Major League Baseball Bullpen Instability Disrupts Fantasy Lineups and Team Strategies
The Cincinnati Reds, San Francisco Giants, and Houston Astros are among the franchises grappling with disrupted bullpen structures as injuries and poor outings leave save roles undefined.

Significant instability has disrupted bullpen hierarchies across multiple Major League Baseball teams, directly impacting roster management and fantasy baseball lineups. The Cincinnati Reds face a dual crisis with closer Emilio Pagan sidelined by a Grade 2 hamstring strain expected to last a month or two, while replacement Tony Santillan has struggled with declining velocity and recent poor outings.
Following a meltdown where Santillan allowed four runs on two home runs without recording an out, manager Terry Francona turned to Pierce Johnson for a save chance, suggesting a loss of trust in the right-hander. This decision has created uncertainty over who will secure the save role, with Graham Ashcraft also noted as a potential option despite not having recorded a hold since March.
In San Francisco, the Giants optioned closer Ryan Walker to the minors after he allowed seven earned runs in his last four appearances. Rookie manager Tony Vitello has since distributed saves among Caleb Kilian, Keaton Winn, Erik Miller, and Joel Peguero, with no clear frontrunner established for the late-inning duties.
The Houston Astros are managing Josh Hader's recovery by distributing saves to left-hander Bryan King, who recorded the last two saves including a two-inning effort on May 5. Manager Dusty Baker appears to be saving King for specific two-inning situations, while Bryan Abreu has looked more stable than Enyel De Los Santos in the interim.
Other teams noted include the St. Louis Cardinals, Baltimore Orioles, Oakland Athletics, San Diego Padres, Los Angeles Dodgers, Texas Rangers, and Washington Nationals, all experiencing shifts in their late-inning pitching hierarchies due to injuries, performance issues, or managerial decisions.
The Washington Nationals saw their presumed closer Gus Varland struggle in the eighth inning of a tie game after a previous appearance where he was rested. Left-hander PJ Poulin recorded the most recent save, complicating the hierarchy and leaving the team's late-inning strategy in flux.
