Sevens are supposed to be lucky.

In a doubleheader of seven-inning games, the Beach Bums split with last-place Rockford.
TC won the nightcap 9-6 after dropping the opener 10-6.
The Beach Bums trail Lake Erie by a half game with four to go in the chase for the last Frontier League playoff spot.

Brown's sixth-inning infield single brought in Vargas for a 9-5 lead. J.T. Hall had hit a solo home run earlier in the frame.
Scott Mueller came on in the eighth and worked out of a bases-loaded jam by striking out Michael Hur to end the inning.
Traverse City started swinging right out of the games, scoring three runs in the first inning.
Chase Burch scored when Vargas reached base on a pitchers' error. Hall and Vargas came across on a single by Brown.
Brown drove in Hall again in the fourth inning.
GAME ONE: Bryan Banes didn't make it out of the first inning, giving up four hits and two walks while recording only one out to start off a 10-6 setback.
Banes was charged with all five runs the RiverHawks scored in the frame.
