Week 15 Fantasy Baseball Risers and Fallers
Week 15 of the 2026 fantasy baseball season has produced a clear split between hot and cold hitters, offering both opportunities and warnings for roster moves.
Risers Making Waves
Otto Lopez has been a revelation, slashing .462/.500/.885 over the past week with two home runs and a stolen base, a production level that places him among the most valuable short‑term assets.
Heriberto Hernandez, also a Marlin, is riding a .389/.500/1.167 line with four homers in just 22 plate appearances, a burst of power that could reshape his role in the lineup.
Cole Carrigg of the Colorado Rockies continues to hit .360/.407/.760, adding a single homer in 27 trips and showing a disciplined approach that keeps his average afloat.
Fallers Slumping
Braden Montgomery is stuck at .158/.200/.158 with zero homers in the last seven days, a stark contrast to his earlier promise.
Cody Bellinger has posted a .172/.200/.207 line with no homers and no steals in 30 plate appearances, leaving fantasy owners questioning his upside.
Jazz Chisholm Jr. is similarly underperforming, sitting at .167/.273/.167 with no homers or steals in 22 appearances, a slump that may prompt a lineup reshuffle.
The divergent trajectories highlight how quickly a player’s fantasy value can shift, urging managers to monitor recent splits and consider roster adjustments before the next series.
