As Week 15 of the 2026 fantasy baseball season unfolds, streaming starters has become a decisive edge for many league owners. With rosters tightening and the trade deadline looming, the waiver wire offers a fresh pool of undervalued arms that can swing matchups in your favor.
Shallow‑League Gems
Jake Bennett of the Boston Red Sox has posted a 3.10 ERA and a 0.98 WHIP while fanning 31 batters over 40 innings, making him a prime target for leagues that keep rosters under 40 percent ownership. Andre Pallante of the St. Louis Cardinals sits at a 3.60 ERA and a 1.22 WHIP, having already secured ten wins in 17 starts. Walbert Urena of the Los Angeles Angels boasts a 3.03 ERA and 75 strikeouts in 77 frames, while Ian Seymour of the Tampa Bay Rays has been dominant in his last five outings, posting a 2.52 ERA, a 0.76 WHIP and 27 strikeouts in 25 innings. Cade Cavalli of the Washington Nationals rounds out the group with five wins, a 3.69 ERA and 102 strikeouts in 90 innings.
Deep‑League Options
In deeper formats, a handful of arms are beginning to separate themselves. Brandon Sproat of the Milwaukee Brewers has struck out 17 batters across his last two starts, showcasing a high‑velocity arsenal that could translate into a breakout performance. Shane Drohan, also with the Brewers, carries a 3.12 ERA and a 1.23 WHIP, having logged 59 strikeouts in 57 innings. Kumar Rocker of the Texas Rangers has compiled a 3.02 ERA and a 1.22 WHIP over his last nine starts, striking out 43 batters in 47 innings. Noah Schultz of the Chicago White Sox demonstrated his upside by fanning seven hitters in just over four innings last week, while Dean Kremer of the Baltimore Orioles has posted a 3.18 ERA, a 0.88 WHIP and 20 strikeouts in his past three starts.
With these options spread across both shallow and deep leagues, owners can fine‑tune their rotations to match weekly matchups, and the depth of talent available this week suggests that the waiver wire will continue to be a fertile hunting ground for savvy fantasy managers.
