Spencer Schwellenbach

24-Year-Old PitcherSP
2024 Fantasy Outlook
Atlanta gave Schwellenbach $1 million after drafting him out of Nebraska in the second round in 2021 and he had Tommy John surgery right after the draft. He put up good numbers in 2023 as a 23-year-old in the lower levels, but his stuff ticked up in 2024, with his fastball going from a 93-94 mph pitch to a 95-96 mph offering. He generated groundballs over 55 percent of the time at High-A and Double-A and was surprisingly summoned to the big-league rotation after just two starts at Double-A. There's nothing about Schwellenbach's arsenal or command that would cap his short-term potential, but even as an older prospect, it's quite the jump in competition to the majors after logging only 13 innings above High-A, so there could be some understandable bumps in the road.

Schwellenbach is not on Atlanta's roster for the National League Wild Card Series against the Padres.
ANALYSIS
It's not a surprise after Schwellenbach threw 94 pitches over seven innings in the first game of Monday's doubleheader against the Mets. If Atlanta advances to the NLDS, Schwellenbach will undoubtedly be part of the rotation for that series.
