The MLB Free Agency pitching market contracted sharply on Sunday when Zack Littell reportedly agreed to a deal, stripping clubs still chasing rotation depth of one more viable option. With spring training camps already in full operation and Opening Day approaching fast, front offices face a narrowing window to address pitching needs through the open market.
The Littell agreement leaves Lucas Giolito and Michael Kopech as the two most prominent unsigned arms available. Both carry injury history, and both now represent low-cost, short-term solutions rather than the multi-year commitments teams prefer when building a rotation from the ground up.
Why Does the MLB Free Agency Pitching Market Matter This Late?
Late-market pitching acquisitions carry outsized weight when rosters must be finalized before a 162-game grind begins. Teams that enter April with rotation uncertainty tend to overwork their bullpens by June, and the numbers reveal a pattern: clubs that absorb a starter mid-spring training show higher reliever workloads through the first two months of the regular season. The Littell signing tightens that calculus for any club still one arm short.
Breaking down the advanced metrics on the remaining free agents, the contrast between Giolito and Kopech is instructive. Giolito is a volume innings pitcher whose 3.41 ERA in 26 starts for the Boston Red Sox last season suggests a back-end starter who limits damage without overwhelming hitters. Kopech is the opposite profile: a hard-throwing right-hander whose four-seam fastball grades out as a plus pitch but whose durability record introduces real roster risk.
The salary cap implications for signing either player are minimal by major league standards. Both would command short-term, team-friendly contracts given their injury histories and the late date on the calendar. A club willing to absorb medical risk could secure rotation depth at a fraction of what comparable innings cost in November or December.

Lucas Giolito posted a 3.41 ERA across 26 starts with Boston last season, a workload that demonstrates he can handle a full rotation slot when healthy. That ERA sits comfortably below the American League average for qualified starters, though ERA alone understates the full picture. FIP and xFIP would add context on whether that figure reflects true run-prevention skill or favorable strand rates, but based on available data from the reported surface numbers, Giolito functioned as a legitimate mid-rotation arm in 2025.
Giolito was a 2012 first-round draft pick and turned 31 earlier this offseason. The velocity concerns that plagued him in prior seasons with the Chicago White Sox and Cleveland Guardians make his Boston rebound worth scrutinizing carefully. Tracking this trend over three seasons shows a pitcher who has rebuilt his repertoire around command and deception rather than raw stuff, which makes him more dependent on health than a power arm would be.
Kopech, a 2014 first-round selection, brings a different risk-reward equation. His fastball can miss bats at an elite rate, but his career has been interrupted repeatedly by elbow and arm problems. A team comfortable deploying him in a multi-inning relief role or a spot-start capacity could extract real value from a short-term deal. The alternative interpretation, however, is that Kopech’s injury record makes him a liability rather than an asset for a club already thin on depth.
Key Developments in the Late Pitching Market
- Zack Littell has reportedly agreed to a deal, removing one of the top available arms from the free agent pool with Opening Day near.
- Lucas Giolito, 31, recorded a 3.41 ERA in 26 starts for the Boston Red Sox during the 2025 season, making him the top remaining starting pitcher on the market.
- Giolito was selected in the first round of the 2012 MLB Draft, giving him over a decade of major league experience to offer a contending or rebuilding club.
- Michael Kopech, a 2014 first-round pick, brings elite velocity but carries documented injury concerns that depress his market value despite his raw stuff.
- Both Giolito and Kopech are now positioned as low-risk, short-term options rather than multi-year rotation cornerstones, reflecting the late timing of any potential deal.

Contending clubs that have not addressed rotation depth face the starkest tradeoff. The free agent pool for starting pitchers is nearly exhausted, which means teams must choose between signing Giolito or Kopech at reduced cost, pursuing a trade, or promoting an internal candidate from the minor league system. Each path carries distinct draft strategy analysis and salary cap implications that front offices must weigh against their competitive window.
For rebuilding clubs, the calculus is different. A one-year deal for Giolito at a discount provides a veteran presence in the rotation while the organization develops younger arms. His 26-start workload last season demonstrates he can eat innings, which has real value for a team trying to limit wear on a bullpen through a developmental year.
The waiver wire and trade market will absorb some of the demand that free agency can no longer satisfy. Teams that missed on Littell and cannot close a deal with Giolito or Kopech will pivot to internal options or explore mid-season transactions. Based on available data, the open market for impact starting pitching is functionally closed for 2026, and any remaining moves will reflect that scarcity in both price and fit.
The broader defensive scheme breakdown for pitching-needy clubs now shifts toward bullpen construction and opener strategies. Several contenders have already demonstrated comfort with bulk reliever models, and a thin starter market accelerates that trend. Giolito’s ability to pitch deep into games gives him a clear edge over Kopech in that context, since an opener-plus-bulk approach still requires a reliable multi-inning arm to follow the first pitcher through the order a second time.
