Daily Waiver Report — Thursday, July 30, 2026

Luis Rengifo is slashing .333 with a .441 wOBA over the past week and sits at just 20% ownership — if you need middle-infield or outfield help, he's the clearest add on the board this morning. But the real intrigue in today's scan is a Watch List loaded with plate-discipline improvements and surging contact rates that could turn into adds within days. Ten signals fired overnight. Let's get into them.

Today's Top Adds

Luis Rengifo (2B, 3B, OF — SD)

Rengifo has posted a .441 wOBA across 24 plate appearances in the last seven days, anchored by a .333 average and two home runs. The multi-position eligibility (2B/3B/OF) makes him an extremely flexible roster piece. At 20% ownership, the window is still open in most leagues, but that won't last long if he strings together another week like this. Five games of data is solid enough to act on — add him now before the weekend slate locks.

Watch List

Francisco Alvarez (C — NYM)

Alvarez's .506 wOBA over the past week is eye-popping, and his walk rate has exploded to 31.2% (up from 14.9% over 30 days). Ownership is already surging — up 6% in the past week to 27% — so if you're in a league where he's still available, you may want to move this from "watch" to "add" sooner than later. The batting average (.364) and a home run round out a five-game stretch that suggests the approach changes are real. The one caveat: five games is still an early signal, so monitor whether that walk rate holds before burning priority.

Pedro Ramírez (2B, 3B — CHC)

A .471 batting average and .469 wOBA over the past week, up from .433 over 30 days. At just 3% ownership he's essentially free. No power to speak of yet (zero homers), so the value is pure on-base and batting average. Watch for whether he maintains consistent at-bats before committing a roster spot.

Vaughn Grissom (1B, 2B, 3B — LAA)

Grissom's .421 wOBA is backed by 27 plate appearances in seven days — the heaviest workload on today's Watch List. He's hitting .333 with two homers, and his walk rate has ticked up to 7.4% from 5.2%. The triple positional eligibility at corner infield spots makes him appealing, and at 2% ownership, there's zero urgency pressure from other managers. Let's see if the playing time holds through next week.

Evan Carter (OF — TEX)

Carter is flashing the elite plate discipline that made him a top prospect. His strikeout rate has dropped to 20.0% (from 22.1% over 30 days) while his walk rate has ballooned to 25.0% (up from 14.7%). The .472 wOBA and .400 average across 20 plate appearances tell a compelling story. At 3% ownership, you have time — but if the K-rate continues declining, this becomes an add quickly.

James McCann (C — AZ)

A .632 wOBA jumps off the page, even in a five-game sample. McCann is hitting .615 with a home run while cutting his strikeout rate to 14.3% (from 20.0% over 30 days) and walking at a 7.1% clip. At 0% ownership, nobody is paying attention. This is almost certainly unsustainable at these levels, but if you're desperate at catcher, he's worth monitoring for another few games.

Austin Martin (2B, OF — MIN)

Martin's underlying numbers are better than his .286 average suggests — the .414 wOBA is driven by a 27.3% walk rate paired with an 18.2% strikeout rate (down from 23.3%). The discipline is real, but five games at 1% ownership means this is a deep-league-only watch for now.

Colt Keith (1B, 2B, 3B — DET)

Keith's profile is intriguing: .348 average, .404 wOBA, strikeout rate down to 15.4% from 20.9%, walk rate up to 11.5% from 9.0%, and 26 plate appearances confirming consistent playing time. The lack of home runs keeps him in watch territory, but the plate discipline trend across a solid five-game sample is the kind of signal that precedes a breakout. At 8% ownership, he's widely available.

Dominic Canzone (OF — SEA)

Three home runs in the past week will get anyone's attention. Canzone has posted a .445 wOBA (up sharply from .334 over 30 days) with a .320 average across 25 plate appearances. The power surge is the story here. At 13% ownership, he's the most widely-rostered player on the Watch List but still available in most formats. If the power continues into the weekend, he'll graduate to an add.

Luis Lara (OF — MIL)

Lara is hitting .385 with a .471 wOBA and has cut his strikeout rate to 12.5%. The concern: ownership has actually dropped 2% in the past week despite the production, which suggests playing time may be inconsistent. The 30-day wOBA of .362 shows this is a recent spike. Deep-league stash at best until the role stabilizes.

Ownership Movers

  • Francisco Alvarez (27%, +6% 7d): The biggest mover of the day, and the data backs it up. A .506 wOBA and 31.2% walk rate justify the surge. This train is leaving the station — if he's available, don't overthink it.
  • Pedro Ramírez (3%, +2% 7d): A 2% jump at this ownership level means a handful of sharp managers are paying attention to his .469 wOBA. Still a niche add, but the trend line is pointing the right direction.
  • Vaughn Grissom (2%, +1% 7d): Barely registering on the ownership radar despite two homers and 27 PA in the last week. The gap between his production and his roster percentage is one of the biggest inefficiencies on today's board.
  • Luis Rengifo (20%): Stable ownership despite top-add-level production. The market is sleeping on a multi-position asset with a .441 wOBA. Take advantage.
  • Evan Carter (3%): Ownership flat despite a .472 wOBA and dramatically improved plate discipline. The name recognition should be driving more adds — the fact that it isn't means the window is wide open.

Quick Hits

  • James McCann's .632 wOBA is the highest on today's entire report — and he's at literally 0% ownership. The catcher position is a wasteland in most formats, making even volatile signals like this worth a look in two-catcher leagues.
  • Evan Carter's walk rate has jumped from 14.7% to 25.0% in a week. That's an elite-tier discipline number. If the approach sticks, the power will follow — he's only 24.
  • Colt Keith is quietly improving across every plate discipline metric — K-rate down 5.5 percentage points, walk rate up 2.5 points — while getting full playing time (26 PA). The Tigers infielder looks like a second-half riser.
  • Dominic Canzone has three home runs in five games after posting a .334 wOBA over the prior 30 days. That kind of power spike often regresses, but the .320 average suggests he's not just selling out for pop.
  • Today's Watch List is loaded with plate discipline improvements — six of the nine players flagged show declining strikeout rates, rising walk rates, or both. When hitters start controlling the zone in bunches like this, it often signals a second-half approach adjustment wave. Pay attention to who sustains it through the weekend.
