Dylan Lee Is Quietly Becoming One of the Most Dominant Relievers in Baseball

Dylan Lee has posted a 0.00 ERA with a 15.65 K/9 over his last 2.3 innings, and his strikeout rate has surged to 50.0% in the past seven days. At just 21% rostered, this is the kind of signal that separates proactive managers from reactive ones.

WaiverScout Has Been Tracking This

We first flagged Lee back on April 19 when he was rostered in just 4% of leagues. At the time, it was a tentative watch signal — the skills were interesting but the role wasn't clear. Ownership has climbed steadily since: from 1.1% in early April to 7%, then 11%, then 18%, and now 21%. The signal has only strengthened. What started as a peripheral blip is starting to look like a legitimate reliever breakout — though we want to see more innings before fully committing.

The Rolling Numbers Tell the Story

Lee's recent performance windows paint a picture of a pitcher who's getting better, not just lucky:

  • 7-day: 0.00 ERA | 15.65 K/9 | 0.93 FIP | 2.3 IP
  • 14-day: 0.00 ERA | 15.28 K/9 | 0.84 FIP | 5.3 IP
  • 30-day: 1.59 ERA | 12.74 K/9 | 2.22 FIP | 11.3 IP

That 30-day FIP of 2.22 was already excellent. Now zoom in: a 0.93 FIP over seven days and 0.84 over 14 days suggest Lee isn't just pitching well — his underlying skills are elite-caliber right now. A 50.0% strikeout rate in the last week, up from an already strong 36.4% over 30 days, indicates a pitcher who could be emerging as a genuine weapon in Atlanta's bullpen.

The Broader Picture

As FanGraphs recently argued, Lee has been underrated for years — six consecutive major league seasons and over 200 innings pitched, yet perpetually ignored in fantasy circles. That analysis aligns with what our algorithm has been detecting: this is a pitcher with a real track record whose current numbers are supported by skills, not luck.

The confidence level here remains early signal. We're working with 11.3 innings over 30 days and just 5 games in the recent sample. That's enough to see the skills spike but not enough to project it as a new baseline. The FIP stability across windows — dropping from 2.22 to 0.84 — is encouraging, but small-sample volatility is real for relievers.

Ownership Window

At 21% rostered with a +3% gain in the last seven days, Lee is trending upward but still widely available. Compare that to relievers like Mason Miller, Devin Williams, or David Bednar — all locked in at near-universal ownership. Lee isn't in that tier yet, but if these strikeout numbers hold and he starts earning higher-leverage opportunities in Atlanta, that ownership gap closes fast.

Verdict: Watch

Don't rush to add Dylan Lee in shallow leagues, but get him on your radar immediately. Early signs suggest a pitcher whose skills are catching up to the opportunity. A 50.0% K rate and sub-1.00 FIP over the last two weeks — even in limited innings — are not nothing. If you're in a deeper league or need ratio help, he's worth a speculative add now. In standard formats, monitor for one more strong week. If the strikeout surge holds and the Braves give him more high-leverage work, this moves from Watch to must-add territory quickly. We've been watching since he was at 4% ownership. The signal keeps getting louder.
