Right
Pitch Arsenal
Flashes up to 99 mph with good arm-side run. His best weapon when he is on.
A genuine plus pitch when he keeps it down. Pairs perfectly with the fastball to create an elite two-pitch combination.
Still developing. Command is inconsistent and the pitch does not miss as many bats as his other offerings at this stage.
Background and College Career
Spencer Schwellenbach is one of the more unique developmental stories in the Atlanta Braves system. He arrived at the University of Nebraska as a two-way player, handling shortstop duties while also taking the mound as needed. His college career reached its peak in 2021 when he won the John Olerud Award, given annually to the best two-way player in college baseball, along with Big Ten Player of the Year honors.
The Braves selected him in the second round of the 2022 draft, choosing to develop him exclusively as a pitcher. His arm tools were simply too good to risk on the other side of the ball, and the organization moved quickly to put him on a starting pitcher track through the minor leagues.
What Makes Him Special
The comparison to Spencer Strider is one Schwellenbach has had to learn to live with, and it is not entirely without merit. Both pitchers lean heavily on a high-velocity fastball complemented by a hard breaking ball that generates swings and misses at an impressive rate. Where Schwellenbach has room to grow is in his changeup development and overall command refinement, which would give him a genuine three-pitch mix capable of handling major-league lineups multiple times through an order.
His minor-league numbers through the low and high-A levels showed exceptional control for a pitcher his age, with walk rates well below league average. The stuff plays up because of how well he locates the fastball, and the slider has shown the kind of bat-missing ability that projects as a legitimate out pitch at the next level.
