Today's matchup
Today it's Houston Astros for Zack, away. He shows up on 12 boards — total bases (67.5/100, #32), runs (65.7/100, #29), h+r+rbi (65.1/100, #54), hits (61.3/100, #53). 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 in a cold stretch
Zack is 6-for-36 (.167) across his last 10 games, down from .269 on the season. Slumps this size are mostly noise at this sample — 36 at-bats is a fortnight, not a trend — and the model treats it that way, discounting the cold run rather than writing him off. If the matchup underneath is good, he'll still grade well here. That's a feature, and sometimes it's wrong.
What kind of hitter he is
Zack has 14 home runs and 26 extra-base hits in 260 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's a right-handed bat
Zack 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.
Floor and ceiling
Zack has recorded at least one hit in 51 of 71 games he's batted in — 72% — with 17 multi-hit games among them. That's about average — most regulars land somewhere near it.
Home and away
Zack is hitting .319 at home (46-for-144) and .207 on the road (24-for-116) across the season. That's a real-looking split, and it's the kind of thing that's usually part park and part noise. The model doesn't apply a blanket home-road adjustment — it prices the actual ballpark he's standing in, which is the part that carries signal.
His best game in the log
Zack's biggest night was Sunday, August 16, 2026 against TEX — 2-for-5 with 1 homer, 2 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 Zack have graded
In the 11 games where we ranked Zack a top-20 hitter matchup, he recorded a hit 7 times — 64%. 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
Zack was scored on 12 boards in that matchup, and the spread is the interesting part: total bases graded 67.5/100 while triples came in at 21.1/100. 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
Zack'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.
