Today's matchup
Bo draws Minnesota Twins at home today. He shows up on 12 boards — total bases (79.1/100, #4), h+r+rbi (77.1/100, #6), doubles (75/100, #2), runs (74.6/100, #7). We've got him at 1.7 on the total bases board. Open any board row for the full breakdown of what's driving it.
He's a left-handed bat
Bo hits from the left side, and that's the first thing the model looks at. Left-handed hitters see right-handed pitching most nights, which is the favourable side — so a lefty bat's baseline is set against righties, and drawing a left-handed starter is a genuine downgrade rather than a rounding error. When you see his score fall on a day he's still in the lineup, an opposing lefty is usually why. Handedness also shapes the park read: pull-side geometry matters more for a left-handed swing than the raw park factor suggests.
Where he lands across our boards
Bo was scored on 12 boards in that matchup, and the spread is the interesting part: total bases graded 79.1/100 while stolen bases came in at 17.7/100. Same player, same game, same opposing arm — different questions. A spread that wide usually means the matchup favours one kind of outcome over another, and it's the clearest argument for reading the board that matches what you actually care about.
How the model reads him
Bo gets scored the same way a backup infielder does — same inputs, same scale, no thumb on it. What he's done against arms of this handedness, what this particular pitcher and bullpen give up, his likely plate appearances, the ballpark, the conditions, his recent form. The weighting behind those is ours and gets re-tuned weekly against what actually happened. The output is public and graded, which is the only claim worth making.
What we'd flag
Read this page knowing what it can't do. It can't show you a line no book posted — coverage peaks around 87% for confirmed starters. It can't see a lineup change that happens after the projection publishes. And it can't tell you anything useful from one game, because the model is only measurable across a season-sized sample. For Bo specifically, we don't have a meaningful graded record on him yet.
