Zach Pop Is Striking Out Nearly 40% of Batters — And Nobody Has Added Him
Zach Pop posted a 38.5% strikeout rate over the last seven days, up sharply from 28.6% over the prior 30-day window. That kind of jump in a reliever's swing-and-miss rate is exactly the type of early signal worth acting on before the rest of your league catches up — and right now, Pop sits at 0% rostered.
What the Rolling Numbers Show
The trajectory here is worth paying attention to. Over the last 14 and 30 days, Pop was sitting at a 10.8 K/9 with a 2.5 FIP across 5 innings — already strong indicators for a reliever. But the most recent seven-day window tells a sharper story: a 15.0 K/9, a 1.77 FIP, and that 38.5% strikeout rate across 3 innings of work.
Yes, we're talking about a small sample. Three innings over seven days isn't a season. But the direction of movement matters. The strikeout rate is accelerating, and the FIP is sitting in elite territory. Early signs suggest Pop is entering a stretch where his stuff is playing up.
Skills Validation
The FIP of 1.77 over the last week is the anchor here. FIP strips out defense and luck and tells you what the underlying performance looks like based on strikeouts, walks, and home runs allowed. A sub-2.00 FIP for a reliever — even in a short window — reflects genuine dominance in the things pitchers control. Combined with a K/9 of 15.0, the stuff appears to be generating swings and misses at an elevated rate right now.
The 14-day FIP of 2.50 and K/9 of 10.8 provide a useful baseline: Pop was already pitching well before this recent spike. The seven-day numbers aren't coming out of nowhere — they're an escalation of an already functional skill set.
The WaiverScout Signal History
It's worth noting that WaiverScout flagged Pop as Add Now on April 3rd, with ownership still sitting at 0%. Before that, on April 1st, the system had him classified as deprioritize — the data has since shifted, and the signal has only strengthened. This is the window. Ownership hasn't moved. The algorithm caught it early, and the numbers have followed.
Ownership Context
Zero percent rostered. Zero percent change over the last seven days. Pop is completely off the radar in most leagues, which is the opportunity. Reliever surges can move ownership fast once a save situation clarifies or a dominant stretch gets noticed on a box score. Right now, you're ahead of that curve.
If you're in a competitive league looking for bullpen depth or a speculative hold piece, this is the moment. Comparable arms at the position — like Chase Silseth and Drew Pomeranz — are worth monitoring, but Pop's current strikeout trajectory puts him in a different tier of immediate interest.
Verdict: Add Now
A 38.5% K-rate, a 1.77 FIP, and 0% ownership is not a coincidence you ignore — it's a gap you exploit. The sample is small, and early signs suggest rather than guarantee, but the underlying skills are pointing in one direction. Zach Pop is worth a waiver claim today, before the numbers force everyone else to notice.
