Last scored matchup

Jonah isn't on today's slate. He was last scored 10 days ago, at home against Houston Astros on Sunday, September 27, 2026, where he landed on walks (20.7/100), doubles (15.9/100), singles (14/100). This page refreshes with new projections as soon as he's back in a lineup.

Recent form

Jonah is 5-for-32 (.156) over his last 10 games, in line with his .211 season line. No hot streak to fade, no slump to buy — the matchup is doing the work in his score, which is the normal case. The full game log is below.

What kind of hitter he is

Jonah has 13 home runs and 32 extra-base hits in 350 at-bats this season. That profile is why he grades better on the total-bases and home-run boards than his batting average alone would suggest — those boards reward damage, not just contact. Park and weather matter more for a hitter like him too, and both feed the score.

He bats from both sides

Jonah is a switch-hitter, which changes how the model reads every one of his matchups. Most hitters carry a real platoon penalty — a lefty bat facing a good lefty arm is a materially worse spot, and the score drops accordingly. Jonah takes the favourable side almost every night, so he doesn't collect that penalty. What moves his number instead is the quality of the arm rather than its handedness, and how the two sides of his own swing actually compare, which is rarely as balanced as the switch-hitter label suggests.

Floor and ceiling

Jonah has recorded at least one hit in 58 of 101 games he's batted in — 57% — with 14 multi-hit games among them. That's a boom-or-bust profile. He'll carry a game outright and then go quiet for three, so his hits-board score tends to sit below hitters with worse power and better contact.

Home and away

Jonah is hitting .232 at home (41-for-177) and .191 on the road (33-for-173) across the season. There's not much in it, which is the normal case. Home-road splits get talked about far more than they hold up.

Against Houston Astros

Jonah is 3-for-10 (.300) against Houston Astros in our log, over 3 games. Worth knowing, worth not over-reading. 10 at-bats against one club is a tiny sample, and the model treats it as a minor input next to what that pitching staff actually allows to his handedness. Batter-versus-pitcher history is the most quoted number in baseball and one of the least predictive.

His best game in the log

Jonah's biggest night was Friday, September 25, 2026 against HOU — 2-for-4 with 1 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.

How our calls on Jonah have graded

In the 13 games where we ranked Jonah a top-20 hitter matchup, he recorded a hit 8 times — 62%. That's a thin sample and we'd treat it as such. Every one of those calls was graded against the real box score, misses included.

Where he lands across our boards

Jonah was scored on 12 boards in that matchup, and the spread is the interesting part: walks graded 20.7/100 while h+r+rbi came in at 0/100. 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

Jonah's score rates the spot in front of him, not the name on the jersey. It weighs his rates against the kind of arm he's facing — handedness matters a lot — set against what that pitcher and his bullpen give up, then adjusts for expected playing time, park, weather, and recent form, normalized 0–100 across the slate. The weighting is proprietary and re-tuned weekly; the grading is public, and that's the half that proves anything.

What we'd flag

Books don't price every player — coverage tops out around 87% even for confirmed starters, so "no line" here usually means no book posted one rather than a gap in our data. Lineups change late, and an afternoon projection can be stale by first pitch. And the model is tuned across hundreds of graded outcomes, so one game tells you nothing about whether it's working.
