The Cubs are known to be in the market for starting pitching help, and it’s not very hard to see why. Justin Steele has been out for nearly the entire season after undergoing surgery on his UCL and won’t be back until sometime next year. Jameson Taillon is currently on the injured list, as are depth arms like Javier Assad and Brandon Birdsell. Cade Horton and Matthew Boyd are having their innings carefully monitored after not getting much volume in last year. Shota Imanaga has already spent time on the injured list and has some worrisome peripheral numbers.
All of that has led the Cubs to be connected to the vast majority of rumored starting pitching options available on the trade market, ranging from depth additions like Adrian Houser, to high-value rentals like Dylan Cease and Merrill Kelly, to controllable arms like Mitch Keller and MacKenzie Gore. Reporting from ESPN’s Jesse Rogers this morning offers a fresh look at some of the other arms Chicago is taking a look at with just over 30 hours to go until the deadline. Rogers writes that the Cubs have shown interest in Orioles right-hander Zach Eflin and spoken to the Rays about their starting pitchers, while Jeff Passan of ESPN reports that Guardians righty Shane Bieber is “an option” for the Cubs.
Eflin, 31, has struggled badly this year with a 5.93 ERA and 5.60 FIP in 14 starts. A 4.39 SIERA and an absurd 19.4% home run to fly ball ratio suggest that some poor fortunate could be baked into Eflin’s results this year, but even so it’s hard to view him as more than a back-of-the-rotation addition for this season. With that being said, the right-hander does have some intriguing past success under his belt. From 2020 through 2024, Eflin tossed 583 1/3 innings of work with a solid 3.76 ERA and 3.46 FIP. He struck out 23.2% of his opponents in that time while walking just 3.9%. If Eflin can recapture that quality mid-rotation form, he could theoretically pitch in for Chicago’s prospective playoff rotation this year, though that seems unlikely to be something the Cubs (or any acquiring club) would count on.
Bieber is another potential buy-low candidate, albeit for a very different reason. He hasn’t thrown a major league pitch since early in the 2024 season after undergoing Tommy John surgery, and while he’s expected back at some point in August it’s always uncertain what sort of production a pitcher coming off major injury will be able to offer. The 2020 AL Cy Young award winner has a 3.22 ERA and 3.09 FIP for his career, however, and if he’s healthy and at his usual level of effectiveness would immediately slot in towards the top of the Cubs’ rotation.
Bieber’s contract affords him a $16MM player option with a $4MM buyout for the 2026 season. That $12MM decision figures to be an easy one for Bieber to make, and he’s all be certain to decline it and return to free agency unless he suffers some sort of new injury that would impact his 2026 campaign. Still, player options are at times viewed as a “poison pill” of sorts in trade negotiations, as the Cubs saw for themselves when they dealt Cody Bellinger to the Yankees over the offseason in what amounted to little more than a salary dump. Perhaps that could lower the acquisition cost of Bieber, making the fact that he won’t be able to immediately impact a Cubs rotation in desperate need of help more palatable.
As for the Rays, the club is routinely willing to at least listen on virtually its entire roster even when they’re buyers and appears to be leaning more towards selling in recent days. That makes it hard to know what starters the Cubs could be discussing with Tampa. Pending free agent Zack Littell has a 3.72 ERA in 21 starts this year despite shaky peripherals and could fit the sort of depth-starter mold that options like Eflin and Houser can fill. Young right-hander Taj Bradley would be an intriguing controllable addition who the Rays are reportedly willing to listen to offers on. He’s pitched to a 4.33 ERA with a 4.14 FIP over the past two seasons and is still just 24 years old.
No trade can be fully ruled out when it comes to the Rays, so perhaps someone else from the club’s rotation could be available as well. With that being said, Drew Rasmussen extended with the club through the 2027 season back in January and is approaching his innings limit this year while youngsters like Ryan Pepiot and Shane Baz are still in their pre-arbitration years. The acquisition cost for any of those three players would surely be exorbitant, however, and there have been no signals that any of those arms are even available beyond the Rays’ general tendency to listen to offers on virtually all of their players. Even by Tampa’s standards, however, a trade of one of those three would register as a major surprise.
