The midpoint of the baseball season brings with it a flurry of activity both on the field and in the front office. The upcoming trade deadline and the All‑Star break create a perfect storm for roster turnover, especially in the bullpen where the role of the closer is notoriously fluid. For fantasy managers, identifying relievers who are positioned to inherit save opportunities can provide a decisive edge in the second half of the season.
Why Closer Handcuffs Matter
Closers are often the most volatile players in a fantasy lineup, subject to injury, performance slumps, or sudden job loss. When a team’s primary closer shows signs of being moved or underperforming, the next man up can instantly become a high‑risk, high‑reward asset. This dynamic makes handcuffing the appropriate reliever a strategic move, especially when the underlying metrics suggest a strong chance of success.
Garrett Whitlock's Ascension
Boston Red Sox right‑hander Garrett Whitlock has emerged as the most likely candidate to assume the closer’s mantle for the remainder of the campaign. Over 29 innings this season he has posted a 2.48 ERA and a 1.00 WHIP, numbers that compare favorably with many established closers. His recent stretch of dominant outings suggests that the Red Sox may officially hand him the ninth‑inning responsibilities, making him a prime target for fantasy rosters seeking saves.
JoJo Romero and the Cardinals' Situation
St. Louis Cardinals reliever JoJo Romero could step into the closer role if veteran Riley O'Brien is dealt before the deadline. Romero’s mix of a high‑spin fastball and a sharp slider has already produced solid strikeout rates, and the team’s recent willingness to reshuffle its bullpen hints at an opening for him to prove his mettle in high‑leverage situations.
Will Vest and the Tigers' Bullpen
Detroit Tigers pitcher Will Vest has been nearly untouchable of late, posting a 1.86 ERA over a recent stretch that showcases his ability to shut down opposing offenses. With Kenley Jansen rumored to be on the move, Vest’s recent form positions him as a plausible candidate to inherit save opportunities, especially if the Tigers decide to accelerate their rebuild by trading away established closers.
Colorado's Hidden Option
Colorado Rockies reliever Jimmy Herget may not yet be a household name, but his underlying metrics paint a compelling picture of a future closer. A strong FIP and a high strikeout‑to‑walk ratio suggest that Herget possesses the skill set to thrive in high‑pressure innings, making him a sleeper candidate for save conversions should the Rockies decide to reshuffle their bullpen.
Mets' Late‑Blooming Weapon
New York Mets right‑hander Luke Weaver has been dominant since April 11, maintaining a 0.59 ERA and a 0.66 WHIP across a series of appearances. His recent stretch of scoreless outings demonstrates a level of control that could translate into a reliable closer role, especially if the Mets’ current closer struggles with consistency or health.
Athletics' Strikeout Specialist
Oakland Athletics reliever Hogan Harris has drawn attention for his elite strikeout upside, a trait that often correlates with closer success. While his save total remains modest, the team’s recent focus on developing young arms suggests that Harris could be given a more prominent role if the current closer underperforms or is moved.
Orioles' Back‑to‑Back Saves
Baltimore Orioles pitcher Tyler Wells has already recorded back‑to‑back saves, a feat that underscores his readiness to handle the ninth inning. His recent performances have shown improved command and a willingness to attack hitters, traits that could cement his status as the team’s primary closer moving forward.
Pirates' Young Arm
Pittsburgh Pirates prospect Mason Montgomery brings elite raw talent to the mound, with a fastball that can reach the upper 90s and a secondary slider that generates swings and misses. Though still early in his professional career, his potential to notch double‑digit saves makes him an intriguing stash for fantasy leagues that reward long‑term upside.
Diamondbacks' Returning Reliever
Arizona Diamondbacks right‑hander Justin Martinez is working his way back from Tommy John surgery, but the organization expects him to contribute 5‑7 saves upon his return. His rehabilitation progress has been steady, and if he can regain his pre‑injury velocity, Martinez could become a valuable source of late‑season saves.
Angels' Deep‑League Stash
Los Angeles Angels reliever Ben Joyce represents a deep‑league stash with the upside to slide into the closer role should the club trade away established options like Kirby Yates or Sam Bachman. While his current major‑league footprint is limited, his high‑spin rate and aggressive pitch mix suggest that he could thrive in high‑leverage situations if given the opportunity.
For fantasy managers, the key takeaway is to monitor injury reports, trade rumors, and recent performance trends to spot the next wave of closer opportunities. By targeting relievers who are already showing signs of dominance and who are positioned in volatile bullpen situations, owners can secure a competitive edge as the season hurtles toward its final stretch.
