5 Underrated Free Agents Who Could Be Game-Changers (2026)

Think the free-agent market is all dried up? Think again. While the big names are grabbing headlines, there's a whole tier of players flying under the radar who could be absolute steals for savvy teams. Sure, the top 30 free agents are still largely unsigned, but the real intrigue lies in the players who didn't even crack that list. These are the guys who might just outperform expectations and become the unsung heroes of the 2026 season. But here's where it gets controversial: Are we underestimating these players because they don't have the flashy stats or the household names? Or is there something more to their potential that we're missing? Let's dive in and find out.

First up, let's talk about Justin Verlander. At 43, he's no spring chicken, and his 2024 season with the Astros was, frankly, a disaster. But here's the twist: Verlander made some serious adjustments last summer, including adding a sweeper to his arsenal that completely baffled hitters. Over his final 13 starts, he posted a 2.60 ERA and a .053 batting average against that pitch. And this is the part most people miss: Verlander may not be a Cy Young contender anymore, but he's far from done. If he can maintain that level of performance, he could be a game-changer for a team looking for veteran leadership and reliable innings. Question for you: Is Verlander's resurgence a fluke, or is there still enough gas in the tank for him to be a top-tier starter?

Next, let's shift to Harrison Bader, the speedster with a glove that's pure gold. At 32, you'd think his speed might be declining, but his 28.8 feet per second sprint speed ranked in the 85th percentile last season. But here's where it gets controversial: Bader isn't just a defensive specialist anymore. Last year, he posted a career-best 122 wRC+, proving he can hold his own at the plate. Even if he regresses to league average, his speed and defense make him a valuable asset. Thought-provoking question: Are we selling Bader short by focusing too much on his age, or is he truly entering a new phase of his career?

Now, let's talk about Zack Littell, the unsung hero of the rotation. Littell isn't going to blow anyone away with his fastball, but he's a master of control and adaptability. Last season, he set career highs in starts and innings pitched, and his 4.2% walk rate was the lowest among qualified starters. And this is the part most people miss: Littell has transformed his approach, ditching a fastball-heavy strategy for a diverse five-pitch mix that keeps hitters guessing. Controversial take: Could Littell be the next great 'under-the-radar' starter, or is he just a product of a weak market?

Moving to the bullpen, Michael Kopech is a name that hasn't been generating much buzz this offseason, thanks to an injury-plagued 2025. But here's the twist: when healthy, Kopech is one of the most dominant relievers in the game. His 100 mph fastball and low-90s cutter are still elite, and he's only 29. Question for you: Is Kopech a high-risk, high-reward signing, or is he a no-brainer for a team willing to take a chance on his health?

Finally, let's not forget Rhys Hoskins, the slugger who's been battling injuries for the past few years. Before his ACL tear in 2023, Hoskins was a consistent power threat with an .845 OPS and 148 home runs over six seasons. But here's where it gets controversial: Despite limited playing time last season, Hoskins posted a 46.4% hard-hit rate and an 11.6% walk rate, both career bests. Thought-provoking question: Is Hoskins a prime candidate for a bounce-back season, or are his injury concerns too great to ignore?

These players might not be the flashiest names on the market, but they all have the potential to outperform expectations and make a significant impact. The real question is: Which one of these under-the-radar signings will be the steal of the offseason? Let us know your thoughts in the comments!
