Best MLB Singles Matchups — Friday, September 18, 2026
Top singles spot: Nathan Lukes
Nathan Lukes (TOR) tops the board at 100, facing RHP Kumar Rocker. The lefty is lining singles at .208 1B/PA against righties this year — and .282 over the last two weeks, an elite bat that turns into a single in about 20% of his trips. And Kumar Rocker has been prone to base hits from righties lately — .154 singles per batter faced. The bullpen behind him is roughly average to that side. He's hitting in a spot worth about 4.5 trips, so the volume's there. He's just .200 in 5 career PA against Kumar Rocker, but that's a tiny sample and the matchup says regression. It all sets up in a neutral park.

Lineup watch
270 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.
