How LSU Signee Bryli Seifert Went From Six Home Runs to 19 Before Signing With LSU

The Missouri Class 4 Player of the Year hit .717 and struck out once as a senior. She traces the jump to four or five workouts a week, tougher pitching and a clear plan for every at-bat. Bryli Seifert hit 19 home runs and struck out once in 126 plate appearances during her senior season at Platte County. A year earlier, she had hit six home runs and struck out four times in 95 trips to the plate. She had only 31 more official at-bats as a senior, but she went from homering once every 12.5 at-bats to once every 4.8.

“Being a tough out is a really big deal to me,” Seifert said.

When Seifert committed to LSU in September 2025, she and her family put on LSU shirts before she called the coaching staff on FaceTime to tell them she wanted to be a Tiger. In our conversation after her commitment, she mentioned a goal she wanted to pursue before getting to Baton Rouge. She wanted to get stronger in the weight room.

By the time she signed with LSU as part of its 2027 class, that goal had become one of the biggest reasons she could explain the difference between her two seasons. Her average rose 224 points, from .493 to .717. Her slugging percentage climbed from .947 to 1.565, and she doubled her RBIs from 31 to 62. She finished her high school career as Missouri’s Class 4 Player of the Year.

The work behind the power

Seifert spent the past year training for speed and strength about four or five times a week. Her dad, a strength and conditioning coach, coordinated the work in the weight room. The difference showed up on swings she didn’t catch cleanly.

“I’ve noticed the biggest difference in my power at the plate, especially with my exit velocity and being able to drive the ball even when I don’t make perfect contact,” Seifert said.

Her uncle, who is also her hitting coach, helped her simplify what she was thinking about in the box. She wanted to stay relaxed and look for a pitch she knew she could drive. Early in an at-bat, that means focusing on one quadrant of the strike zone. With two strikes, she’s prepared to foul off a pitch outside that area or put it in play. She starts gathering information before she steps in, watching how the pitcher works against her teammates.

That approach helps explain how the power surge came with fewer strikeouts. Seifert had a specific pitch she wanted to attack early and a plan to stay in the at-bat if she never saw it. She also drew 30 walks, up from 12 the previous season. Perhaps the most impressive stat that she logged in her senior season is only striking out once through the regular season and the playoffs.

Learning to adjust against tougher pitching

Seifert had already moved up to 18U with Top Gun when we first spoke. At the time, she said the game moved faster and forced her to adjust more quickly. A year later, she pointed to those at-bats as part of what prepared her for her senior season. She credited coach Bob Turner and Top Gun for seeking out strong competition and giving her regular looks at quality pitching. “Moving up to 18U taught me that I couldn’t always rely on what had worked for me before,” Seifert said. “The competition was tougher, the game was faster, and I had to learn how to make adjustments quickly.”

Through 14 games with Top Gun National 18U this fall, Seifert hit .629 with a 1.955 OPS. She went 22 for 35, and 13 of those hits went for extra bases. The early travel results add another look at the bat LSU signed. What intrigues me most about Seifert as a prospect is the potential to hit for power while staying competitive deep in counts. Her next goal is to become more comfortable driving strikes in parts of the zone she doesn’t look for early in an at-bat. “I never want to become a predictable hitter,” Seifert said. “I want to be able to hit pitches in different areas of the zone and make pitchers work instead of only being successful when I get my favorite pitch.”

From Platte County to Baton Rouge

Closing out her high school career meant saying goodbye to teammates she had grown up with. Seifert said she still hadn’t fully processed that she wouldn’t play with them again. What she’ll miss most is competing alongside them, pushing one another and celebrating the little moments together.

She’s already had a chance to make some of those memories with future LSU teammates. The friendships started to take shape when members of the 2026 and 2027 classes went to the LSU–Texas A&M series in the spring. Later, at a travel tournament in Colorado, they got together for dinner. When I asked which memory stood out, Seifert recalled the group joking around and playing games at the table.

Watching the 2026 class get on campus and compete this fall gave Seifert a better picture of what awaits her. Signing brought her back to that FaceTime call with her family in LSU shirts and the coaches on the other end. This time, some of the players she’ll join in Baton Rouge are already friends.

“This has been a dream of mine for a long time,” Seifert said, “and being able to share this moment with my family, who have supported me and sacrificed so much along the way, makes it even more special.”
