The Panthers fell to the Rebels in a 7-6 final in a non-conference matchup with the co-Twin Lakes leaders.
Sioux Central rallied out of an early 3-0 hole. It was a 5-2 St. Mary's lead after three, but the Rebels knotted it up after the fourth and plated one in the sixth and one in the seventh to pull away.
Joe Sandhoff finished 1-for-3 at the plate with two runs scored and one driven in. Andy Drey was 1-for-3 and drove in one, as did Ryan Peters.
"For it being a non-conference game it was still quite a battle," said St. Mary's head coach Ryan Berg. "Each team fought hard and made some big plays. Unfortunately I made a bad judgment on a passed ball in the bottom of the 6th and sent a runner when I shouldn't have. It would have been the go ahead run, but instead we were thrown out at the plate. Had I played it safe, the next batter doubled and we would have scored. I am happy with how we competed, and though our win streak is snapped, I hope we will bounce right back and be ready to start a new one."
Bobby Rushton got the win for Sioux Central as he allowed four earned runs on six hits in seven innings. He walked six and struck out 10.
Mickenzie Nelson was 3-for-4 with three driven in to lead the Rebel bats. Brad Ripke was 1-for-4 with one driven in and one scored, Nick Wittmaack and Rushton were both 2-for-4, and Matt Schiltz scored three runs.
Sioux Central added a 5-4 win over East Sac Thursday, with Ripke going the distance and striking out six in the win. Colin Swanson, Tim Saunders, Nathan Leer and Schiltz drove in a run apiece as Sioux Central improved to 18-6.
Against fifth-ranked Garrigan, St. Mary's was held to just three hits, with one apiece coming from Tyler Munden, Sandhoff and Kennedy Drey.
Jacob Kottke took the loss, giving up two earned on nine hits in five innings. He walked three and struck out two.
"We simply made too many mistakes against a good team," said Berg. "We gave them extra outs and they capitalized. Our pitching was strong enough to keep us in the game, but the other two phases of offense and defense just weren't there for us."
The Panthers drop to 12-8 with the losses. They host Alta-Aurelia on Monday.
