As we head into another weekend of fantasy baseball, the streaming pool is a little thinner than usual. Fewer soft matchups, more top-end arms taking the mound. That means finding value requires a sharper eye, especially in deeper leagues. Here are a few of our favorite fantasy baseball waiver wire pickups.

Fantasy Baseball Waiver Wire Pickups: Streamers & Sleepers
This week’s focus is on mid-rotation starters trending up, plus a couple of widely available hitters who can give you a short-term boost. If you’re chasing wins, strikeouts, or just trying to squeeze out a category edge, these are the names worth your attention.
Jeffrey Springs (SP – Athletics)
Springs is quickly becoming one of the better under-the-radar arms to trust in fantasy lineups.
Through his early starts, he’s been dominant across the board. The ERA sits low, the WHIP is clean, and the strikeouts are trending back up. More importantly, the underlying profile checks out. He’s limiting hard contact, and every pitch in his arsenal is generating poor results from opposing hitters.
The changeup, in particular, looks like a true weapon again. It’s generating whiffs at a high rate, which is a big reason why his strikeout percentage has rebounded.
The matchup against the White Sox only adds to the appeal. Chicago has struggled with swing-and-miss issues and inconsistent lineup construction, making this a prime spot for Springs to deliver another strong outing.
He’s not universally rostered, especially in shallower formats, which makes him one of the best “plug and play” starters this weekend.
Reid Detmers (SP – Los Angeles Angels)
Detmers is one of the more intriguing early-season risers, and this might finally be the breakout fantasy managers have been waiting for.
The numbers tell a compelling story. A WHIP under 1.00, strong strikeout totals, and improved command with very few walks. He’s also coming off back-to-back quality starts, which suggests this isn’t just a one-game spike.
The matchup against San Diego is tougher on paper, but there are reasons to stay in. The Angels’ offense is clicking, which increases his chances of run support and a win. When you combine that with his current form, Detmers becomes a viable start even in a less-than-ideal matchup.
For managers who have been holding or watching from afar, this is the type of spot where you lean in and trust the trend.
Dean Kremer (SP – Baltimore Orioles)
Kremer fits the classic streaming profile. Low roster percentage, favorable matchup, and just enough upside to help you in multiple categories.
His first outing of the season showed flashes, especially with the strikeouts. While he’s not typically known as a high-K arm, he can generate enough swing-and-miss to be useful when the matchup is right.
Facing Cleveland, the key is avoiding damage from the middle of the order. If he can navigate that, a line in the range of five innings with modest strikeouts and limited damage is well within reach.
That may not win you the week outright, but it can stabilize ratios and give you a shot at a win.
Joey Cantillo (SP – Cleveland Guardians)
Cantillo is one of the more interesting deeper-league streamers because there’s real strikeout upside here.
He’s hovering near a 30% strikeout rate early on, and while the walks can be an issue, the swing-and-miss ability is legit. He’s also shown progression with each start, going deeper into games and improving his overall command.
The matchup against Baltimore is not without risk, but there’s enough swing-and-miss in that lineup to make Cantillo a worthwhile gamble. His fastball and changeup combination has been effective, and he hasn’t allowed more than two earned runs in a start so far.
If you’re chasing strikeouts, Cantillo might be the best upside play among widely available pitchers.
Carlos Cortes (LF – Athletics)
Cortes is the type of short-term pickup that can help you survive a weekend.
With Brent Rooker sidelined, Cortes has stepped into a larger role and made the most of it. He’s widely available across formats, especially in deeper leagues, and he’s stepping into a favorable matchup against a struggling pitching staff.
The key here is opportunity. He’s getting at-bats, and in deeper formats, that alone can be valuable. Add in a soft opponent and the potential for middle relief exposure, and you have a sneaky source of runs and RBI.
Just understand this is likely a temporary play tied to playing time.
Oswald Peraza (3B – Los Angeles Angels)
Peraza is one of the hotter under-the-radar hitters right now, and the recent production is hard to ignore.
Over the past week, he’s flashed power and speed with multiple home runs and stolen bases. More importantly, the plate discipline has improved. He’s walking more, striking out less, and making significantly better contact.
There are also tangible changes in his approach. A higher launch angle, more pulled contact, and increased barrel rates all point to a hitter making adjustments that could stick.
He’s still barely rostered in most leagues, which makes him an ideal speculative add if you need a spark in your lineup.
