Oswald Peraza is slashing .421 with a .589 wOBA and three homers over the past week while striking out just 4.3% of the time — and he's sitting at 7% ownership. That's the single biggest market inefficiency on today's board, but it's far from the only one. The algorithm flagged 10 rising signals overnight, and several of these players will not be available by Monday morning. Here's your Saturday morning waiver briefing.

Today's Top Adds

Oswald Peraza (1B/2B/3B/SS, LAA) — 7% Owned

The numbers are absurd: a .589 wOBA over the last seven days, up from .368 over 30 days, with a strikeout rate that plummeted from 21.4% to 4.3%. He's walking at a 13.0% clip (up from 8.6%), hitting the ball at 92.5 mph exit velocity with a 48.0% hard-hit rate, and he has the multi-position eligibility that makes him a lineup construction dream. Ownership jumped 5% in the last week, and at 7% he's still essentially free. The 23 plate appearances across five games confirm this isn't a one-game blip. Grab him before the Sunday morning rush.

Dominic Smith (1B, ATL) — 9% Owned

Smith is riding a .456 wOBA over the past week with a .368 average, two homers, and 93.2 mph average exit velocity across 20 plate appearances. His strikeout rate ticked down to 10.0% from 10.3% over 30 days — already elite contact skills — while his 45.0% hard-hit rate backs up the power surge. Ownership spiked 7% in a week and is accelerating. Atlanta's lineup provides everyday at-bats and favorable run-scoring context. This is a move you want to make today, not tomorrow.

Casey Schmitt (1B/2B/3B, SF) — 6% Owned

Schmitt flashes the best hard-hit rate on today's board at 56.9%, paired with a declining strikeout rate (16.0%, down from 19.7% over 30 days). A .365 wOBA, .292 average, and two homers in 25 plate appearances across five games show a player making loud, consistent contact. The three-position eligibility at 6% ownership is the kind of roster flexibility advantage that wins weeks. He's risen 5% in ownership this week and will keep climbing.

Bryce Elder (SP, ATL) — 57% Owned

Elder put up a 0.00 ERA with an 11.05 K/9 in his last outing (5.7 IP), and the underlying metrics scream this is real: a 1.70 FIP with a 30.4% strikeout rate over the past week, up from 25.3% over 30 days. At 57% ownership, he's the most-rostered player on this list and shouldn't be available in competitive leagues. If he's somehow sitting on your wire, he's the top pitching add of the day.

Heliot Ramos (OF, SF) — 45% Owned

Here's a buy-low window. Ramos's ownership actually dropped 5% this past week, but the underlying data tells the opposite story. His wOBA surged from .235 over 30 days to .363 over the last seven. His strikeout rate was cut in half — from 33.3% to 15.0% — while his walk rate climbed from 6.0% to 10.0%. A 60.0% hard-hit rate is elite, and 90.9 mph exit velocity across 20 plate appearances confirms quality contact. Managers are dropping him based on the bad month; the last week says the breakout is underway. This is the contrarian add of the day.

Watch List

Paul Sewald (RP, AZ) — 59% Owned

Sewald posted a 0.00 ERA with a 12.0 K/9 and a microscopic 0.43 FIP over the past week. His K rate spiked to 44.4% from 32.4%. Ownership surged 10% — the biggest jump on today's board — so the window is closing fast. If he's available in your league, he's closer to an "Add Now" than a watch.

Reid Detmers (SP/RP, LAA) — 32% Owned

A 36.0% strikeout rate (up from 26.9%), a 0.53 FIP, and 7.0 innings pitched in the last week make Detmers one of the more intriguing arms on the wire. Ownership climbed 4% and is trending. Monitor his next start for workload confirmation — the early signal tag means we need more innings to trust the FIP fully.

Carmen Mlodzinski (SP/RP, PIT) — 6% Owned

A 2.43 FIP with 6.0 innings of rotation workload over the past week. At 6% ownership with only a 1% weekly change, the market hasn't noticed yet. If Pittsburgh keeps running him out as a starter, he becomes a deep-league add quickly.

Mark Leiter Jr. (RP, ATH) — 1% Owned

The 54.5% K rate over the past week is eye-popping — more than double his 22.4% 30-day mark — but the 10.00 ERA tells you the walks and contact damage are still a problem. This is a pure volatility play. Watch, don't add.

Ryan McMahon (3B, NYY) — 2% Owned

McMahon's wOBA jumped from .249 to .355 in a week while his strikeout rate cratered from 30.0% to 13.3%. A 52.8% hard-hit rate and 91.1 mph exit velocity over five games back it up. At 2% ownership, he's a zero-risk stash in deeper formats — particularly if the Yankees give him consistent at-bats.

Stream of the Day

No streaming-specific signals were triggered today, so we're going off the board. The closest play is Reid Detmers, who logged 7.0 innings last week with a 0.53 FIP and a 36.0% strikeout rate. If his next start lines up favorably this week, he's a strong one-start stream candidate in 10- and 12-team formats. His 32% ownership means he may still be out there, but you'll need to check your matchup before committing. Check back tomorrow for dedicated streaming picks when the weekly slate firms up.

Ownership Movers

  • Paul Sewald (59%, +10%): Fully justified. A 0.43 FIP and 44.4% K rate don't lie. The market is catching up to the stuff.
  • Dominic Smith (9%, +7%): Justified and still early. A .456 wOBA at 9% ownership means he has massive room to climb.
  • Casey Schmitt (6%, +5%): Justified by the 56.9% hard-hit rate and declining strikeouts. Multi-position eligibility accelerates these ownership curves.
  • Oswald Peraza (7%, +5%): Massively under-owned relative to the .589 wOBA and 4.3% K rate. This should be double digits by next week.
  • Reid Detmers (32%, +4%): Trending in the right direction. The 0.53 FIP warrants the move, though the early-signal caveat applies.

Quick Hits

  • Heliot Ramos's strikeout rate dropped from 33.3% to 15.0% in a single week — that's one of the sharpest approach improvements on the board, and it pairs with a league-leading 60.0% hard-hit rate among today's signals. His ownership is moving the wrong direction. Be the contrarian.
  • Bryce Elder's 1.70 FIP and 30.4% K rate make him the most trustworthy arm on today's list. At 57% ownership, he's the add that separates attentive managers from those on autopilot.
  • Oswald Peraza's 4.3% strikeout rate over the last week is the lowest among all flagged hitters — down from 21.4% over 30 days. That kind of swing is rare and suggests a mechanical or approach adjustment that's clicking.
  • Mark Leiter Jr.'s 54.5% K rate is the highest among all flagged pitchers this cycle, but a 10.00 ERA means the strikeouts are coming with damage. It's the most fascinating — and most untouchable — stat line on the wire.
  • Ryan McMahon at 2% ownership with a .355 wOBA, 52.8% hard-hit rate, and a pinstripe uniform is a deep-league lottery ticket that costs you nothing.
