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 | **1+ Hit (minus 140)** *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'm on his hit prop tonight. ## 3. Spencer Torkelson (DET) vs Tanner Gordon (RHP) 0.600 AVG, 1.400 OPS in 5 career AB | Comerica Park *Career: 3-for-5 · .600 · 1 XBH · 1.400 OPS · 1 K* Torkelson is 3-for-5 (.600) lifetime against Gordon. He sees this pitcher well and the at bats keep coming back as hits. Tiny sample, so treat it as directional, not definitive. Bottom line: Torkelson owns this matchup against Gordon. I want him in my lineup tonight. > Look up any pitcher vs batter career history on the [Hitter vs Pitcher dashboard](/mlb/hitting-stats). ## 4.

That is run producing dominance, not noise. Moderate sample, and a real pattern is emerging. A home run every 6 at bats in this matchup is well above league pace. 4 walks in 11 AB show he reads this arm well even when he is not swinging. Verdict: give me Devers every time he steps in against King. I'm on his hit prop tonight. ## 5.
