Top Waiver Wire Adds: July 27th, 2026

The trade deadline is days away, rosters are shifting, and your waiver wire is about to get a lot more interesting. But don't wait — these four names are already worth your FAAB right now.

Cooper Pratt

If Pratt is sitting on your waiver wire, you're leaving production on the table. He's been one of the better waiver surprises this second half, and the counting stats are backing it up — he's contributing across multiple categories, not just padding one.

The underlying numbers are what make this more than a hot-streak chase. His hard-hit rate and barrel rate both sit above league average, which tells you the contact quality is real. He's not surviving on soft singles or infield hits. When he makes contact, he's doing damage, and that tends to hold up better over a longer sample than average-driven production.

His walk rate is also quietly solid — he's not giving away at-bats, and his strikeout rate is manageable enough that you're not going to get burned by a sudden 0-for-20 spiral. The plate discipline profile is the kind that ages well as a season goes on, because pitchers can't just start throwing him chase stuff and expect results.

The opportunity looks locked in, and he's getting consistent at-bats. Guys who only play four days a week don't move the needle. Pratt is playing.

If you're in a deeper league, he should already be on your roster. In a 12-teamer, he's at least a pickup to stash and see how the next two weeks shake out.

Gabriel Moreno

Moreno's been a fantasy frustration for two years — the talent was always there, the health and playing time never cooperated. But he's in the lineup consistently enough to matter right now, and the underlying numbers are starting to back up what scouts always said about his bat.

His xBA has been running meaningfully higher than the league average for catchers, which matters because it means the hits aren't fluky. He's making real contact, and his strikeout rate is low for a catcher — that's actually a big deal. Most backstops with pop run strikeout rates that make you nervous. Moreno doesn't. His contact rate keeps his floor high, and when a catcher has a floor, that's a genuinely rare thing.

The power has shown up in flashes too, and his hard-hit rate supports the idea that there's more coming. He's not a 25-homer guy, but 12-15 with a real average at the position? That's a top-10 fantasy catcher, maybe better depending on how the second half goes.

Catcher is a wasteland in most leagues. You're probably starting someone you hate every week. Moreno gives you a real bat at the position, and the Statcast profile suggests he can sustain it — this isn't just a guy running hot on soft contact.

Don't overthink it. If he's available, add him.

Hao-Yu Lee

Lee has been quietly solid for Detroit this season. Through 64 games, he's hitting .274 with 6 homers, 23 RBI, and a .750 OPS. That's useful. A .441 slugging percentage at 23 years old in your first real MLB run is a good sign.

The Statcast profile gives you a reason to pause, though. His xBA sits at .238 and his xSLG at .401, which means he's outperforming his expected numbers. His hard-hit rate of 38.8% isn't bad, but it's not elite either. The barrel rate of 8.4% is fine.

So what's the read? He's probably not a .274 hitter going forward — the underlying numbers suggest something closer to the low .240s is more realistic. But the power is showing up for real, and the opportunity is locked in. Detroit is playing him every day, and that matters.

In shallower leagues, he's a streaming option. In 12-teamers or deeper, he's worth a longer-term stash at second base. Just don't expect the average to hold.

Roki Sasaki

Sasaki has been on a run lately, and the numbers are starting to explain why — because this doesn't look like a random hot stretch.

The stuff was never the question. The splitter plays at any level, and his fastball command has been noticeably sharper. But here's the stat that matters most right now: his walk rate has dropped significantly over his recent stretch. Early in the year he was running a walk rate that would make any fantasy manager nervous, because when Sasaki falls behind in counts he has to come over the plate with something hittable, and big-league hitters don't miss those. That's been happening less.

His chase rate numbers are improving too — hitters are still swinging at his splitter out of the zone, but Sasaki is doing a better job of setting it up. The whiff rate on the splitter has always been elite-level. The issue was he wasn't getting to his put-away pitch often enough because of count leverage. When he's ahead in counts, that pitch is basically unfair.

The strikeout rate was always going to be there. A K rate above 27% in his recent starts is right in line with what the pure stuff profile projects. What's changed is the ratios around it — the ERA and WHIP have cleaned up because the free passes are down. That's the two-category asset unlock that makes him genuinely startable, not just a K-upside dart throw.

Some people are still sleeping on him because of the early-season inconsistency. That's your window. Buy before a two- or three-start stretch reminds everyone how good he can be, because by then he won't be on your waiver wire anymore.

---

Prioritize Moreno if catcher is a problem spot. Grab Lee if second base is thin. And if you're chasing Ks down the stretch, Sasaki is the move — especially if the command adjustment holds.
