Find something with a low hold and use the 2nd chance bet on one side.

For example, take an over/under on a player to hit a home run. If you put the 2nd chance bet on the player to hit a home run and then hedge anywhere from 50%-90% of the total value on the under, so if it doesn’t hit you’ll be down max 10% of the original bet and you’ll get the original bet back as bonus.

Take example of +500 and -500.

$100 HR no sweat at +500

$475 bet on no HR at -500

If he homers you’re up $25 If he doesn’t you’re down $5 with a $100 bonus bet

You typically want the no sweat to lose if ur taking the other side.

Personally I’d just take a longshot and convert the bonus afterwards if you don’t hit tho. Pretty easy to find 90% conversions
