Science Hill (25-11) claimed its second straight District 1 title and its fourth in the last five years with a 5-1 decision over the Vikings.
The game, which began at 6 o'clock, did not finish until after 10:30 following a two-hour and 10-minute rain delay with SHHS leading 1-0 in the second inning.
Both teams now move on to Region 1-AAA play on Monday, when Science Hill hosts Jefferson County and Tennessee High (25-11) travels to Sevier County.
The Hilltoppers played Baseball 101 with Caleb Marmo and No.3 hitter Matthew Levi to gain a 2-0 lead through three innings.
The speedy Marmo scored both early runs, opening the bottom of the first and third innings by working THS pitcher Zach Anderson for walks. Then, after managing his way into scoring position, the Hilltopper leadoff man was able to trot home on a pair of RBI singles from the hard-hitting Levi.
Levi finished with three of Science Hill's seven base hits.
Another key ingredient to the Science Hill win was doing two-out damage offensively, like when it scored twice in the fourth after opening the inning with a strikeout and a pop out.
Following a two-out single by Ben Edwards, Jack Torbett ripped an RBI double down the left-field line to make it a 3-0 game. Moments later, Torbett was able to waltz home from third on an Anderson balk, upping the SHHS lead to 4-0.
Tennessee High managed to cut the deficit to 4-1 when Davis Hall singled and eventually scored on a Cole Torbett wild pitch in the top of the fourth.
However, the Hilltoppers got that run back in the bottom of the fifth when Conner Hyatt lined an RBI single to center to score Levi, who had doubled.
TORBETT AND CO. GET IT DONE
Starting pitcher Cole Torbett, who pitched the first four innings to pick up the win, and three relievers allowed just three hits to the Vikings.
Anderson was the losing pitcher.
