Best MLB Strikeout Prop Today (May 21, 2026)
Trying to find the best MLB strikeout prop today without spending hours researching projections, matchups, recent form, and projected lineups?

That’s exactly what we do every day at FantasyLineups.
We spent the morning breaking down today’s strikeout props using our projections, matchup research, recent strikeout trends, and projected lineups — and one pitcher clearly rose to the top.
Spencer Strider OVER 5.5 Strikeouts
Spencer Strider
Spencer Strider stands out as one of the strongest strikeout targets on today’s MLB slate.
Our FantasyLineups projections have Strider finishing above six strikeouts against Miami, and the matchup still brings significant swing-and-miss upside against elite velocity and power pitching.
Miami’s projected lineup continues to show strikeout concerns against high-end right-handed arms, and Strider’s ability to generate swings and misses gives him one of the highest strikeout ceilings in baseball whenever he takes the mound.
Why we like the over:
- Strong projection edge over the current betting line
- Favorable strikeout matchup
- Atlanta enters as a favorite
- Elite swing-and-miss profile
- Upside to work deep into the game
