Is Spencer Schwellenbach the Next Big Thing or Just a Flash in the Pan? 

Spencer Schwellenbach is generating quite the buzz as we head into the 2025 season, but opinions on his potential are sharply divided. Some analysts, like Lance Brozdowski, express skepticism about his ability to build on a promising rookie campaign, while others see a bright future ahead. With a 3.29 FIP over 123.2 innings, Schwellenbach certainly has the numbers to back up the hype, but can he truly elevate his game?

What intrigues me most is the unpredictability of his pitching arsenal. With metrics showing high scores in Pitch Type Probability and Surprise Factor, Schwellenbach seems to keep hitters guessing. But is unpredictability enough to ensure long-term success? Can he refine his approach against left-handed hitters, who have shown some success against him?

I’m curious to hear your thoughts. Do you believe Schwellenbach can take the leap and become a top-tier starter, or do you think he’s hit his ceiling? What adjustments would you suggest he make to improve his performance against lefties? And for those who have followed his career closely, what are your expectations for his 2025 season?
