numberFire has built comprehensive algorithms to pinpoint the bets with the highest probability of returning money, whether you are betting on the total, a line, or moneyline. For those new to numberFire, we use a five-star system to show which bets you should be targeting on any given night. Stars represent how much you should risk on a wager relative to what you would normally bet.

For example, if you would normally bet $110 to win $100 on a -110 spread wager, if we give a 3-star ranking, we suggest risking three times that amount: $330 to win $300.

Using our models as a guide, let's take a look at the best bets to make at MLB odds.

Tampa Bay Rays vs. Houston Astros

Under 8.0 (-106): 4-Star Rating out of 5

The Tampa Bay Rays and Houston Astros have now combined for three, six, and seven runs in this series, and numberFire's model expects that low-scoring trend to continue again tonight.

Of course, it doesn't hurt when you have Tyler Glasnow as one of the two pitchers taking the mound. Glasnow posted a 3.04 SIERA, 38.2% strikeout rate, and 9.2% walk rate in the regular season, and he's racked up 20 punchouts in 13.1 innings this postseason. Walks can be a problem, but it's otherwise hard to argue with those marks.

While the Astros boasted a league-best 19.8% strikeout rate versus right-handed pitching this year, they were more of an average offense in the split (102 wRC+).

Houston starter Zack Greinke is tougher to predict tonight. He produced a solid 3.72 SIERA, 24.5% strikeout rate, and 3.3% walk rate in the regular season but has now scuffled in back-to-back postseason starts. Arm soreness cropped up in the ALDS, as well, further muddying the waters.

But the good news for Greinke is that Tampa Bay struck out at a 26.4% clip versus right-handed pitching in the regular season -- only the Tigers were worse.

While Greinke's recent play could give us pause, numberFire's algorithm projects the under hitting 64.2% of the time, giving us a four-star betting value.
