The Seattle Mariners can make it four straight wins if they can complete the series sweep over the Chicago White Sox this afternoon, and my White Sox vs. Mariners prediction breaks down why they'll do just that. The action at T-Mobile Park in Seattle is slated to get underway with a 4:10 p.m. ET (MLBN) first pitch.

Seattle is a massive -290 moneyline betting favorite with an O/U of 7.5 runs across our best sports betting sites, and we found value in a player prop with its high implied team total to round out our White Sox vs. Mariners best bets.

It may seem risky to lay the 1.5 runs in a game with a relatively low projected total of 7.5 runs. But after Seattle added Josh Naylor and Eugenio Suarez at the trade deadline, there is a huge talent gap between these teams, which is why I am making this wager with my White Sox vs. Mariners prediction.

The Mariners are 29-19 since June 13 (fifth-best in the majors). Seattle has covered the runline in just 29.2% of its home games, but this new look squad has won by two or more runs in 10 of its last 14 victories, making this a more confident White Sox vs. Mariners best bet.

Mariners righty Logan Gilbert is lights out at home with a 2.27 ERA, .144 OBA, and an almost 9:1 K:BB ratio in nine home starts. So I am laying the -1.5 runs with four stars of confidence after using a BetMGM bonus code, where a $10 winning wager would net $8.33 in profits.

Seattle’s team total is O/U 4.5 runs, and given how well Rodriguez has been swinging the bat of late, I am backing him to cross the plate as my best White Sox vs. Mariners player prop.

After the lopsided 8-3 series-opening win against the White Sox, Rodriguez was slugging .610 in his previous 24 games, a marked improvement from his .387 slugging percentage through the first 88 this season.

Rodriguez has scored at least one run in four of the last seven games and seven of the previous 13, and should be a great bet to do so going forward now that he has the protection of Naylor and Suarez in the lineup.

His recent trends justify these -110 odds at Caesars, which are a slightly better value compared to the Over being juiced to -115 at DraftKings.

What is the run line in baseball?

Mike started in the sports writing industry in July 2019, and gained a lot of followers in his first year after finishing with the No. 2 overall record in an annual NFL betting competition, which made picks against the spread, and from an Over/Under and moneyline perspective. Mike is an avid fan of the NFL, MLB, tennis, and all college sports. In his opinion, March Madness is the best sporting event there is, and he's especially euphoric starting with conference tournament time in college basketball. Mike's a big advocate of "fading the public" and making plays that are contrarian, constantly citing that "there are reasons why they have those big shiny buildings in Las Vegas." When making wagers, Mike always scours the best odds at all of the major sports betting sites, where he mostly sifts through DraftKings, FanDuel, BetMGM, and bet365. He's tried several others and is of the firm belief that bettors should not just stick to one sportsbook, as there is always likely better value to be had with the same wager. In addition, while Mike received his undergraduate degree from Villanova University, he has no issue betting against the Wildcats when it comes to college basketball wagering, and suggests other bettors should always put their “head” before their “hearts.”
