1. Tyler Stephenson (CIN) vs Kyle Harrison (LHP)
0.600 AVG, 2.400 OPS in 5 career AB | American Family Field | 1+ Hit (minus 150)
Career: 3-for-5 · .600 · 2 HR · 2 XBH · 2.400 OPS · 1 K
2 HR in 5 AB is what a real H2H edge looks like. Stephenson has been the bat Harrison cannot put away, and tonight is another swing at it.
Tiny sample, so treat it as directional, not definitive. The 2.400 career OPS against this pitcher backs up the rest. Currently listed at 1+ Hit (minus 150).
Verdict: give me Stephenson every time he steps in against Harrison. I'm on his hit prop tonight.
2. Mark Vientos (NYM) vs Gerrit Cole (RHP)
0.429 AVG, 1.715 OPS in 7 career AB | Yankee Stadium
Career: 3-for-7 · .429 · 2 HR · 2 XBH · 1.715 OPS · 1 K
A 1.715 career OPS against a single pitcher is rare, and Vientos owns it against Cole across 7 at bats. That is run producing dominance, not noise.
Small sample, but the dominance is notable. A home run every 4 at bats in this matchup is well above league pace. Played at Yankee Stadium, with its short right field porch.
The take is simple. History sides hard with Vientos here. I want him in my lineup tonight.
3. Brayan Rocchio (CLE) vs Connor Prielipp (LHP)
0.400 AVG, 1.400 OPS in 5 career AB | Target Field | 1+ Hit (minus 187)

Rocchio is 2-for-5 (.400) lifetime against Prielipp. He sees this pitcher well and the at bats keep coming back as hits.
Tiny sample, so treat it as directional, not definitive. A home run every 5 at bats in this matchup is well above league pace. Currently listed at 1+ Hit (minus 187).
Bottom line: Rocchio owns this matchup against Prielipp. I'm on his hit prop tonight.

Career: 5-for-11 · .455 · 2 HR · 2 XBH · 1.600 OPS · 3 K · 4 BB
A 1.600 career OPS against a single pitcher is rare, and Devers owns it against King across 11 at bats. That is run producing dominance, not noise.

Verdict: give me Devers every time he steps in against King. I'm on his hit prop tonight.
6. Esteury Ruiz (MIA) vs Tyler Glasnow (RHP)
0.400 AVG, 1.400 OPS in 5 career AB | loanDepot park
Career: 2-for-5 · .400 · 1 HR · 1 XBH · 1.400 OPS · 1 K
Career batting average against Glasnow: .400 in 5 AB. Ruiz has the kind of pitch recognition on this arm that does not show up against the rest of the league.

Verdict: give me Ruiz every time he steps in against Glasnow. I want him in my lineup tonight.

Springer's slash line against Bradish translates to a 1.255 OPS over 20 AB. That is the kind of split that turns a prop into a play.
