I know Sumner is new. I was responding to the fact that Sumner had never made a state semifinal and that the only new Tampa school that had was Steinbrenner in 2019. I did not realize that Steinbrenner was 10 years old back then.
After checking, I see it had been open for exactly 10 years in 2019. When you get old, time certainly travels fast. So, the answer is that there is no recent Tampa school that has reached a semifinal in a four year window.
