2025 MLB Closer Carousel: Rangers' Luke Jackson Emerges as Unlikely Saves Leader

Texas Rangers' Bullpen Surprise

The Texas Rangers' closer situation has delivered the first major fantasy baseball shock of 2025. While veterans Chris Martin (RHP) and Robert Garcia (LHP) were projected to handle ninth-inning duties, journeyman Luke Jackson has emerged as Bruce Bochy's trusted option early on.

Why Jackson's Success Isn't Fluky

18-save pedigree: Jackson recorded 18 saves for Atlanta in 2019
Spring training dominance: 6 scoreless innings with 9 Ks this spring
Recent form: 5 saves in last 5 appearances after rocky opener
Veteran savvy: At 33, possesses more closing experience than Martin

The real fantasy value play? Jackson remains available in 42% of ESPN leagues while Martin continues to be over-rostered.

Bullpen Stock Watch

Rising Stars

1. Dennis Santana (Pirates)

Taking over for demoted closer David Bednar
Showed composure against Yankees' heart of lineup
Pirates' lack of alternatives suggests prolonged opportunity

2. Tommy Kahnle (Tigers)

Perfect through 4 appearances (0 hits, 0 walks)
Detroit's committee approach favors his experience
AL Central weak offenses create more save chances

3. Aroldis Chapman (Red Sox)

Only pitcher with multiple wins + saves
Liam Hendriks' injury opens extended opportunity
Still possesses elite swing-and-miss stuff (14.7% swinging-strike rate)

Falling Veterans

1. Emmanuel Clase (Guardians)

Velocity unchanged but command shaky early
Allowed 3 ER after surrendering just 5 all last season
Still Cleveland's closer but dynasty owners should worry

2. Ryan Pressly (Cubs)

Fastball velocity down 1.7 mph from 2024
Curveball isn't producing whiffs (4.2% swinging-strike rate)
Porter Hodge lurking as potential replacement

3. Jordan Romano (Phillies)

Velocity dip (94.7 mph fastball) concerning
Phillies' historical closer rotation continues
Jose Alvarado the better short-term play

Strategic Waiver Wire Advice

Prioritize opportunity over reputation: Jackson over Martin
Stash potential closers early: Seth Halvorsen (Rockies) showing promise
Monitor injury returns: Alexis Diaz (Reds) nearing activation
Avoid committee situations: White Sox bullpen offers no value
Trade high on surprising starters: Consider dealing Clase while name value remains
