Kyle Higashioka: Early Plate Discipline Gains Worth Monitoring
Kyle Higashioka's wOBA has jumped from .272 over the last 30 days to .321 in his most recent 7-day window, and the underlying process is starting to look different than the veteran catcher we've been deprioritizing for weeks. This is still a tiny sample — 22 PA over 5 games — but the signals have shifted enough that WaiverScout is upgrading him from deprioritize to Watch.
What's Changed in the Rolling Windows
The headline number is the walk rate. Higashioka posted a 9.1% BB% over his last 11 PA compared to just 6.1% across his 30-day sample of 49 PA. That's a meaningful jump in selectivity for a catcher who historically swings freely. His strikeout rate has also ticked down — 27.3% over the last 7 days versus 28.6% over 30 days. Neither move is dramatic on its own, but together they suggest a hitter who could be emerging with a more disciplined approach at the plate.
The batting average hasn't followed yet — .222 over the last 7 days, .200 over 30 — but that .321 wOBA tells you he's doing damage when he connects. His May 31 game (2-for-4 with an RBI) and his May 23 homer show the power upside is still live.
Skills Validation: The Hard-Hit Spike
Here's where it gets interesting. Higashioka's hard-hit rate over the last 7 days has surged to 66.7% with an exit velocity of 93.6 mph. Compare that to his 14-day marks — 33.3% hard-hit rate, 84.8 mph EV — and the 30-day numbers of 30.3% and 85.1 mph. That's a massive quality-of-contact spike in a very small window.
The cautious read: this is 11 PA. A couple of well-struck balls can inflate hard-hit rate dramatically at this sample size. The optimistic read: when Higashioka squares the ball up, the exit velocity is legitimate. A 93.6 mph average EV over any stretch suggests real bat speed and the ability to punish mistakes.
WaiverScout Signal History
We've been tracking Higashioka since Opening Day. WaiverScout flagged him as an add now back on March 29, then moved him to watch on April 13 before downgrading to deprioritize through April, May, and as recently as May 30. This is the first upgrade in nearly two months, and it's driven entirely by the plate discipline and hard-hit data — not hope.
Ownership Window
Higashioka sits at 0% rostered with stable velocity. Nobody is picking him up. The major fantasy outlets — FantasyPros, CBS Sports, RotoWire — aren't beating the drum on him right now. That means if this trend holds for another week, you'll have a free pickup waiting. There's zero urgency to act today, which is exactly why this is a watch and not a pickup call.
If you're in deeper leagues where catcher is a wasteland — and it usually is — keep Higashioka on your radar alongside options like Dillon Dingler and Carter Jensen. He doesn't need to be on your roster yet.
Verdict: Watch
Early signs suggest Higashioka's contact quality and plate discipline are trending in the right direction, but 22 PA is not enough to act on. The 66.7% hard-hit rate and 9.1% walk rate are encouraging data points, not conclusions. Monitor his next 7-10 days of playing time. If the hard-hit rate stabilizes above 40% and the walk rate holds, this becomes a real add candidate in two-catcher and AL-only formats. For now, flag him and wait.
