Her two-run shot in the first inning helped the Lady Troopers to a 21-1 five-inning win and sweep of Independence in the opening round of the Mississippi High School Activities Association softball playoffs.
Mooreville (20-7) advances to face Winona, at home Friday and on the road Saturday in a three-game series.
"Once we got hot, everybody started hitting," said Keith, who hit her first career fastpitch homer. "I knew it was a hard it. It felt good coming off the bat."
Keith was 2 for 3 with four RBI. Miah Edmonds had four of Mooreville's 19 hits. Meagan Edmonds had three.
Mooreville sent 14 batters to the plate in the first and scored 10 runs, three on an inside-the park home run from Miah Edmonds. Sister Meagan also hit a two-run, inside-the-parker and Betsy Kingsley had an RBI.
"It's hard to bounce back from such a big hole," Independence coach Kevin Dunigan said. "They hit the ball really hard."
Junior pitcher Teri Richey (12-1) watched an unearned run score first before retiring 14 of the next 16. She struck out 10 and allowed only three hits.
"She did very well," Keith said. "I'm proud of her. She's done good coming off of shoulder surgery, getting back in the groove of things."
Walk this way
In the third, Tanner Bevill and Skylar Gregory had RBI singles and Keith drove in two more on a triple for a 15-1 lead. There were four bases-loaded walks in the fourth, as well as RBI singles from Summer Cryder and Laura Beth Blissard.
The Lady Troopers won 4-0 Saturday behind seventh-grade pitcher Hallie Donald.
"We just hit the ball well and Teri pitched well," Mooreville coach Perry Wilburn said. "We came out hitting today."
Ayla Greer took the loss for Independence (6-13-1).
