2025 MLB Closer Carousel: Rangers' Luke Jackson Emerges as Unlikely Saves Leader | Fantasy Baseball Breakdown
Breaking down the unpredictable closer landscape in early 2025, with surprising saves leaders like Texas' Luke Jackson and key fantasy recommendations.

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
