"We were up most of the game," said Cass coach Chris Allen, whose team scored two runs in the top of the first inning. "They didn't get a hit against us until the fourth inning ... can't ask for much more. (We) just couldn't close it out at the end."
Allen said his team played well defensively and got good pitching from Allison Story and Jessica Fetzer.
Story gave up two hits and one earned run in four innings, and Fetzer surrendered two earned runs and two hits in three innings.
"Even though it's a loss, if we play solid defense, typically, we keep ourselves in the game," Allen said. "There's nothing to be ashamed of."
After falling behind by two runs in the first inning, Sequoyah scored one run in both the fourth and fifth innings before the seventh-inning game-winner.
Lady Colonels' hitters Tuesday were Nicole Bailey, Story, Rachel Smith and Myra Russell, who each had one hit.
The Lady Chiefs secured their No. 1 sub-region seed last week, but Cass, which stood a chance to finish as high as No. 3, will instead head into Saturday's Region 7-AAAA tournament as the No. 4 seed from Region 7A-AAAA.
