As a whole, the 2026 offseason stands in stark contrast to the disappointing winter that preceded a disappointing 2025 season. The Orioles made a major signing in slugger Peter Alonso, made major trades for Taylor Ward and Shane Baz and acquired Andrew Kittredge and Ryan Helsley to bolster the bullpen. However, one feeling remains the same from last offseason: the starting rotation still seems unfinished.
Despite the addition of Baz, the Orioles’ front office has failed to add a pitcher who can push Kyle Bradish and Trevor Rogers for the top spot in the Baltimore rotation. There have been some swings and misses, too. The O’s were reportedly interested in Ranger Suárez before the lefty landed in Boston on a five-year, $130M deal. The Orioles were also seen as potential front-runners in the race for former Astros southpaw Framber Valdez, before he signed with Detroit for $115M over three years.

With other starters like Dylan Cease, Michael King and Tatsuya Imai long off the board, there is one pitcher left who has the potential to truly upgrade the Orioles rotation. Enter former Diamondbacks’ All-Star Zac Gallen. While the right-hander is far from a sure thing, he offers an upside unmatched by the remaining free agents—a potential I believe the Orioles can unlock.
All-Star upside with room for improvement
Unlike Suárez and Valdez, Gallen is not coming off a good 2025 season. Arguably, the whole reason the Diamondbacks let Gallen reach free agency was the disappointment of this past season, when the former Cy Young finalist posted a 4.83 ERA, saw his K/9 drop to a career-low 8.2 and had his H/9 and HR/9 balloon to career-worsts.
Trying to explain Gallen’s sudden dip in form is tricky. His batting average against was largely unchanged from the previous seasons, while his BABIP actually went down. His average exit velocity and hard-hit rate also remained largely unchanged when compared to his previous, more successful seasons. His pitch velocities also remained largely unchanged.

What stands out as a potential cause of his regression was a trend that saw him leave the ball up and over the middle of the plate more. When Gallen was consistently a Top 5 pitcher in the NL in 2022 and 2023, he attacked the zone with his fastball and cutter while using his knuckle curve and changeup to attack below the zone and generate strikeouts. Last year, Gallen saw his fastball catch too much of the plate while also leaving his curveball up more than he’d ever done. These struggles to command the right parts of the zones led to a career-high 30.3% fly ball rate, which in turn saw his home run rate and slugging percentage against rise to career-worsts.
Gallen also seems to be in the midst of a minor identity crisis when it comes to how he uses his five-pitch mix. Declining confidence in his fastball and cutter saw him lean more than ever on his changeup last year, with the off-speed offering ranking as his best pitch for the first time in his career. Whether that increased change up usage can be refined to return to All-Star form is yet to be determined.
However, we’ve seen the Orioles help pitchers like Bradish, Rogers and Zach Eflin tinker with their pitch mix to great effect. If the pitching coaches and analytics can get their hands on Gallen, there’s reason to believe they can unlock the version of him that put up a 3.20 ERA while averaging 9.4 K/9 across 2022, 2023 and 2024.
Best fit for the Orioles’ timeline
As he heads into his age-30 season, Gallen is two years younger than Valdez and at least seven years younger than other rumored Orioles targets Chris Bassitt and Justin Verlander. While the Orioles may be one move in the rotation from truly being able to compete for an AL East title, AL pennant and World Series title in 2026, they’re also not only trying to compete in this upcoming season.

Of the Orioles’ current projected starters, only Zach Eflin is over 30 and only Rogers is scheduled to be an unrestricted free agent after the 2026 season. A consistent frustration throughout Birdland is the front office treating the rotation as a patchwork quilt that needs to be cut up and reimagined every offseason. Signing Gallen to a multi-year deal would give the rotation the foundation it needs to open a window for prolonged contention—something that’s eluded the Orioles since the 70s.
Gallen also carries less injury risk than a lot of the remaining free agent starters. Other reported Orioles target Lucas Giolito missed the first month of last season with a hamstring injury and has two Tommy John surgeries in his medical history. On top of being 43, Verlander has missed time in each of the last three seasons with a variety of leg, shoulder and neck injuries.
Comparatively, Gallen has been the picture of health. The 6’2” right-hander has only had two significant injuries in his career, a hamstring strain that cost him most of June in 2024 and an elbow sprain that shelved him for five weeks in 2021. Given the lengthy medical files of several other Orioles starters, adding a proven workhorse would be a big boon for the Baltimore rotation.
