Michael Massey Is Surging — And WaiverScout's Algorithm Just Upgraded Him
Michael Massey posted a .613 wOBA over the last seven days with a 0.0% strikeout rate, and for the first time this season, WaiverScout's algorithm has moved him off the "deprioritize" list and into Watch territory. The data is clear: something has changed.
The Signal Shift
WaiverScout flagged Massey as a deprioritize on May 6, April 28, and April 12. Every time, the underlying numbers said stay away. That call was correct — his 30-day line tells the story of a hitter who was struggling: .224 AVG, .289 wOBA, 22.2% K rate across 72 plate appearances. Not the profile you chase on waivers.
But the last five games have been a different player entirely. Massey is slashing .417 with 2 home runs and 5 RBI over his last 12 plate appearances. The wOBA has exploded from .289 over 30 days to .613 over seven. And perhaps most importantly, he hasn't struck out once in that stretch — a 0.0% K rate against a 22.2% 30-day mark. That's not a tweak. That's a mechanical reset.
The Rolling Windows Tell the Story
Here's where the nuance matters. Look at the 14-day window: .200 AVG, .279 wOBA, 21.9% K rate, 27.4% hard-hit rate. That's the cold Massey sandwiched between two versions of himself. The most recent seven days obliterate that middle stretch, but the 14-day numbers remind you how quickly he was ice cold.
The 30-day hard-hit rate sits at 43.0% — which is actually solid and higher than his 7-day mark of 41.7%. His exit velocity is steady at 90.0 mph over the last week against 89.6 mph over 30 days. These aren't dramatic Statcast jumps. The batted ball quality has been there; the results are just now catching up.
Dual Eligibility Creates Opportunity
As Yahoo Sports recently noted, Massey has embraced a dual role with the Royals, splitting time between second base and the outfield. That 2B/OF eligibility is fantasy gold on waivers — roster flexibility matters, especially in deeper formats where you need a bench bat who can slot into multiple positions.
At 0% rostered, nobody owns him. Zero percent. In a world where managers chase names like Jose Altuve or Fernando Tatis Jr. for positional overlap, Massey is sitting unclaimed while producing real counting stats — 3 home runs and a steal over the last 30 days with the hot stretch still building.
Why Watch and Not Add?
Thirty-two plate appearances over the evaluation window give us a solid sample to work with, but the surge is concentrated in just 12 PA. The 0.0% walk rate across both the 7-day and broader windows is a concern — Massey isn't drawing free passes, which means the BABIP gods need to keep cooperating. A .417 average doesn't sustain without elite plate discipline or elite contact quality, and his 90.0 mph exit velocity is competent but not elite.
The hard-hit rate at 41.7% over seven days is fine. Not dominant. The swing decisions and results are outpacing the underlying quality metrics just enough to warrant caution before a full add recommendation.
The Verdict: Watch
Michael Massey earns his first WaiverScout upgrade after three consecutive deprioritize flags. The strikeout rate collapse and wOBA explosion are real signals, backed by a 32 PA sample. The 2B/OF eligibility at 0% ownership means you have time — but not unlimited time. If the K rate stays suppressed and the hard contact holds through another week, this moves to a clear add. For now, get him on your watchlist immediately. The numbers back it up, and this window won't stay open if the production continues.
