Okert Is a Free Agent, and the Astros Need a Left-Handed Arm for the Late Innings — One Analysis Points to Alex Vesia
Steven Okert's two Houston seasons ended in free agency, and he took some of the bullpen's most reliable left-handed numbers with him. An SI analysis of the market says the closest available match is a Dodger with elite stuff and one loud flaw: the walks.
The Astros' winter list has a specific hole in it, and it is shaped like Steven Okert. The left-handed reliever became a free agent after two seasons in Houston — 136 appearances and a combined 2.8 fWAR — and his 2026 was the steadiest work of his career: the lowest walk rate (1.86 per nine innings), the lowest batting average on balls in play allowed (.226) and the highest strand rate (86.5 percent) he has ever posted, with his home-run rate cut down since arriving in Houston, according to an analysis published Monday by Houston Astros on SI.
The in-house alternatives explain why the hole matters. The same analysis describes the Astros' other left-handers, Bennett Sousa and Bryan King, as often inconsistent — which is how a specialist's departure becomes a market problem. The name the analysis lands on is Alex Vesia, the Dodgers left-hander who has spent six seasons in Los Angeles and pitched on the club's back-to-back World Series winners in 2024 and 2025. Over the last three seasons, among qualified left-handed pitchers, Vesia ranks fifth in fWAR at 3.3 — just behind the Astros' own closer, Josh Hader.
Vesia's 2026 line is a study in both directions: 72 appearances, 58 innings, a 2.64 ERA, a 96th-percentile expected ERA of 2.68 and a 95th-percentile strikeout rate — and a walk rate of 4.97 per nine, the highest of his career, which dragged his expected fielding-independent numbers the wrong way. FanGraphs' Steamer projections, cited in the analysis, have him working 58 innings again in 2027, the workload he has carried at 56-plus appearances every year since 2022. The price tag in the projections runs to about a $9 million average annual salary, with some estimates leaning toward two years and roughly $16 million.
Nothing about this is a move — no signing, offer or negotiation has been reported, and the Astros have made no announcement. It is a fit argument, made in the open, on the first week of the market: Houston needs a left-hander who can hold the innings before Hader, Okert's departure took exactly that pitcher out of the building, and Vesia is the available arm whose dominance numbers sit closest to the job description — provided a team believes it can fix the walks. Whether Houston is that team is the offseason question this file opens, not answers.
