#3 Hurston Waldrep (ATL – RHP) vs CLE | Ace Matrix: 7.2
Component Score
Recent: Two solid MLB starts; splitter driving whiffs but leash short.

#4 Lucas Giolito (BOS – RHP) vs MIA | Ace Matrix: 7.3
Component Score
Recent: Steady stretch; CH/SL sequencing limiting damage; Ks moderate.

#1 Framber Valdez (HOU – LHP) vs BAL | Ace Matrix: 8.2
Component Score
Recent: Workhorse baseline with elite ground-ball profile; form steady coming in.
Opp Splits: BAL vs LHP league-average; righty thumpers punish mistakes but patient lineup overall.
DFS Upside: GPP Core / Cash-viable. Stability anchor that pairs well with chalk stacks.
#2 Zack Wheeler (PHI – RHP) vs WSH | Ace Matrix: 8.2
Component Score
Recent: 2025 form elite; slider command sharp; strong K floor.
Opp Splits: Nationals vs RHP: contact-first, limited power; struggle against velo+slider.
DFS Upside: GPP Core. Elite ceiling; reliable anchor.
Lineup Construction Notes
- Cash: Anchor with the top Ace and most stable Role/K blend.
- GPP: Use a lower-owned arm within 0.5 of the top Ace for leverage.
- Late Swap: If chalk fails early, pivot to leverage arms with correlated stacks.
