The Ronny Henriquez news is a gut punch. After emerging as the most impactful Miami Marlins reliever in 2025, he has been ruled out for the entire 2026 MLB season following Tommy John surgery. Finding somebody to fill his shoes is a daunting task, particularly at this stage of the offseason with many of the most accomplished free agent relievers no longer available.
That being said, perhaps it instills confidence in the Marlins front office to remember they originally acquired Henriquez as a waiver claim. Browsing the 40-man rosters of every team, I have identified three arms with many of the same attributes. While we can’t count on them getting designated for assignment like Henriquez did, they should be attainable at a very low cost.
The following pitchers each meet this criteria:
Primarily used as a reliever by their current team
Above-average fastball velocity
Multiple secondary pitches with at least 10% usage
Finished 2025 season healthy
Out of minor league options
Pre-arbitration eligible

RHP Colin Selby (Baltimore Orioles)
Major League Baseball made a rule change in recent years to prevent teams from constantly shuttling players back and forth between Triple-A and The Show. The Orioles pushed Colin Selby to the legal limit in 2025, optioning him on five separate occasions before we even reached the halfway mark of the season. A hamstring strain sidelined him throughout most of the second half.
Selby’s arsenal consists of a sinker, curveball, slider and four-seam fastball. The curve is his most intriguing weapon with massive vertical drop from his high arm slot and an average spin rate of 2,840 rpm.

Selby is still under club control for six more years and landed 64.5% of his pitches for strikes in limited action with the O’s, so it would almost certainly take a trade of some kind for the Marlins to pry him loose. Then again, Henriquez was in an identical situation last February when the Minnesota Twins surprisingly let him go.

RHP Chase Silseth (Los Angeles Angels)
Chase Silseth made the transition to full-time reliever last summer. From 2022-2024, his propensity for allowing home runs was a serious issue (19 HR in 89.0 IP). However, in 10 late-season appearances out of the Angels ‘pen, the only batter to take him deep was Nick Kurtz. No shame in that.
Silseth used to throw as many as seven different pitch types. In 2025, he simplified his approach—four-seamers and splitters to lefties, with the addition of sweepers and sinkers to righties.
Although Silseth’s upside is alluring, he had a lengthy IL stint for right elbow inflammation in 2024 and has only been tasked with pitching back-to-back days once in his professional career.

RHP Carlos Vargas (Seattle Mariners)
Carlos Vargas was already out of options entering 2025, so he spent the entire year on Seattle’s active roster (excluding one series he missed while on the paternity list). He posted a 3.97 ERA with a 16.3% strikeout rate in 77 innings pitched. He stuck around during their postseason run, too.
Leaning heavily on a high-90s sinker, Vargas is a ground ball machine (95th percentile among MLB pitchers in GB%). There were 12 ground ball double plays turned behind him, tied for the second-highest total of any reliever.

Vargas had jarring reverse platoon splits during his age-25 campaign—lefties slashed .205/.248/.341 while righties slashed .327/.404/.485. He could benefit a lot from learning a sweeper, much like Henriquez did upon being acquired by the Fish.
