If you're playing in a 10-team fantasy baseball league—or anything shallower—you know the struggle: the waiver wire can feel thin, but the difference between a championship and a middle-of-the-pack finish often comes down to finding those overlooked gems. This article is your cheat sheet for exactly that.
Our regular Friday Waiver Wire column covers players rostered in fewer than 50% of Yahoo leagues, which is perfect for 12-team formats. But there's a sweet spot: players who are owned in 50-80% of leagues but still deserve a much closer look. These are the guys who can upgrade your lineup right now.
Davis Martin, SP, White Sox (80% rostered)
Let's be real—very few pitchers can sustain a 1.62 ERA over a full season, and Martin probably isn't one of them. But his recent dominance is impossible to ignore. With a 27.1% strikeout rate and a microscopic 5.2% walk rate, he's showing improved plate command that could keep his ERA around 3.00. He needs to be rostered in 90% of leagues while we figure out if this is the new normal.
Landen Roupp, SP, Giants (77% rostered)
Roupp has quietly turned into a must-roster arm thanks to improved swing-and-miss stuff. Despite an unlucky 67.9% strand rate, his 2.52 xERA actually suggests he's been better than his 3.09 ERA shows. Add in a pitcher-friendly home park and a knack for generating ground balls, and you've got a high-floor starter who's just getting started.
Braxton Ashcraft, SP/RP, Pirates (74% rostered)
Ashcraft's 2.77 ERA and 1.05 WHIP are solid—but take away one rough outing on April 28, and those numbers drop to a jaw-dropping 1.82 ERA and 0.95 WHIP. The 26-year-old brings serious heat (97.0 mph average fastball), strikes out batters at a 26.7% clip, and induces grounders like a pro (7.3% ground-ball rate). He's the definition of a reliable fantasy asset.
Ryan Weathers, SP, Yankees (67% rostered)
K-BB% is one of the best predictors of fantasy success, and Weathers ranks 10th among all qualified pitchers in that category. Playing for a Yankees team that's 26-16 and rolling, the left-hander has both the skills and the run support to deliver a high ceiling every time he takes the mound.
Kyle Harrison, SP/RP, Brewers (62% rostered)
It's surprising to see Harrison owned in only 62% of leagues. The Brewers have a knack for developing arms, and Harrison's stuff plays up in their system. If he's sitting on your waiver wire, don't overthink it—this is the kind of pitcher who can anchor your rotation down the stretch.
Whether you're chasing a playoff spot or just trying to stay competitive, these players offer the kind of value that wins leagues. Check your roster, scan the wire, and make the moves that separate contenders from the rest of the pack.
