The title was the Tigerettes first solo regular season crown since 2006.
MCHS head coach Holly Cook said about the crown, "It feels great, that was our goal and now the next goal is the district tournament championship. We weren't that last year. We were runner-up last year, so our goal is to get that first and then look ahead to the region after that."
Wallace struck out 8; walked 1 and her only run allowed came via a 7th inning homerun by Shelby Hoppe.
Wallace also went 3-4 at the dish with an RBI in a twelve-hit Tigerette offensive attack and the score could have been a lot worse as MCHS left 12 runners stranded in the game.
Brianna Roberts was 2-4 with a run scored and an RBI and Danielle Toseland also went 2-4 with a run scored.
Mary Medley drove home one run on sacrifice fly and had 1 hit in 3 at bats.
Brandie Jett scored twice in a 1-4 night and Austyn Whaley made some sparkling plays at second base and had one hit and a sac bunt.
Morgan Moyers and Kathryn Haislip had Marshall County's other two hits in the contest.
Jett set the table in the top of the first with a leadoff slap hit to right field.
Whaley sacrificed Jett to second and Roberts knocked in the run with a shot to left.
Haislip and Wallace followed with back-to-back singles, loading the sacks, but the Tigerettes could not push another run across.
Wallace induced the Yellow Jackets into three easy ground ball outs in the home half of the inning and the Tigerettes were set down 1-2-3 by Kelli Ann McKinnley in the second.
Wallace came back and mowed down the home squad with some high heat, striking out the side swinging.
MCHS added a run in third, beginning with Roberts reaching base on an error.
Haislip moved Roberts over with a deep fly in foul territory down the left field line and Wallace delivered the package home, ripping an RBI single to center for a 2-0 Tigerette lead.
Wallace struck out two in the bottom of the inning and got a great defensive play behind her as Whaley dove to her right on a hot shot and fired to Kayla Harmon at first for the out.
Toseland led off the fourth with a single before McKinnley got the next two batters out.
Jett bounced a ball to third where Cierra McDonald fielded and tried to throw Toseland out at home, but the throw was high and Toseland slid under the tag.
Trish Lancaster tried to get Jett rounding the bag at first after the safe call, but the throw sailed into the right field corner and 'The Jett' took off, circling the bases for a smooth landing home, staking Wallace to a 4-0 lead.
With one out in the bottom of the inning, Collier broke up the perfect game with a base hit to left, but Wallace would not allow her or anyone else to score in the frame.
Wallace led off the fifth with her third hit of the night and Devan Hasty came in to run for the pitcher.
The Jackets went down 1-2-3 in the bottom half of the 5th and neither team scored in the 6th.
Marshall County loaded the sacks with one out in the seventh, but could not convert and Wallace went to the circle needing just three more outs to claim the regular season league title.
Hoppe led off the inning with a long home run over the center field fence.
Haislip grabbed a pop-up behind the plate for the first out and Whaley got out number two on a ground ball.
McDonald walked, extending the game, but MCHS got the job done on a ground ball to Whaley, who tagged out McDonald on her way to second, ending the game.
Cook said, "I told the girls we are about at the time where we need to be striding on up and hitting our peak and I think we are getting there slowly but surely and hopefully we can keep on rising to the top."
After travelling to Giles County tonight for the regular season district finale, the Tigerettes (27-6, 12-1) bus over to Manchester this weekend to participate in the Coffee County Spring Classic, opening up Friday at 4:00 pm versus Lincoln County (25-9).
