Daily Waiver Report — Sunday, August 23, 2026

Javier Sanoja is posting a .487 wOBA over the last seven days and still sits at just 13% ownership — if you need middle-infield or outfield help down the stretch, this is the add before the window closes. Ten rising signals hit our radar overnight, headlined by two players who deserve roster spots right now and a handful of intriguing watch-list names that could become next week's must-adds.

Today's Top Adds

Javier Sanoja (2B/3B/SS/OF, MIA) — Add Now

Sanoja's bat has erupted over the past week: a .409 average, 2 home runs, and a .487 wOBA across 23 plate appearances — a massive jump from his .346 wOBA over the previous 30 days. The multi-position eligibility alone makes him a roster construction dream, and ownership has surged 7% in the last seven days to 13%. That trajectory says the secret is getting out. Five games is a solid enough sample to act on when the underlying quality indicators — not just batting average, but wOBA — are this strong. Get him before he's a 30% add next week.

Luis Robert Jr. (OF, NYM) — Add Now

Robert is flashing the five-tool ceiling again. Over the past seven days: .278 AVG, 3 home runs, and a .452 wOBA — up from .322 over 30 days. More importantly, the process is improving. His strikeout rate has dropped from 29.8% to 23.8%, while his walk rate has climbed from 7.1% to 9.5%. That's a better approach translating into better results across 21 plate appearances. At 37% rostered, he's available in more leagues than he should be. The combination of declining K-rate, rising walks, and power output is exactly the convergence of signals that precedes sustained production.

Watch List

Garrett Mitchell (OF, MIL)

A .797 wOBA demands attention even with the obvious small-sample caveats. Mitchell hit .727 with a homer this week while cutting his strikeout rate from 28.0% to 8.3%. The underlying plate discipline shift is real — the batting average will normalize, but if the K-rate stays suppressed, he's a legitimate add. Monitor the next three to four games closely.

Coby Mayo (1B/3B, BAL)

Mayo's .450 wOBA over the last week (up from .375 over 30 days) came with 2 home runs across 23 plate appearances. His strikeout rate dipped from 30.3% to 26.1% and his walk rate rose from 6.6% to 8.7%. At 3% rostered, he's essentially free. One more strong week and he moves to "Add Now."

Tim Tawa (1B/2B/3B/OF, AZ)

Tawa's strikeout rate plummeted from 22.2% to 11.5% this week while his walk rate doubled from 5.6% to 11.5%. That plate discipline overhaul powered a .304 AVG and .387 wOBA across 26 PA. Ownership is only at 10% and trending up. The multi-positional eligibility adds value.

Donovan Walton (2B/3B, ATH)

Walton is essentially unowned at 0% but posted a .449 wOBA with a .333 average and 18.2% walk rate over 22 plate appearances. A deep-league dart throw with legitimate on-base skills if the playing time holds.

Jose Fernandez (1B/3B/SS, AZ)

A .375 average and .438 wOBA through 20 PA is an early signal worth tracking. No homers yet, so this is contact-driven production. Still at 1% ownership — file away and revisit midweek.

Jake Cronenworth (1B/2B/SS, SD)

Cronenworth's wOBA jumped from .307 to .395 this week, supported by a 16.0% walk rate (up from 10.6%). The .286 average and 1 homer across 25 PA won't blow anyone away, but the on-base skills and positional flexibility at 6% ownership make him a viable add in deeper formats.

J.T. Realmuto (C, PHI)

The catcher position is a wasteland, which makes Realmuto's .412 wOBA this week notable — even without a homer. His walk rate ballooned to 20.0% (up from 9.1%), and his K-rate dipped to 20.0% from 22.7%. Ownership has actually cooled 2% to 18%, which means you might be buying low on a name-brand catcher showing improved plate discipline. If you're streaming catchers, he's worth a look over the coming week.

Gregory Soto (RP, PIT)

Soto posted a 0.00 ERA and 16.36 K/9 this week with a 42.9% strikeout rate (up from 32.8%) and a 0.37 FIP. Ownership has dipped 3% to 26%, which feels wrong given these dominance metrics. Still an early signal, but the stuff is playing up. Worth a speculative grab in leagues where saves or holds matter.

Stream of the Day

No streaming-specific signals emerged from today's data — the algorithm didn't flag any pitchers with favorable single-start matchups for the coming days. If you're looking for a short-term offensive boost, Luis Robert Jr. functions as a pseudo-stream at 37% ownership: his power surge (3 HR in the last 7 days) and improved plate discipline make him an ideal plug-and-play outfielder for Sunday lineups. Check back tomorrow for pitching streamers.

Ownership Movers

  • Javier Sanoja (MIA): 13% (+7%) — The biggest mover of the week, and fully justified. A .487 wOBA across 5 games with multi-position eligibility is the exact profile that drives waiver rushes. This train hasn't left the station yet, but it's boarding.
  • Tim Tawa (AZ): 10% (+2%) — A modest bump that undersells his week. The strikeout rate cut in half is more meaningful than the ownership curve suggests. Expect acceleration if he keeps putting up a .387 wOBA.
  • Luis Robert Jr. (NYM): 37% (stable) — Flat ownership despite a .452 wOBA week with 3 homers. The market hasn't caught up to the breakout indicators yet. That's your edge.
  • Donovan Walton (ATH): 0% — Literally nobody owns him. A .449 wOBA from the wire is the definition of free production. The risk is playing time, but the cost is zero.
  • Jose Fernandez (AZ): 1% — Ghost-level ownership for a player posting a .438 wOBA. Speculative, but the price is right.

Quick Hits

  • Garrett Mitchell's .797 wOBA is the highest seven-day mark on today's board by a wide margin. His .727 batting average will obviously regress, but the 8.3% strikeout rate (down from 28.0%) is the number to watch — if that stays below 15%, he becomes a must-add.
  • Gregory Soto's 0.37 FIP this week is elite-closer territory. A 42.9% K-rate from a reliever at 26% ownership is a market inefficiency in leagues that count strikeouts or ratios.
  • Three Arizona playersTim Tawa, Jose Fernandez, and the broader D-backs lineup — showed up in today's signals. If you're looking for stacking opportunities, Arizona's offense is quietly producing across multiple roster spots.
  • J.T. Realmuto's 20.0% walk rate this week is nearly double his 30-day mark of 9.1%. At a position starved for OBP, that's a meaningful development — especially with his ownership cooling to 18%.
  • Coby Mayo at 3% ownership with a .450 wOBA and 2 homers in the last week is the deepest sleeper on the board. Baltimore's lineup provides favorable lineup protection, and the power is legit.
