## 1. Mark Vientos (NYM) vs Michael Lorenzen (RHP)

0.800 AVG, 2.200 OPS in 5 career AB | Coors Field | **2+ Hits (+181)**

*Career: 4-for-5 · .800 · 1 HR · 1 XBH · 2.200 OPS · 1 K*

Career batting average against Lorenzen: .800 in 5 AB. Vientos has the kind of pitch recognition on this arm that does not show up against the rest of the league.

Tiny sample — treat as directional, not definitive. A home run every 5 at-bats in this matchup is well above league pace. Played at Coors Field, which amplifies any offensive edge.

## 2. Bryce Harper (PHI) vs Luis Severino (RHP)

0.400 AVG, 2.100 OPS in 5 career AB | Citizens Bank Park | **1+ Hit (-262)**

*Career: 2-for-5 · .400 · 2 HR · 2 XBH · 2.100 OPS · 1 K · 1 BB*

2 HR in 5 AB is what a real H2H edge looks like. Harper has been the bat Severino cannot put away, and tonight is another swing at it.

Tiny sample — treat as directional, not definitive. The 2.100 career OPS against this pitcher backs up the rest. Played at Citizens Bank Park, a plus environment for hitters.

## 3. Jackson Merrill (SD) vs Logan Webb (RHP)

0.667 AVG, 1.555 OPS in 15 career AB | Oracle Park

*Career: 10-for-15 · .667 · 3 XBH · 1.555 OPS · 3 K · 1 BB*

A 1.555 career OPS against a single pitcher is rare — and Merrill owns it against Webb across 15 at-bats. That is run-producing dominance, not noise.

Moderate sample — a real pattern is emerging. 3 extra-base hits in 15 AB — when he connects, the ball gets out of the infield in a hurry.

## 4. Jackson Chourio (MIL) vs Andre Pallante (RHP)

0.600 AVG, 1.727 OPS in 5 career AB | Busch Stadium | **2+ Hits (+169)**

*Career: 3-for-5 · .600 · 1 XBH · 1.727 OPS · 1 K · 5 BB*

.600 is a real number when it holds up over 5 at-bats. Chourio sees something against Pallante that other hitters do not.

Tiny sample — treat as directional, not definitive. Currently listed at 2+ Hits (+169).

## 5. Chandler Simpson (TB) vs Kevin Gausman (RHP)

0.500 AVG, 1.333 OPS in 6 career AB | Tropicana Field | **2+ Hits (+182)**

*Career: 3-for-6 · .500 · 2 XBH · 1.333 OPS · 1 K*

When OPS hits 1.333 in a career H2H sample, you take it seriously. Simpson is 3-for-6 against Gausman with the kind of contact that drives runs.

Small sample, but the dominance is notable. Currently listed at 2+ Hits (+182).

## 6. Ezequiel Tovar (COL) vs Freddy Peralta (RHP)

0.417 AVG, 1.500 OPS in 12 career AB | Coors Field | **1+ Hit (-152)**

*Career: 5-for-12 · .417 · 2 HR · 3 XBH · 1.500 OPS · 3 K · 1 BB*

Tovar's slash line against Peralta translates to a 1.500 OPS over 12 AB. That is the kind of split that turns a prop into a play.

Moderate sample — a real pattern is emerging. A home run every 6 at-bats in this matchup is well above league pace. 3 extra-base hits in 12 AB — when he connects, the ball gets out of the infield in a hurry.

## 7. Ceddanne Rafaela (BOS) vs Framber Valdez (LHP)

0.571 AVG, 1.482 OPS in 7 career AB | Comerica Park | **1+ Hit (-202)**

*Career: 4-for-7 · .571 · 2 XBH · 1.482 OPS · 2 K*

When OPS hits 1.482 in a career H2H sample, you take it seriously. Rafaela is 4-for-7 against Valdez with the kind of contact that drives runs.

Small sample, but the dominance is notable. Currently listed at 1+ Hit (-202).

## 8. Dansby Swanson (CHC) vs Andrew Abbott (LHP)

0.357 AVG, 1.429 OPS in 14 career AB | Wrigley Field | **1+ Hit (-180)**

*Career: 5-for-14 · .357 · 2 HR · 4 XBH · 1.429 OPS · 2 K · 4 BB*

A 1.429 career OPS against a single pitcher is rare — and Swanson owns it against Abbott across 14 at-bats. That is run-producing dominance, not noise.

Moderate sample — a real pattern is emerging. A home run every 7 at-bats in this matchup is well above league pace. 4 extra-base hits in 14 AB — when he connects, the ball gets out of the infield in a hurry.
