Enyel De Los Santos: The Sub-1.00 FIP That Nobody Owns

Enyel De Los Santos is posting a 0.94 FIP over his last seven days — an elite skills marker that early signs suggest could be more than noise. At just 1% rostered, the Houston reliever is virtually invisible in fantasy leagues. That's exactly when WaiverScout pays attention.

The Signal Shift

Here's what caught our algorithm's eye: on April 10, WaiverScout classified De Los Santos as a deprioritize at 0% ownership. Two weeks later, the signal has flipped to Watch. The numbers explain why.

His strikeout rate has ticked up from 31.2% over 30 days to 33.3% over the last seven — a small but meaningful acceleration in an already dominant skill. Pair that with a 9.73 K/9 in his most recent 3.7 innings and a pristine 0.00 ERA in that window, and you've got a reliever who could be emerging as a legitimate high-leverage weapon in Houston's bullpen.

Rolling Window Breakdown

  • 7-day: 0.00 ERA | 9.73 K/9 | 0.94 FIP | 3.7 IP
  • 14-day: 1.34 ERA | 8.06 K/9 | 3.70 FIP | 6.7 IP
  • 30-day: 1.03 ERA | 10.34 K/9 | 2.99 FIP | 8.7 IP

The 30-day picture is arguably the most compelling: a 1.03 ERA with a 10.34 K/9 across 8.7 innings. That's not one dominant outing inflating the numbers — it's sustained production over a meaningful-for-a-reliever stretch. The FIP has also been trending sharply in the right direction, dropping from 2.99 (30-day) to 3.70 (14-day) and then cratering to 0.94 over the last week. The underlying skills are catching up to — and now surpassing — the surface results.

Save Opportunity Unlocked?

This is where it gets interesting. CBS Sports noted that De Los Santos grabbed a save Tuesday against the Rockies, striking out the only batter he faced. Houston's closer situation has long been a committee approach, and a reliever posting these kinds of skills metrics tends to earn higher-leverage opportunities. Worth monitoring whether this save was a one-off or a signal that manager Joe Espada is building trust.

Most fantasy publications haven't written a 2026 outlook for De Los Santos — RotoWire noted as much. Razzball has him ranked as the 145th relief pitcher. That ranking doesn't reflect what the last 30 days of data are showing. WaiverScout caught this trajectory before anyone else, and the signal has only strengthened.

The Caveats

We're working with 8.7 innings over 30 days. That's an early signal, not a verdict. The confidence level is low, and the sample is the kind that can evaporate with one bad outing. He's not in the same tier as established closers like Jhoan Duran or high-leverage arms like Jeff Hoffman and Paul Sewald — yet. But the K-rate and FIP combination at this level demands attention.

Verdict: Watch

Do not add Enyel De Los Santos in standard leagues right now. But put him on your watch list immediately. A 33.3% strikeout rate, a sub-1.00 seven-day FIP, and a save opportunity in Houston's bullpen is a combination worth monitoring closely. If the role expands or the Astros start funneling him ninth-inning work, the 1% ownership window slams shut fast. WaiverScout flagged him at 0% — don't wait until he's at 15% to start paying attention.
