The Astros have a clear bullpen hole to fill, and Steven Okert’s departure leaves them hunting for a left-handed arm who can step into the same kind of late-inning work.
Okert, now a free agent at 35, gave Houston two seasons of steady value. Over that stretch, he logged 2.8 fWAR and made 136 appearances, and 2026 was the best version of him yet in several key areas. He posted the lowest walk rate of his career at 1.86 BB/9, allowed a .226 BABIP and carried an 86.5 LOB%, while also cutting down the home run damage he had allowed before arriving in Houston.
That matters because the Astros don’t have an obvious one-for-one answer in-house. Bennett Sousa and Bryan King have both been inconsistent, which is why the free-agent market becomes the obvious place to look for a specialist who can handle the same kinds of spots Okert used to manage.
One name that fits the bill is Alex Vesia. The 30-year-old left-hander just finished six seasons with the Dodgers, where he was a key part of the bullpen during their back-to-back World Series runs in 2024 and 2025. Over the last three seasons, Vesia ranks fifth among qualified left-handed pitchers in fWAR at 3.3, trailing only Josh Hader among the names mentioned here.
The comparison to Hader is easy to see. Both are strikeout lefties who miss bats, limit hard contact and are comfortable working under pressure late in games.
The numbers even line up in one important way: from 2024 through 2026, each allowed a .209 BABIP. The split comes in command.
Hader has a 2.99 BB/9 in that span, while Vesia sits at 4.26, which is the big red flag in his profile.
Okert, by comparison, ranked 10th in fWAR at 2.4, tied with Matt Strahm. He wasn’t the same kind of strikeout weapon Vesia is, but his strike-throwing gave him a slight edge in xFIP, 3.42 to 3.45.
Vesia’s 2026 season showed both sides of the equation. He made 72 appearances, threw 58 innings and finished with a 2.64 ERA, though his 4.03 xFIP sat above the 3.57 mark he posted in 2025.
The issue again was walks. He ended the year with a career-worst 4.97 BB/9, and even though his HR/FB% dropped from 13.2 in 2025 to 5.7, the walk problems kept his xFIP from looking cleaner.
Still, the run prevention was real. Vesia finished in the 96th percentile in xERA at 2.68, the 95th in K% and the 96th in Whiff%, which backs up how effective he was at keeping hitters from doing damage.
FanGraphs’ Steamer projection has him at 58 innings again in 2027, which would keep him in the same workload range he’s carried since 2022, when he began logging at least 56 relief appearances each season. The concern is that his xFIP is projected to climb to 4.18, driven by the walk rate and the likelihood that he won’t repeat the low BABIP and 0.62 HR/9 he allowed in 2026.
Even so, the path for Houston is straightforward. If Vesia sharpens the control, he has a strong chance to settle back into the level he’s shown over the last two seasons. And for an Astros bullpen that needs dependable arms before it reaches Hader, he could come at a workable price - around $9 million per year, with some projections pointing to two years and roughly $16 million.

Astros Could Make A Jeremy Pea Decision Fans Wont Ignore
The Astros offseason already has the feel of a roster reset, and Jeremy Pea has emerged as one of the more intriguing names to watch. With a thin free-agent market at shortstop and a front office that has changed shape, new general manager Randy Flores could have more incentive to explore a deal than the club might have had in past winters.
Pea is still the kind of player who draws attention around the league, which is exactly why the possibility matters in Houston. The decision would sit at the intersection of roster need, timing and ownership influence, with Jim Cranes preferences likely part of the backdrop as the Astros weigh whether to keep building around Pea or use his value to reshape the roster in a different direction.

Yordan Alvarez Faces A Long Wait Astros Fans Can Feel
Yordan Alvarez is heading into a familiar kind of spotlight after one of the best seasons of his career, with the Astros slugger among the three finalists for American League MVP. The winner will be announced Thursday on MLB Network, and Alvarez will be in Las Vegas for the MLB Awards show, where he could wind up with more than one piece of hardware after a year in which he put up 42 home runs and 106 RBIs while leading the league in several offensive categories.
For Houston, the wait is part celebration and part suspense, because Alvarez has done everything possible to make the conversation his own. Even with the numbers on his side and the stage set for a national reveal, there is still the matter of how the voters will sort through a crowded field, leaving Astros fans to watch the awards show with one eye on the ceremony and the other on what it might mean for one of the franchise's biggest stars.

Astros Offseason Pressure Will Reveal Plenty About Their New Decision-Maker
The Astros are handing Randy Flores a major offseason test almost immediately after elevating him into the general manager chair, and the timing could hardly be more demanding. He is stepping into the role for the first time with a long to-do list, a compressed window before the current Collective Bargaining Agreement expires and the usual pressure that comes with working for an organization that expects to stay in contention.
Flores also inherits a front office dynamic that will be watched closely around the league, especially with ownership and team executives still part of the broader baseball conversation. On top of roster planning, he has to help steer the search for a new manager to replace Joe Espada, which makes this winter less about settling in and more about showing how much control he really has when the decisions start piling up.
