The Philadelphia Phillies enter the 2026-27 offseason with a clear priority: overhauling a bullpen that collapsed in the final weeks of the regular season.
Manager Don Mattingly could count on only Alex McFarlane and Jhoan Duran with any consistency, leaving the rest of the relief corps unreliable when games mattered most.
That limitation makes another postseason push unlikely unless the front office adds proven arms this winter.
One name already connected to the Phillies is right-hander Jonathan Loaisiga.
Jim Bowden of The Athletic placed the 31-year-old at No. 39 on his ranking of the top free agents available and projected a two-year, $20 million deal.
Bowden listed Philadelphia among the more logical destinations, alongside a possible return to the Arizona Diamondbacks, the team Loaisiga pitched for in 2026.
Loaisiga posted a 2.42 ERA across 67 appearances, allowing just 56 hits and striking out 48 batters in 67 innings. Those numbers mark a strong recovery year, yet they also highlight the central question surrounding him.
Once regarded as a high-velocity prospect in the New York Yankees system, the Nicaraguan native has evolved into more of a ground-ball specialist after a series of injuries limited his durability.
He spent his first eight major-league seasons in the Bronx before joining Arizona last year. When available, he has been effective, carrying a career 3.30 ERA. Staying healthy, however, has rarely been straightforward.
His 67 appearances in 2026 stood as a clear career high; he had never previously reached 60 outings in a single season. That workload raises both optimism and caution.
On the positive side, Loaisiga demonstrated excellent command, walking only 1.7 batters per nine innings, well below his career mark of 2.7. He also kept the ball in the park, surrendering just three home runs all year.
Those traits fit the profile of a late-inning or high-leverage option who can induce weak contact without relying on overpowering stuff.
The risk, of course, is the injury history. Spending roughly $10 million annually on a pitcher who has struggled to stay on the field is no small commitment.
The Phillies learned that lesson recently with Brad Keller, who signed a comparable deal and then missed most of the 2026 season after an elbow injury.
Even so, the need for bullpen reinforcement is pressing enough that Loaisiga remains a realistic target. Some observers believe his market could settle below Bowden’s projection, which would improve the value calculation for a team seeking reliable depth without a massive long-term commitment.
Whether Philadelphia pursues him aggressively will depend on how the rest of the free-agent market develops and how the club’s medical staff assesses his durability.
For now, Loaisiga stands as one of the more intriguing, if imperfect, options available to address a clear roster weakness.
