MLB: T-Bone System

The T-Bone System (named after the person who came up with the original idea, although I suspect that isn't his real name) is a regular season baseball (MLB) system backing road favourites (-140 or hotter) coming off a loss, and was introduced in 2016.

Here are the results over the past nine completed seasons, updated to include the 2019 season.

Note that returns are all calculated using the US practice of risking the line to win 100 units when playing favorites, and risking 100 units to win the line when playing on underdogs.

Money Line:

Run Line:

Combined:

The probability that these returns (on straight up bets) are down to luck is estimated to be about 1 in 2,500.
