Alec Burleson (STL) vs Brady Singer (RHP) 0.556 AVG, 1.944 OPS in 9 career AB | Great American Ball Park | **1+ Hit (minus 248)** *Career: 5-for-9 · .556 · 2 HR · 4 XBH · 1.944 OPS · 1 K* A 1.944 career OPS against a single pitcher is rare, and Burleson owns it against Singer across 9 at bats. That is run producing dominance, not noise. Small sample, but the dominance is notable. A home run every 5 at bats in this matchup is well above league pace. Only 1 strikeout in 9 AB shows the eye is dialed in here. The take is simple. History sides hard with Burleson here. I'm on his hit prop tonight. ## 2. Yainer Diaz (HOU) vs Grayson Rodriguez (RHP) 0.400 AVG, 1.500 OPS in 5 career AB | Daikin Park *Career: 2-for-5 · .400 · 1 HR · 1 XBH · 1.500 OPS · 1 BB* Career batting average against Rodriguez: .400 in 5 AB. Diaz has the kind of pitch recognition on this arm that does not show up against the rest of the league. Tiny sample, so treat it as directional, not definitive. A home run every 5 at bats in this matchup is well above league pace. Verdict: give me Diaz every time he steps in against Rodriguez. I want him in my lineup tonight. ## 3. Masyn Winn (STL) vs Brady Singer (RHP) 0.333 AVG, 1.500 OPS in 6 career AB | Great American Ball Park | **1+ Hit (minus 165)** *Career: 2-for-6 · .333 · 1 HR · 2 XBH · 1.500 OPS · 1 K · 2 BB* When OPS hits 1.500 in a career H2H sample, you take it seriously. Winn is 2-for-6 against Singer with the kind of contact that drives runs. Small sample, but the dominance is notable. A home run every 6 at bats in this matchup is well above league pace. Played at Great American Ball Park, a hitter friendly environment. Bottom line: Winn owns this matchup against Singer. I'm on his hit prop tonight. > Look up any pitcher vs batter career history on the [Hitter vs Pitcher dashboard](/mlb/hitting-stats). ## 4. George Springer (TOR) vs Ian Seymour (LHP) 0.556 AVG, 1.267 OPS in 9 career AB | Tropicana Field | **1+ Hit (minus 173)** *Career: 5-for-9 · .556 · 1 XBH · 1.267 OPS · 1 K · 1 BB* A 1.267 career OPS against a single pitcher is rare, and Springer owns it against Seymour across 9 at bats. That is run producing dominance, not noise. Small sample, but the dominance is notable. Only 1 strikeout in 9 AB shows the eye is dialed in here. Currently listed at 1+ Hit (minus 173). The take is simple. History sides hard with Springer here. I'm on his hit prop tonight. ## 5. Alejandro Kirk (TOR) vs Ian Seymour (LHP) 0.286 AVG, 1.107 OPS in 7 career AB | Tropicana Field | **1+ Hit (minus 207)** *Career: 2-for-7 · .286 · 1 HR · 2 XBH · 1.107 OPS · 1 K* Kirk's slash line against Seymour translates to a 1.107 OPS over 7 AB. That is the kind of split that turns a prop into a play. Small sample, but the dominance is notable. A home run every 7 at bats in this matchup is well above league pace. Currently listed at 1+ Hit (minus 207). The take is simple. History sides hard with Kirk here. I'm on his hit prop tonight. ## 6. Jonathan Aranda (TB) vs Shane Bieber (RHP) 0.200 AVG, 1.000 OPS in 5 career AB | Tropicana Field | **1+ Hit (minus 260)** *Career: 1-for-5 · .200 · 1 HR · 1 XBH · 1.000 OPS* Career batting average against Bieber: .200 in 5 AB.

I want him in my lineup tonight. ## 8. Ben Rice (NYY) vs Kyle Bradish (RHP) 0.400 AVG, 1.155 OPS in 10 career AB | Oriole Park at Camden Yards *Career: 4-for-10 · .400 · 1 HR · 1 XBH · 1.155 OPS · 3 K · 1 BB* Rice's slash line against Bradish translates to a 1.155 OPS over 10 AB.
