Week 15 Waiver Wire Spotlight
The fantasy baseball community is buzzing as Week 15 of the 2026 MLB season unfolds, and savvy owners are turning their attention to the waiver wire for hidden gems that could tip the balance of their leagues.
Among the most talked‑about catchers is Dalton Rushing of the Los Angeles Dodgers, who has stepped into the starting role after Will Smith’s injury and is delivering a scorching .444/.476/.833 line over his last five games, including two homers and a 4‑to‑2 strikeout‑to‑walk ratio.
Another name making waves is Tommy Edman, the versatile infielder who recently returned from offseason ankle surgery and has already posted a .378/.451/.556 slash with a 1.007 OPS in his first 13 appearances, proving he can still contribute at the plate and on the bases.
In the outfield, Garrett Mitchell of the Milwaukee Brewers is being positioned as a potential post‑hype breakout, having compiled a .265/.361/.452 line with 16 doubles, three triples, seven homers and six stolen bases in 75 career games, suggesting a surge in power and speed could be imminent.
Pitching Options on the Rise
The arms to watch include right‑hander Brandon Sproat of the Brewers, who has posted a 3.00 ERA and a 0.76 WHIP over his last 21 innings, showing a marked improvement since June 10.
Minnesota Twins starter Zebby Matthews has likewise turned a corner, delivering a 2.25 ERA and a 1.05 WHIP across his most recent three outings, indicating a sustainable level of dominance.
San Francisco Giants closer Caleb Kilian carries a 6.43 ERA but a 3.79 xERA, while striking out 28.1% of batters and converting 7 of 9 save opportunities, making him a high‑risk, high‑reward option for fantasy managers.
Finally, Pittsburgh Pirates reliever Mason Montgomery brings a 3.45 xERA, a .215 xBA and a ground‑ball rate above 54%, underscoring his upside as a strikeout‑heavy closer.
Stretch‑Run Implications
With the second half of the season looming, owners who lock in these emerging contributors could gain a decisive edge, especially as injury fatigue sets in and roster depth becomes a premium.
