After the Chicago Cubs lost to the St. Louis Cardinals on Saturday afternoon by a score of 8-4, there will be a rubber match between the two NL Central foes on Sunday afternoon.
Saturday’s game will dominate MLB headlines for all the wrong reasons on the Cubs’ side, as Cardinals’ rookie Joshua Baez clubbed three home runs in his MLB debut. Matthew Boyd served up all the homers.
However, during the Cardinals series, the Cubs announced a piece of news surrounding pitcher Shelby Miller.

Shelby Miller is a member of the Cubs organization, but he has not pitched with the club this season as he’s battling a brutal injury from last season.
On Saturday, his rehab was transferred to Triple-A Iowa, which is a good sign for the 13-year MLB veteran. The move to AAA is reflected on MiLB.com’s transactions tracker:
“Chicago Cubs sent RHP Shelby Miller on a rehab assignment to Iowa Cubs.”
ESPN.com’s Jesse Rogers wrote (on Feb. 13, 2026):
“Miller, 35, is recovering from Tommy John surgery and will miss all of the 2026 season after appearing in 48 games for Arizona and Milwaukee last year. The contract guarantees him at least $2.5 million over the two years.”
So, unless Miller appears in a game this season, the first year of that two-year, $2.5 million deal is pretty much wasted.

He did have a very brief stint with the Chicago Cubs in 2021, where he logged just two innings and allowed seven runs over that small sample size.
