MLB Betting Guide: Friday 8/21/20

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 FanDuel Sportsbook.

Boston Red Sox at Baltimore Orioles

Orioles +1.5 (-156): 2-Star Rating out of 5

numberFire's model liked the Baltimore Orioles last night, and while they ultimately lost to the Boston Red Sox by six runs, it was a tight game until a four-run ninth inning.

The algorithm sides with Baltimore again tonight, as they're in a good spot to plate some runs against the duo of Colten Brewer and Darwinzon Hernandez.

Brewer has been thoroughly mediocre over 14.0 innings with a 4.49 SIERA, most notably owning a lackluster 12.1% walk rate. He also struggled with walks in 2019 (13.4%).

Hernandez is making his 2020 debut, and while he's adept at missing bats, he similarly had control issues last season (17.7% walk rate). It wouldn't be surprising to see either or both pitchers run into trouble.

The main issue for the Orioles is whether or not left-hander John Means can keep the Red Sox off the board. Means managed a 3.60 ERA last year, but his peripherals were mediocre at best, and he's performed poorly across three starts. The good news is he's seen a notable jump in velocity, so there's a chance he can right the ship sooner rather than later.

Our projections sees the Orioles runline succeeding at a 66.17% clip, which rates as a two-star bet.

Chicago White Sox at Chicago Cubs

Under 9.5 (-106): 1-Star Rating out of 5

Our model likes the Chicago Cubs runline and moneyline tonight, but I'm a little reluctant to go there considering how well the Chicago White Sox perform against left-handed pitchers (124 wRC+ dating back to 2019), and Jon Lester isn't the pitcher he once was.

However, this could still be a lower-scoring game overall, as both Dallas Keuchel and Lester have some positives going for them.

Keuchel may only have a 13.6% strikeout rate, but his 58.3% ground-ball rate remains elite, so perhaps his 3.07 ERA isn't a total fluke. He's also allowing batted balls of 95 mph or higher at just a 32.3% rate, so it's no wonder he's only given up two home runs in five starts.

Lester's 2.74 ERA is definitely more shaky -- he also has a 5.02 SIERA -- but he's also finding a way to induce poorly hit balls. He has a solid 18.1% soft-hit rate, and much like Keuchel, he isn't giving up 95-plus mph balls often (31.9%).

I wouldn't expect either pitcher to be perfect tonight, but both may be able to avoid the long ball and keep the overall runs down. numberFire's algorithm gives the under a 52.66% chance of hitting for a one-star play.
