The North Platte First Nationals swept a doubleheader against Twin Cities last night at Bill Wood Field. In the opener, North Platte shook off a first-inning deficit and erupted offensively, pounding out 17 hits in a 12-4 victory. The nightcap saw the First Nationals take a 4-2 lead into the seventh inning, but the visitors scored twice in the seventh to tie the score. North Platte had an answer, though, and walked off with a 5-4 win. The First Nationals improve to 15-11 on the season. They host Ogallala in a single game on Thursday night.
