single to score Boomer Blanchard for the win.
Scott Mueller took the loss in 2.2 innings of relief with two hits, four strikeouts and one earned run.
In Saturday's 10-1 loss to Southern Illinois, J.T. Hall tied the Traverse City season record with his 19th home run of the year. The Miners also won on Friday, 8-6.
Traverse City returns home on Tuesday for a three-game stand with Lake Erie. The Crushers are a half-game ahead of the Beach Bums in the division race. Then, the Beach Bums will hit the road for a weekend series at Joliet. The Slammers lead East Division by seven games and that will be their final series vs. Traverse City.
