Cubs Lefty Bullpen Churn Just Took Another Turn

Veteran pitcher Drew Pomeranz seeks a fresh start in free agency after a rocky season with both the Cubs and Angels.

Drew Pomeranz is back on the open market.

According to the MLB.com transaction tracker, the veteran left-hander elected free agency after the Cubs designated him for assignment on Monday and placed him on waivers. It closes the book on a short second stint in Chicago that never found the same footing as his surprisingly strong minor league pickup in 2025.

The big league results this time around just weren’t there. Pomeranz allowed five runs on seven hits and four walks across 5 2/3 innings, and he struck out only one of the 27 hitters he faced.

That came after an earlier rough stretch with the Angels, where he signed a $4MM free agent deal over the winter, posted a 5.01 ERA, and worked with a well below-average 14.8% strikeout rate over 23 1/3 innings. Los Angeles moved on quickly, and the Cubs’ reunion didn’t change the story.

That’s a sharp fall for a pitcher who looked so much more like himself a year ago. Pomeranz struck out 28% of opponents on the way to a 2.17 ERA in 49 2/3 innings last season.

The decline in his stuff hasn’t been massive, but it has been enough to matter. His average fastball has slipped from 92.7 mph to 92.1, and the pitch’s spin rate is down 59 rpm.

Hitters have punished the heater for seven home runs already, after he gave up only three all of last season.

Chicago’s bullpen picture now shifts back to Caleb Thielbar and Ryan Rolison as its two lefties. Rolison has earned more leverage work with a strong season, while Thielbar has missed plenty of bats but also given up a few too many home runs.

Hoby Milner and each have a chance to return from injuries in August, and the Cubs could still look for another southpaw on the trade market. Even so, starting pitching is expected to be the priority over the next ten days.

Mets Fans Wont Love This New Cubs Trade Prediction

Pitching help remains the Cubs obvious winter-to-deadline concern, and that has already pushed Chicago into the market once this season. CBS Sports analyst Mike Axisa recently floated a scenario in which the Cubs could keep mining the same lane, after earlier dealing for David Peterson from the Mets and continuing to look for arms that can help stabilize a staff hit by injuries and uneven performance.

The latest prediction is the kind of idea that would not sit well in Queens, because it has the Cubs circling New York again as the 2026 trade deadline approaches. Axisas case leans on recent performance and contract situations, with Freddy Peralta standing out as a possible buy-low target and Huascar Brazoban also in the mix, while Chicagos search for another reliever piece remains part of the larger picture.

Cubs Fans Just Got Another Reason To Sweat The Trade Deadline

The days leading into the Aug. 3 trade deadline already had Cubs fans bracing for movement, and two of the organizations top prospects only added to the unease. Moises Ballesteros and Kevin Alcantara each posted motivational, somewhat cryptic messages on Instagram, a small detail on its own but one that landed at a tense moment for a team expected to be active in the market.

Alcantara was recently sent back to Triple-A this week, while Ballesteros stayed put after the Cubs chose to call up James Triantos for his MLB debut instead of bringing him back to the majors. With starting pitching still the obvious area to watch, the front office has plenty to weigh as it sorts through possible upgrades, and the uncertainty around both young players is just another reason the deadline feels worth watching closely.
