SCOTTSDALE, Ariz. -- Briggs McKenzie thought the dream was over.

Growing up as a Braves fan in North Carolina, he got to live out a childhood realization when he put pen to paper and signed with the organization as a fourth-round pick in the 2025 Draft, receiving an over-slot bonus of $3 million (roughly late first-round money) to forgo his commitment to LSU.

He rocketed through the system, making just three starts in the Rookie-level Florida Complex League this May before his stuff so convincingly overwhelmed batters that Atlanta felt comfortable sending him to Single-A Augusta for his full-season debut on June 5. Once there, he spun five scoreless frames with eight strikeouts. But then he got called into manager Brad Stoll's office.

"They said, 'McKenzie, we gotta talk to you,' very straight-faced," McKenzie recalled. "I thought, to be honest, I got traded or something, just based off their reaction.

"And then they said, 'Congratulations, you're going to [High-A] Rome,' and my heart dropped and I was pumped up after that, so that was pretty cool."

The southpaw was one of just four high school pitchers from the 2025 Draft class to make it to High-A this year. It's rare that 19-year-olds reach the level in their debut season, but it's even more rare that they find themselves in the Arizona Fall League soon after. McKenzie is the youngest pitcher on the premier prospect circuit in 2026 and the first to throw in a game at age 19 since Alessandro Ercolani (Pirates) in 2023. (McKenzie celebrated his 20th birthday on Oct. 11.)

Yet, McKenzie's first start as a 20-year-old was his best yet for Glendale. He allowed no hits across four-plus frames, retiring 12 of the first 13 batters he faced on Oct. 16. He pumped strikes -- especially of the first-pitch variety -- and collected six strikeouts, five of which came on the two versions of his fastball, four-seamer and sinker.

His heaters averaged around just 92-93 mph, but he gets above-average extension from his 6-foot-2 frame and tunnels his offerings well with his repeatable delivery. 

"I was kind of an old school guy, so I always liked Nolan Ryan, the way he attacked," said McKenzie. "Obviously, I don't look like Nolan Ryan out there, but, as far as being [going toward] the batter and coming at him, that was kind of the mindset I had."

But sit behind home plate and watch McKenzie unfurl and follow through from a funky arm slot, and the look is unmistakable: there's some Chris Sale to him.

"He was somebody that I picked up immediately," said McKenzie of the 10-time All-Star. "Being a lefty, I dropped my arm slot a little more when I got here. I wanted to kind of have similar shapes and stuff."

As a prep hurler, McKenzie gained notoriety for having a hammer of a 75-78 mph curveball. Currently graded out as a 60 on MLB Pipeline's 20-80 scouting scale, it's tied for the top breaking ball in the Braves' system and has led to him landing at No. 8 on the club's Top 30 Prospects list. In the AFL, he's been throwing it harder and getting more horizontal movement (in addition to 2,800-2,900 RPMs), leading to it being charted as a slider -- but he sees it as more of a slurve that he can manipulate throughout an outing for now, before one day branching off into two separate pitches.

"It's one of those breaking balls where your eye just can't track it," said Braves area scouting supervisor Al Skorupa, who watched McKenzie dating back to his prep days. "Even from the stands, you're like, 'How did it go there?' And he dots it both corners low, whenever he wants."

That ease of operation and ability to command the ball is a big part of what put McKenzie on the Braves' radar. The organization has found success drafting and developing high school pitching talent over the past decade, including AJ Smith-Shawver, JR Ritchie, Cam Caminiti (ATL No. 2/MLB No. 39), Owen Murphy (ATL No. 10) and others.

But it's difficult to continue that upward trajectory away from the pitching rubber. After three starts with Rome, McKenzie missed the remainder of the regular season due to nerve irritation in his left forearm, compiling just 26 regular-season innings total. Sure, it gave him more time with the things he loves away from the field (fishing among them), but it also allowed him a hard reset before coming out to the Fall League.

"The person beyond the player is such a big part of his appeal," said Skorupa of McKenzie. "Just a tough-nosed kid who loves the game, plays for the right reasons, handles adversity extremely well. And just competes his butt off."

"I just know it's really hard to hit and I've got good stuff, so I just want to throw my best stuff," said McKenzie. "I feel like the games that I kind of get myself into trouble is when I almost give the hitters too much credit and I try to paint corners and be cute. So when I just go into attack mode and throw my best against their best, I usually have good results."

Beyond the obvious benefit of the AFL being beneficial in the sense of allowing McKenzie to make up for lost innings, it also has sentimental value. Every time he takes the bump, he gets to don either the gray road uniforms with "Atlanta" emblazoned across the chest or home whites with "Braves," something generations of fans across the South have envisioned.

"It's a blessing," said McKenzie. "It feels right. It's where I'm meant to be."
