Not on the current slate
Sebastián hasn't been scored in 75 days — his last matchup was against Houston Astros on Tuesday, June 9, 2026. A gap that long usually means an injury, a minor-league option, or a roster move rather than a rest day. Everything below is his most recent real production, not a projection.
Small sample, handle with care
Sebastián has just 38 at-bats in our graded season log — not enough to say much. He's hitting .289 across them, but a number built on this little data moves wildly with one good week. His confidence rating on any board reflects that: the model will still score his matchup, it's just honest that it's working with thin information. Treat the projection as a starting point, not a read.
He's a right-handed bat
Sebastián hits from the right side, so the platoon math runs the other way from a lefty's. Right-handed bats face right-handed pitching most of the time, meaning his baseline is built against the harder side and a left-handed starter is the upgrade. That's why a righty's score can jump on a day nothing else about the matchup changed. The model weighs his rates against the specific handedness he's drawing rather than a blended season number, which is where a lot of the day-to-day movement in his score comes from.
His best game in the log
Sebastián's biggest night was Sunday, June 7, 2026 at LAD — 5-for-5 with 6 driven in. That's the ceiling, not the expectation. The projection you'll see on a board is closer to his typical game than his best one, which is the whole point of projecting rather than remembering.
No graded record on him yet
We haven't ranked Sebastián a top-20 hitter matchup often enough this season to have a record worth publishing — not once so far. He's appeared in 17 graded games, so the log below is real; there just isn't a track record on our calls to show. It'll build here if the matchups start landing his way.
Where he lands across our boards
Sebastián was scored on 12 boards in that matchup, and the spread is the interesting part: hits graded 26.4/100 while walks came in at 9.4/100. 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
Take the name off Sebastián and the model still produces the same number, because it's scoring the matchup rather than the player. His splits against this handedness, what the opposing starter and bullpen actually allow, how many plate appearances he's likely to get, the park, the weather, how he's swinging lately. All of it lands on a 0–100 scale against everyone else playing today. We don't publish how it's weighted. We publish every result it produces.
What we'd flag
Three caveats worth carrying. Not every player gets a posted line — book coverage runs to about 87% for confirmed starters, so a blank line is the market's silence, not ours. Lineup changes land late enough to strand a projection published hours earlier. And judging any of this on a single night is meaningless; the model is tuned on hundreds of settled outcomes. For Sebastián specifically, his sample is small (38 at-bats logged), and we don't have a meaningful graded record on him yet.
