Last scored matchup
Zack isn't on today's slate. He was last scored 11 days ago, at home against Houston Astros on Sunday, September 27, 2026, where he landed on runs (66.2/100), fantasy points (57.5/100), h+r+rbi (54.4/100). This page refreshes with new projections as soon as he's back in a lineup.
He's swinging a hot bat
Zack is 13-for-38 (.342) over his last 10 games — well clear of his .261 season mark. Our model does lean on recent form, but it weights it against the matchup rather than chasing it: a hot bat facing a tough arm in a bad park still grades as a tough spot. Streaks like this one also end without warning, which is why the score moves on the matchup and not on the streak.
What kind of hitter he is
Zack has 22 home runs and 39 extra-base hits in 383 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 70 of 103 games he's batted in — 68% — with 28 multi-hit games among them. That's about average — most regulars land somewhere near it.
Home and away
Zack is hitting .295 at home (62-for-210) and .220 on the road (38-for-173) 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.
Against Houston Astros
Zack is 4-for-15 (.267) against Houston Astros in our log, over 4 games. Worth knowing, worth not over-reading. 15 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
Zack's biggest night was Thursday, September 24, 2026 against HOU — 2-for-3 with 2 homers, 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
We've ranked Zack a top-20 hitter matchup 22 times this season. He got a hit in 14 of them — 64%. That's the model reading him well, and it's the number we'd point to if you asked why we keep ranking him. It's also a season-sized sample on one player, which is smaller than it sounds; don't extrapolate it into a promise about tonight.
Where he lands across our boards
Zack was scored on 12 boards in that matchup, and the spread is the interesting part: runs graded 66.2/100 while triples came in at 3.5/100. 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.
