Unveiling the Undervalued: 4 Free-Agent Starting Pitchers Who Could Be Bargains in 2026
The free-agent market is a treasure trove of potential, but it's often a minefield of overpriced talent. When it comes to starting pitchers, the challenge is even greater. Teams shell out big bucks for these arms, with the average MLB club spending a staggering $33.8 million on their starting rotation last season. But what if we tell you there are hidden gems out there, undervalued and waiting to be discovered?
We're not talking about the big-name pitchers like Framber Valdez or Zac Gallen, who are expected to command nine-figure deals. Instead, we're focusing on the short-term deals that could be a steal for a team in need. Let's dive into four free-agent starting pitchers who might be flying under the radar but could deliver huge value in 2026.
Zack Littell: The Sneaky Inning-Eater
Zack Littell, a right-handed pitcher, might not grab the headlines, but he's a hidden gem worth uncovering. Despite not striking out batters at a high rate and having below-average Stuff+ scores, Littell excels in other areas.
Since last season, he's shared the honor of having the lowest walk rate (4.5%) among qualified pitchers with Tarik Skubal. This is a crucial skill to have, as it sets the foundation for a strong pitcher. Littell's arsenal includes a splitter and a two-seamer, giving him three types of fastballs that he throws regularly. This changeup in his pitch selection has increased his zone percentage, resulting in an impressive swing rate of 51.4% in 2025, which was tied for the sixth-best among pitchers who reached at least 150 innings.
This high swing rate leads to fewer balls, fewer walks, and more innings, as evidenced by his 11th-place ranking in innings pitched last season. Littell's performance since 2024 has been even more remarkable, with only 16 pitchers throwing more innings while posting a lower ERA than his 3.73 in that span. At just 30 years old, Littell is a young, sneaky innings-eating machine.
Aaron Civale: The Underrated Striker
Aaron Civale, a right-handed pitcher, was once a highly sought-after player, as evidenced by the Rays' trade of top prospect Kyle Manzardo for him in 2023. However, his stock has dipped due to uneven performance, with a 4.85 ERA last season and less than 1 WAR in back-to-back campaigns.
But Civale's numbers tell a different story. Among pitchers who tossed at least 40 innings in the second half of last season, he ranked 22nd in strikeout-minus-walk percentage (20.5%), an elite rate that accounts for pitchers' control. His second-half SIERA of 3.39, which also considers batted-ball quality, is the best among all remaining free-agent starters, even surpassing Valdez.
Civale's performance improvement coincided with a pitch-mix change, as he increased his curveball usage, giving him an unusual combination of a cutter-curveball that accounted for at least 50% of his offerings in the second half. This could be the formula he needs to help a rotation or as an impact swingman.
Chris Bassitt: The Durability Dynamo
Chris Bassitt, a right-handed pitcher, is entering his age-37 season, but he's a durability dynamo. He's consistently logged at least 150 innings in every season since 2021, and his arsenal is one of the deepest in the game. Bassitt's ability to get by on guile and creativity, even as his stuff declines, is a testament to his skill.
Last season, he tinkered with his pitch selection, dropping his arm angle by three degrees, which created more horizontal movement across his offerings. His curveball's run value improved from -1 in 2024 to +5 compared to the league average, and his full-season SIERA of 3.92 was better than the league average and his best since 2022. This suggests that Bassitt still has some fuel left in the tank for 2026.
Lucas Giolito: The Injury-Prone Powerhouse
Lucas Giolito, a right-handed pitcher, might seem surprising still available, but his expected ERA of 4.99 last season, which ended with a sore elbow, has raised some red flags. However, his injury history is significant, having undergone Tommy John surgery after being drafted and an internal brace procedure that cost him all of 2024.
Despite this, Giolito is still available and likely to get a low-risk, high-upside, short-term deal. The belief is that he'll be stronger a year removed from surgery and return to being a strong strikeout arm, with a 26% K-rate in 2023 and a 25% career rate. Additionally, Giolito was one of the unluckiest pitchers in baseball by one measure: performance in full counts. His K-BB% mark with a full count was -17% last season, walking 30 and striking out 17.
If Giolito can get back to neutral, he can be a mid-rotation contributor, and likely do so at a discount.
