Bryce Harper to hit a HR — (+507, Kalshi)

PLAYER HOME RUNSATL@PHI· 2026-09-07T17:05:00Z

Bryce Harper

Over 0.5 Player Home Runs

Bet now+507

Harper is in the middle of a monster season: 27 home runs, an .891 OPS and a .501 slugging percentage. He gets Grant Holmes at home in Citizens Bank Park, one of the best parks in the league for left-handed power, and his recent batted ball is loud with a pair of 104-to-107 mph exit velocities and a home run in the sample.

At +507 the superstar lefty in a bandbox is strong value, and the price is up there simply because pitchers pitch around him. When he does get a ball to drive, it leaves.

Jackson Chourio to hit a HR — (+471, Kalshi)

PLAYER HOME RUNSCHC@MIL· 2026-09-07T18:10:00Z

Jackson Chourio

Over 0.5 Player Home Runs

Bet now+471

Chourio is a 21-homer bat with a .473 slugging percentage, and he draws the left-hander Matthew Boyd, whom the model flags to right-handed hitters with a 1.15 HR-risk mark. Boyd has been vulnerable to that side, allowing a .547 slugging percentage and a 26.3% HR/FB rate to righties.

Chourio’s power scores light up the zone chart, grading 93-to-100 in several of the areas Boyd works, and his recent contact is elite with a 97.8 mph exit velocity and a 24% barrel rate. At +471 this is a premium matchup.

Roman Anthony to hit a HR — (+707, Kalshi)

PLAYER HOME RUNSLAA@BOS· 2026-09-07T17:35:00Z

Roman Anthony

Over 0.5 Player Home Runs

Bet now+707

This is the ceiling swing. Anthony has just 3 home runs on the year, but the rookie’s batted ball keeps grading loud, with a 95 mph exit velocity, a 26.7% barrel rate and a 66.7% hard-hit rate in the sample.

He is a left-handed bat drawing Grayson Rodriguez, whom the model flags to lefties with a 0.92 HR-risk mark and a .500 slugging allowed to that side, at Fenway Park. At +707 the hot bat is a strong-priced boom leg to round out the card.

HR Prop Parlay

Combining the three legs into one home run parlay pays +27870. Odds are subject to change.
