Best MLB Runs Matchups — Monday, August 3, 2026
Top runs spot: Jeremy Peña
Jeremy Peña (HOU) tops the board at 100, facing RHP Shane Bieber. The righty is scoring at .216 R/PA against righties this year — and .348 over the last two weeks, an excellent bat that turns into a run in about 17% of his trips. And Shane Bieber has been getting lit up by righties lately — .154 runs per batter faced. 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. He's owned Shane Bieber too — .333 across 3 career trips. It all sets up in a neutral park.

How to read these runs matchups
Each score (0–100) starts with the hitter's runs scored 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.
