3:12pm: The two sides have a deal in place, per ESPN’s Jesse Rogers. Miller is guaranteed $2.5MM over two years but can boost that further based on 2027 incentives.
1:25pm: The Cubs and right-hander Shelby Miller are finalizing a multi-year, major league contract, reports Robert Murray of Fansided. The Excel Sports client is expected to miss the 2026 season after undergoing UCL and flexor surgery in mid-October. As such, it’ll likely be a backloaded two-year arrangement that allows Miller to rehab with the Cubs in 2026 with an eye toward joining their bullpen in 2027.
Miller, 35, has had an unusual career arc. The 2009 first-rounder was a top prospect with the Cardinals and finished third in NL Rookie of the Year voting back in 2013. He spent two seasons with St. Louis before being traded to Atlanta for Jason Heyward in the 2014-15 offseason. The Braves got 33 excellent starts out of Miller in 2015 before trading him to the D-backs in a lopsided blockbuster that sent Dansby Swanson — just six months removed from being the No. 1 overall pick in the draft — Ender Inciarte, and former first-rounder Aaron Blair back to Atlanta. Miller’s time in Arizona was an injury-plagued nightmare; he pitched to a 6.35 ERA in 139 innings over the course of three seasons before being cut loose.
Miller bounced around the league for several seasons without much success — including a two-inning stint with the 2021 Cubs, where he was tagged for seven runs — but he’s found a second act to his career as a late-inning reliever. Over the past three seasons, he’s suited up for four clubs, including a much more successful return tour with the D-backs in 2025. Since Opening Day ’23, he’s posted a 3.13 ERA with a strong 25.3% strikeout rate, an 8.2% walk rate, 13 saves and 17 holds in 143 2/3 innings.
Last offseason, Miller and the D-backs agreed to a one-year pact that yielded outstanding results. He pitched 36 1/3 innings for Arizona and turned in a dominant 1.98 earned run average with a 28% strikeout rate. The reunion was cut short by a forearm injury, and the Brewers traded for Miller at the deadline while he was still on the 15-day IL.
Miller went on to make 11 appearances with Milwaukee, pitching well in August before making one lone appearance in September. He faced two hitters, allowing both to reach base, and called for a trainer after feeling what he described as a “pop” in his elbow. Miller later told the Brewers’ beat that an internal brace procedure and flexor repair was presented as an option when he was first placed on the injured list with the Diamondbacks. He wanted to continue to try to pitch that season, knowing he’d likely need eventual surgery and that doing so could mean a full Tommy John procedure, which comes with an even longer rehab window than an internal brace.
The Brewers were aware of the risk at the time they traded for Miller, which is why they didn’t send a prospect back to Arizona but rather just took on $2MM of the $22.5MM Arizona was paying left-hander Jordan Montgomery last year (while Montgomery was rehabbing his own Tommy John procedure). Miller ultimately had Tommy John surgery in October — the second of his career. His first came during that original run with Arizona.
Miller will turn 36 in October, right around the one-year anniversary of his second UCL reconstruction. He’ll have to go on the Cubs’ 40-man roster when the deal is finalized — players cannot be signed and placed directly on the 60-day injured list — but he’ll move to the 60-day IL as soon as Chicago needs to free up another roster spot. He’ll 16 months removed from surgery by the time pitchers and catchers report to spring training in 2027 (pending a potential lockout related to the expiring 2022-26 collective bargaining agreement).
