Billy Kozak and Joe Matzel had 14 and 12 points, respectively, for Sidney, which is the last unbeaten in the MAC.
Kozak had eight points in the first half as the Warriors opened a 32-24 lead at halftime.
“They went on a little bit of a run just before halftime,” Unatego coach Jim Knight said. “I still thought we were OK at that point. We needed a big third quarter. We needed to get stops and we just didn’t. Hat’s off to Sidney. They’re a good team and they played well.”
Matzel scored eight points in the third quarter, when Sidney outscored the Spartans, 17-11.
Brandon Walters, Hunter Sowersby and Damian Zimmer scored eight points apiece for Sidney.
Tyler Butler had 13 points and 12 rebounds, and Quinn Barnhart contributed 16 points for Unatego (6-4, 5-1), which will travel to Deposit on Tuesday.
Walton 59, Delhi 52, OT
Dalton Kaminsky scored a game-high 24 points to lead visiting Walton to a Midstate Athletic Conference victory in overtime.
“They’re on a roll right now,” Delhi coach Warren Kelly said of the Warriors, who made 10 three-pointers for their third straight victory. “They’ve made 28 threes in the last three games and they’ve won all three. It revolves around Kaminsky.”
Kaminsky, who missed the early part of the season because of a football injury, was absent when Delhi beat Walton, 62-45, on Dec. 11.
“He didn’t play the first time and we won by 17 points,” Kelly said, adding that he didn’t have rebounding statistics for Kaminsky but he was sure the Walton quarterback finished with a double-double. “He facilitates so much for them and tonight, he did that again.”
Eric Zimmerman and Colin Adam contributed 13 points apiece for the Warriors, who won with an 11-4 run in overtime. Zimmerman, Adam and Kaminsky hit three three-pointers apiece for Walton, which got another one from Trevor Zandt (nine points).
