As fantasy baseball managers scramble to fine‑tune their rosters for the crucial stretch of Week 15 in the 2026 season, the waiver wire has become a hotbed of opportunity. Injuries, unexpected breakout performances and a packed schedule have created a fertile ground for savvy pickups.
Among the hitters making noise, Tommy Edman’s return from an ankle injury has been nothing short of spectacular. In his first 51 plate appearances he is batting .378 with a .451 on‑base rate and a .556 slugging percentage, signaling a full‑speed recovery and a renewed role in the lineup.
Jake McCarthy, owned in just 40% of Yahoo leagues, has surged in June with a .326 average, a .361 OBP and a .554 slugging mark, adding 13 runs, 13 RBI, three homers and three stolen bases. His versatility in the outfield only amplifies his fantasy appeal.
Catchers are always a premium commodity, and Dalton Rushing is emerging as a two‑way asset for the Los Angeles Dodgers. Over his last five games the young backstop is posting a .444 average, a .476 OBP and a .833 slugging percentage, hinting at a potential platoon advantage.
Ryan Waldschmidt, currently plying his trade in Triple‑A, has been crushing Triple‑A pitching since June 17, batting .318 with three homers, four doubles, nine walks and nine strikeouts in 54 plate appearances. His power surge could translate into a mid‑season call‑up.
Javier Sanjoa’s recent stretch for the Miami Marlins showcases a .316 average, a .338 OBP and a .500 slugging percentage over the past month, while his eligibility at four positions adds a flexible fantasy value.
Outfield depth also benefits from Garrett Mitchell’s hot streak with the Milwaukee Brewers. He is batting .326 with a 1.024 OPS over his last 16 games, a performance that could push him into a regular starter role.
What to Watch Next
On the mound, Zebby Matthews has been a revelation for the Minnesota Twins, delivering a 2.25 ERA and a 1.05 WHIP across his last three outings, making him a tempting add for any pitching‑starved roster.
Ian Seymour’s season‑long numbers for the Tampa Bay Rays — 4.02 ERA, 3.33 xERA, 1.09 WHIP, a 9.1% walk rate and a 26.1% strikeout rate — suggest a pitcher who is both efficient and capable of missing bats, traits that fantasy owners love.
Brandon Sproat, also a Brewers arm, has posted a 3.00 ERA and a 0.76 WHIP over his last 21 innings, indicating a high‑leveraged reliever who could lock down late‑game situations.
Finally, Kade Anderson is dominating the minor leagues and is on the cusp of a Triple‑A promotion, a move that could herald a rapid ascent to the majors and a sudden influx of strikeouts and wins.
