As we check in on some Atlanta Braves prospects participating in the Arizona Fall League, you will quickly find some promising developments. Jim Callis of MLB.com recently shared some of the Statcast darlings from the AFL, and a couple of Braves prospects were highlighted in Callis' article.
Braves No. 3 prospect, Tate Southisene, ranks in the top five in average exit velocity (95.5 mph). Meanwhile, Atlanta's No. 29 prospect, Isaiah Drake, has the highest sprint speed (31.1 ft/sec) in the AFL. While each of these prospects is showcasing their impressive tools, plenty of work remains for the latter if he hopes to establish himself as a future Major League piece.

Isaiah Drake still has a lot to prove if he wants to become a viable Major League piece for the Braves
Unsurprisingly, Southisene is one of the prospects making noise in Arizona. Most Braves fans know Southisene has an extremely high ceiling and expect the infielder to contribute in Atlanta within the next few years. Conversely, Isaiah Drake has a much tougher road to Atlanta.
Drake is 21-years-old, but his pedigree is not that of Southisene's. Drake's bat took a little longer to develop, and last season was the first time we saw some workable power in his game. Drake slugged over .400 for the first time in 2026, and he is still learning how to utilize his incredible sprint speed on the bases.
Drake was 19-for-26 in stolen base attempts in 68 games at High-A Rome this season, so it's clear he still has work to do in his development. The good news is Drake is putting together a solid campaign in the AFL. In 39 plate appearances, Drake has eight hits and a 20.5% strikeout rate, building on the improved contact skills he displayed last season.
Many Braves prospects took a huge leap in 2026, and the system is better off because of that. Still, it is important to remember that every prospect's development is not linear, and some will ride the progression rollercoaster more than others. Tate Southisene and Isaiah Drake are progressing at their own rate, but each are at least moving in the right direction.
