Cubs Sign Shelby Miller: Veteran Lefty Nearing Deal

The Chicago Cubs are finalizing a backloaded, multi-year deal with veteran right-hander Shelby Miller. He’s a pitcher whose career has spanned dazzling upside and major injuries.

The contract is worth $2.5 million guaranteed over two years, with incentives that could push the total higher through 2027. The deal is set up to support Miller’s rehab in 2026 and, if things go well, bring him back to a late-inning bullpen role for Chicago in 2027.

Miller, 35, will likely miss the 2026 season after undergoing UCL reconstruction (Tommy John) and flexor surgery in mid-October. This setback tests the Cubs’ bullpen depth and his long-term viability.

Cubs, Miller Agree to Backloaded Contract

The agreement looks to be backloaded, cushioning Miller’s path to recovery while giving him a clear target for a return to high-leverage work. The Cubs plan to place him on the 40-man roster once the deal is finalized.

They’ll use the 60-day injured list as needed, with the expectation that he’ll be roughly 16 months post-surgery by pitchers and catchers reporting in 2027. This arrangement matches Chicago’s plan to rehab Miller in 2026 and try him in the bullpen in 2027.

Contract Details and Timeline

Key terms: It’s a multi-year major-league contract that guarantees Miller $2.5 million over two years, plus incentives through 2027. The structure is meant to reward durability as he comes back from two Tommy John procedures, the second coming after a forearm issue with the Brewers in 2025.

Miller’s 2026 season will be about rehabilitation, with a possible spring 2027 reintroduction to competition for a bullpen role.

Medical milestones: Miller had UCL reconstruction and flexor repair in mid-October, marking his second Tommy John surgery. The Cubs want to manage his injury status and use the extra time to help him re-enter game action in a controlled, gradual way.

From Prospective Ace to Late-Inning Reliever

Miller’s arc in pro baseball has been dramatic. A 2009 first-round pick, he finished third in NL Rookie of the Year voting in 2013 and quickly became a marquee name.

A trade from St. Louis to Atlanta for Jason Heyward helped shape a controversial, blockbuster deal that sent Dansby Swanson to the Braves. That set off a chain of moves that defined both franchises in the mid-2010s.

Miller’s stint in Arizona was rough, plagued by injuries and uneven performance. He posted a 6.35 ERA across 139 innings over three seasons.

He later reinvented himself as a late-inning reliever. Since Opening Day 2023, he’s delivered a sharp 3.13 ERA with a 25.3% strikeout rate, 8.2% walk rate, 13 saves, and 17 holds over 143 2/3 innings.

His 2025 rebound with the D-backs—1.98 ERA in 36 1/3 innings—looked like the stream of form the Cubs hoped to recapture. A forearm injury cut that momentum short.

A late-2025 trade to the Brewers propelled him into postseason plans, but a “pop” in the elbow led to a second Tommy John procedure in October.

Path to 2027: Rehab, Return, and Role with Chicago

The Cubs envision a measured ramp for Miller, using the 60-day IL to his advantage as he completes rehab. If things break right, he could rejoin Chicago’s bullpen in the latter half of 2027.

He’d provide organizational depth and a veteran presence for a team otherwise building toward a competitive window. The backloaded structure reflects a pragmatic approach: let Miller rehab in-house, keep tabs on his progress, and reintroduce him when he’s equipped to help as a multi-inning reliever or closer during crucial late-season stretches.

Career Milestones: Shelby Miller’s Roller Coaster

• 2009: First-round draft pick with high expectations.
• 2013: Third-place finish in NL Rookie of the Year voting.
• Trades: St. Louis traded him to Atlanta for Jason Heyward. Later, he became part of a huge deal to Arizona that included Dansby Swanson and more.
• Arizona years: Injuries and inconsistency haunted him, and he posted a 6.35 ERA over 139 innings across three seasons.
• Reliever reinvention: Starting in 2023, he found new life as a late-inning reliever. He put up a 3.13 ERA, struck out 25.3% of batters, walked 8.2%, and notched 13 saves and 17 holds in 143 2/3 innings.
• 2025: He dominated with a 1.98 ERA over 36 1/3 innings for the D-backs before a forearm injury cut things short. They traded him to the Brewers at the deadline.
• October 2025 onward: He underwent a second Tommy John surgery—the second big reconstruction on his elbow. That pushed back any possible Cubs debut to 2027.

The Cubs see Miller as a low-risk, high-upside gamble. If he can get through rehab, who knows? Maybe his best moments are still out there. For Miller, it’s a shot to prove he belongs in a contender’s bullpen again, with plenty of time to show he can still deliver when it matters.
