Best MLB Singles Matchups — Monday, August 3, 2026
Top singles spot: Luis Arraez
Luis Arraez (SF) tops the board at 100, facing RHP the starter. The lefty is lining singles at .222 1B/PA against righties this year — and .269 over the last two weeks, an elite bat that turns into a single in about 21% of his trips. And the starter has been thin against righties lately. The bullpen behind him is roughly average to that side. He's hitting in a spot worth about 4.7 trips, so the volume's there. No real history against the starter. It all sets up in a neutral park.
The rest of the top of the board
- Yandy Díaz (TB) (92) vs RHP Michael Lorenzen: a strong bat at .165 into an arm getting picked apart by the same side (.333).
- Jeremy Peña (HOU) (92) vs RHP Shane Bieber: an elite bat at .194 into an arm tough to string hits off the same side (.056), hot bat.
- Luis Rengifo (SD) (90) vs RHP Brandon Pfaadt: an excellent bat at .174 into an arm getting picked apart by the same side (.227).
- Chandler Simpson (TB) (86) vs RHP Michael Lorenzen: an elite bat at .207 into an arm getting picked apart by the same side (.208).
- Jake Mangum (PIT) (79) vs RHP Brandon Sproat: an elite bat at .193 into an arm prone to base hits from the same side (.154).
- Nick Gonzales (PIT) (74) vs RHP Brandon Sproat: an elite bat at .209 into an arm prone to base hits from the same side (.150), due to bounce back.
- Jonathan Aranda (TB) (70) vs RHP Michael Lorenzen: a strong bat at .159 into an arm getting picked apart by the same side (.208).

Lineup watch
144 of today's hitters are still on projected lineups, drawn from each team's last game. Batting order drives the score, so these flip the moment official lineups post — usually about two hours before first pitch. Anyone who doesn't make the official card gets flagged "Not starting" and drops to the bottom.
How to read these singles matchups
Each score (0–100) starts with the hitter's singles per plate appearance against the hand he's facing — weighted toward the last two weeks, then the season, then a two-year baseline. Then it layers in the bullpen, his spot in the order, and park and weather. Higher means more of it points his way. It's context, not a lock — a great spot still goes 0-for-4 sometimes, and a tough one runs into one. The edge is in stacking the odds, and since we grade every board, you can see how often the top of the list delivers.
