Think multi‑year reliever contracts are only for big‑name closers? Think again.
Front offices now prioritize durability and contact suppression over saves, so steady middle‑inning arms are suddenly valuable.
Teams will pay for guys who can handle 60+ appearances, keep barrels and exit velocity low, and still miss bats.
Seven underrated relievers match that profile and are poised to turn under‑the‑radar seasons into multi‑year free‑agent deals.
If this holds, teams chasing bullpen depth will pay up this winter.
Key Underrated Relievers Most Likely to Land Multi‑Year Free Agent Contracts
Teams pay multi‑year money for relievers who stay healthy and get outs. The big closers grab headlines, but front offices know that durable middle relievers and lefty specialists win games at a fraction of the cost. The market’s gotten smarter. Analytics departments don’t just chase saves anymore, they’re hunting peripherals that predict staying power and workload that keeps roster spots filled.
You can spot multi‑year candidates pretty easily. Almost all of them clock ERAs under 3.50 across 50‑plus innings, keep WHIP below 1.25, strike out batters at above‑average rates, and limit hard contact through exit velocity numbers in the bottom third. But durability? That’s the real tell. We’re talking 60‑plus appearances or 65‑plus innings, proving the arm can handle modern bullpen deployment without falling apart.
Seven guys match this profile heading into 2026 free agency:
• Michael Kopech threw just 11 innings after getting hurt, but posted a 2.45 ERA with 12 strikeouts, zero barrels allowed, and a sub‑40% hard‑hit rate. The 24% walk rate’s a little scary though.
• Pierce Johnson appeared in 65 games with a 3.00 ERA, struck out 59 in 59 innings, posted a 1.20 WHIP, and held opponents to a .292 xwOBA against his curveball (which he throws 72% of the time).
• Danny Coulombe has a 2.64 ERA across 190 appearances since 2021, allowed just 87.5 MPH average exit velocity in 2025, and gave up barrels only 5% of the time.
• Jakob Junis posted a sub‑3.00 ERA in 65‑plus innings. Opponents hit .167 against his changeup.
• Jacob Webb put up a 3.00 ERA across 66 innings for Texas, a 1.03 WHIP that ranked fourth among Rangers relievers, kept exit velocity under 87 MPH, and landed in the 85th percentile or better in barrel rate and hard‑hit rate.
• Tyler Kinley threw a career‑best 72.2 innings with a 3.96 ERA after escaping Colorado, allowed 87 MPH average exit velocity, and ranked 100th percentile in hard‑hit rate with a sub‑30% mark.
• Justin Wilson logged 61 games with a 3.35 ERA and posted a 31.9% whiff rate that landed in the 91st percentile.
Durability separates the guys who get multi‑year deals from the ones signing minor league invites. Front offices will pay for relievers who can handle 60‑game workloads or 65‑plus innings without losing velocity or breaking down mechanically. Add in peripherals that prevent damage (barrel rates under 6%, exit velocities below 88 MPH, elite whiff rates) and you’ve got a roster anchor worth guaranteeing across multiple seasons. It’s cheaper than replacing that arm every winter.
Contract Trends in the Free Agent Market for Underrated Relievers
Durable relievers get multi‑year deals because they solve a supply problem. Only 43 right‑handed relievers hit 65 or more appearances in 2025, and even fewer did it with sub‑3.50 ERAs. Teams that lock in proven 60‑appearance arms skip the annual scramble for middle‑relief innings. That saves roster spots and cuts transaction costs over the life of the contract. Multi‑inning capability? That’s another premium, since clubs increasingly want pitchers who can bridge two frames and limit bullpen churn during high‑leverage stretches.
Rising bullpen usage creates constant demand for matchup specialists and role‑flexible arms. Left‑handed relievers command premiums because lineup construction leans toward right‑handed power, making lefty specialists valuable even in limited roles. Teams also pay for versatility. Pitchers who can handle the sixth inning one night and protect a lead in the eighth the next offer strategic options that single‑role guys can’t.
| Role Type | Typical Multi‑Year Contract Range |
|---|---|
| Multi‑inning / high‑availability arms | 2 years, $8–18M total |
| Trusted veteran lefty specialists | 1–2 years, $3–10M total |
| High‑upside recovered / injury‑risk power arms | 1–2 years, $3–8M guaranteed plus performance incentives |
| Proven middle‑leverage bridge options | 2–3 years, $10–18M depending on leverage role |
Player‑by‑Player Breakdown of Relievers Projected for Multi‑Year Deals
These relievers mix 2025 production with role clarity and health signals that point toward guaranteed multi‑season contracts. Each profile breaks down the specific metrics and pitch traits scouts and front offices use to justify commitments beyond one year.
Michael Kopech – Why He’s Undervalued
Kopech threw just 11 innings in 2025 because of injury but logged a 2.45 ERA with 12 strikeouts while allowing zero barrels and limiting hard contact below 40%. His four‑seam still hits triple digits and generates swing‑and‑miss at elite rates when he’s healthy. Teams willing to bet on upside will offer one or two years loaded with performance incentives, gambling that his arm bounces back and the walk rate (over 24% in limited work) tightens with consistent innings.
Pierce Johnson – Why He’s Undervalued
Johnson appeared in 65 games for Atlanta, struck out 59 in 59 innings with a 3.00 ERA and 1.20 WHIP. He threw his curveball 72% of the time and held opponents to a .292 xwOBA against it. His durability jumps out. Only 43 right‑handed relievers reached 65 appearances in 2025. Plus, he can handle multi‑inning assignments, making him a bridge piece for contenders who want steady late‑inning depth without closer‑level salary commitments.
Danny Coulombe – Why He’s Undervalued
Coulombe’s posted a 2.64 ERA across 190 appearances since 2021, with 175 strikeouts and just 15 homers allowed. In 2025 he kept his barrel rate at 5% and held opponents to 87.5 MPH average exit velocity. Both are markers of elite contact suppression. His slider‑changeup mix neutralizes lefties while staying effective against righties, making him a matchup weapon with enough versatility to pitch high‑leverage innings no matter the lineup.
Jakob Junis – Why He’s Undervalued
Junis logged 65‑plus innings for Cleveland with an ERA under 3.00, entering his 10th MLB season with new effectiveness as a multi‑inning reliever. Opponents hit just .167 against his changeup, which he pairs with a mid‑90s fastball to generate weak contact and limit barrels just above 6%. His ability to bridge two or three innings reduces bullpen churn, and his track record of staying healthy across a full season makes him a safe bet for teams wanting innings stability.
Jacob Webb – Why He’s Undervalued
Webb threw 66 innings for Texas with a 3.00 ERA and 58 strikeouts, posting a 1.03 WHIP that ranked fourth among Rangers relievers. He kept average exit velocity under 87 MPH and landed in the 85th percentile or better in barrel rate, hard‑hit rate, and exit velocity. His sinker‑slider pairing generates groundballs and limits damage, making him a perfect middle‑leverage option for clubs that value contact management and consistency over flashy strikeout numbers.
Tyler Kinley – Why He’s Undervalued
Kinley posted career‑best numbers after leaving Colorado, throwing 72.2 innings with a 3.96 ERA for Atlanta. He limited opponents to 87 MPH average exit velocity and a hard‑hit rate under 30%, ranking in the 100th percentile. His fastball‑slider combo plays way better outside Coors Field, and the improvement in WHIP below 1.20 signals real skill gains rather than park‑driven noise. Teams hunting breakout candidates at low cost will target him for two‑year deals with upside incentives.
Justin Wilson – Why He’s Undervalued
Wilson appeared in 61 games for Boston with a 3.35 ERA and 57 strikeouts, posting a 31.9% whiff rate that ranked in the 91st percentile. His slider’s still a weapon against left‑handed hitters, and his ability to face multiple batters per outing adds flexibility for managers. At 37 heading into 2026, he brings veteran savvy and proven matchup value, making him a smart one or two‑year signing for contenders needing left‑handed depth without long‑term financial exposure.
Taylor Rogers – Why He’s Undervalued
Rogers pitched 50.2 innings across three teams at age 34, posting a 3.38 ERA with 53 strikeouts. His sweeper generated a .204 opponent xwOBA, proving the pitch still works even as his fastball velocity drops. Teams value his experience in high‑leverage spots and his ability to handle both matchup work and full innings. A two‑year deal in the $3–8M range offers cost efficiency for clubs wanting veteran left‑handed stability without closer‑level commitments.
Why Teams Are Targeting Multi‑Inning and High‑Leverage Underrated Relievers
Scarcity drives value. Only 43 right‑handed relievers appeared in 65 or more games during the 2025 season. Even fewer managed sub‑3.50 ERAs while hitting that workload threshold. Teams that lock up durable arms gain flexibility. They can deploy these pitchers in multiple roles, reduce roster churn, and skip the constant waiver‑wire scramble to replace injured or ineffective middle relievers. Cleveland’s bullpen posted a 3.62 ERA that ranked fifth‑best in baseball in 2025, built mostly on depth pieces who could handle 60‑plus appearances without breaking down.
Multi‑inning relievers like Jakob Junis have rising value because they solve two problems at once. They bridge gaps between starters and closers. And they absorb innings during blowouts or extra‑inning games without forcing managers to burn high‑leverage arms. Front offices increasingly want this versatility, as roster construction favors pitchers who can throw two or three frames on short rest rather than specialists limited to single‑batter matchups. Boston’s bullpen ranked second‑best in baseball in 2025 ERA, driven partly by arms capable of multiple‑inning assignments that preserved closer availability.
Elite contact suppression fits modern analytics models better than strikeout‑only profiles. Pitchers who limit barrels below 6%, hold exit velocity under 88 MPH, and rank in top percentiles for hard‑hit rate generate outs without relying only on swing‑and‑miss. Danny Coulombe’s 87.5 MPH average exit velocity and 5% barrel rate show this profile. He prevents damage rather than just missing bats. Teams targeting multi‑year deals prefer these low‑damage arms because the skills age better and stay effective even when velocity declines.
Best Potential Landing Spots and Team Fits for These Multi‑Year Contract Candidates
Contenders wanting immediate bullpen upgrades will target proven veterans with track records in high‑leverage situations. Teams needing left‑handed depth will pursue Danny Coulombe, Justin Wilson, and Taylor Rogers, all of whom offer matchup value and experience in playoff‑caliber bullpens. Clubs chasing division titles want arms who can step into defined roles without adjustment periods, making durability and recent production the main filters.
Rebuilding clubs willing to gamble on upside focus on injury‑recovery candidates and post‑Coors bounce‑back arms. Michael Kopech’s elite stuff paired with injury risk makes him attractive to organizations that can afford rehab time and benefit from trade‑deadline flips if he performs. Tyler Kinley’s career‑year after leaving Colorado offers similar appeal. Teams with player‑development infrastructure can buy low on skills that were suppressed by park factors or organizational context.
Four team types most likely to sign these relievers:
• Lefty‑deficient contenders will pay premiums for Coulombe, Wilson, and Rogers, whose combined experience and peripherals address immediate needs without long‑term payroll risk.
• Clubs seeking long‑relief stability burned through multiple swingmen in 2025 and will target Jakob Junis and Pierce Johnson, both of whom logged 65‑plus innings with sub‑3.20 ERAs and can handle bridge work across two or three frames per outing.
• Analytics‑driven organizations hunting contact‑suppression value prioritize exit velocity and barrel metrics over strikeout totals and will pursue Jacob Webb and Tyler Kinley, whose elite contact‑management profiles fit models that predict sustained success even with moderate strikeout rates.
• Win‑now teams with injury‑plagued bullpens lost relievers to Tommy John surgery or other long‑term injuries and need immediate depth. They’ll sign multiple arms from this tier to create competition and redundancy, hedging against further attrition during the season.
Market Dynamics That Create Sleeper Multi‑Year Signings for Bullpen Arms
Positional scarcity pushes front offices to secure proven relievers before spring training. The gap between elite closers commanding $15M‑plus annually and mid‑tier relievers earning $4–6M creates opportunity for agents to negotiate multi‑year deals that guarantee security in exchange for modest annual salaries. Teams hedge injury risk by spreading commitments across two seasons rather than cycling through one‑year fliers. Players gain financial certainty without sacrificing significant earning potential if they outperform.
Upside relievers like Michael Kopech and Tyler Kinley often secure incentive‑heavy offers that reward performance milestones while protecting teams against regression. A one‑year deal with a club option or a two‑year pact with vesting clauses lets organizations bet on skill recovery without long‑term exposure. These structures appeal to both sides. Players gain multi‑year frameworks with upside triggers, while clubs limit downside if velocity fades or injuries recur.
Three dynamics that drive sleeper multi‑year signings:
Rising closer salaries push contenders toward mid‑tier depth. When elite closers reset markets at $18–20M annually, teams redirect budget toward two or three proven middle relievers who collectively cost less and provide greater roster flexibility than a single star closer.
Left‑handed specialist scarcity creates bidding wars. Fewer than 15 left‑handed relievers posted sub‑3.50 ERAs across 50‑plus innings in 2025, making proven southpaws like Danny Coulombe and Justin Wilson targets for competitive bidding that inflates both annual value and contract length.
Incentive structures allow low‑risk upside bets. Teams offer guaranteed base salaries in the $3–5M range with performance bonuses tied to games finished, innings pitched, or All‑Star selections, creating paths to $8–10M total value without full financial commitment if the pitcher underperforms or gets hurt.
