In the evolving landscape of MLB bullpens, Justin Martinez has emerged as a strong candidate for saves with the Arizona Diamondbacks, especially in the wake of A.J. Puk's injury. However, Martinez's recent fatigue raises questions about his durability. Meanwhile, the Boston Red Sox's Aroldis Chapman remains in the driver's seat for saves even as high-leverage scenarios challenge his availability.

In Chicago, Ryan Pressly’s grip on the closer role appears secure despite recent struggles from his teammate Porter Hodge. Meanwhile, the White Sox remain a team to avoid for saves, having yet to record one this season. The Cincinnati Reds’ closer situation is murky with Emilio Pagán competing against Alexis Díaz, who has had setbacks since returning from the IL, giving Pagán an edge.

For the Cleveland Guardians, Emmanuel Clase’s struggles signal potential buy-low opportunities, while Tommy Kahnle continues to dominate the ninth inning for the Detroit Tigers despite recent heavy usage. Lastly, Devin Williams’ recent performance with the New York Yankees raises concerns, making him a player worth monitoring closely in fantasy leagues.
