Sportsbook Odds Analysis

The Red Sox come in as the slight favorites in the matchup at -125 with the Mariners not far behind at -105. The total sits at 8 runs while the OVER is 9-1 in the last 10 games between these two teams.

Starting Pitchers Analysis

Logan Gilbert is set to take the mound for the Mariners, sporting a 5-5 record with a 5.10 ERA through 20 starts. The 24-year-old rookie has been particularly cold recently, holding a 0-3 record and a 7.09 ERA over his last seven outings. He took a no-decision in his most recent start against the Houston Astros, allowing six hits and two earned runs through 4.1 innings.

Boston will counter with Eduardo Rodriguez. The left-hander is 11-8 on the season with a 5.15 ERA over 27 starts. Rodriguez will look to bounce back from his most recent outing against the Tampa Bay Rays, who lit him up for eight hits and six earned runs over just 3.2 innings.

Seattle News & Notes

The Mariners have been consistently chugging along this season with their only losing month coming in May. Despite their consistent winning ways, they find themselves on the outside looking in on the AL wild-card race. At 77-66, they’re three games back of the Red Sox and Blue Jays, while they’ll have to leapfrog the Yankees and Athletics as well.

Kyle Seager has done a lot of the heavy lifting for Seattle’s offence this season with 34 home runs, 94 RBIs and a slugging percentage of .449. Unfortunately, the third baseman hasn’t had much help as the Mariners offence sits 22nd in the majors, producing just 4.26 runs per game.

Boston News & Notes

At 81-64 with a grip on an AL wild-card spot, the Red Sox find themselves in a favorable position – for now. With 17 games remaining on the schedule, including a big three-game set vs the Yankees, they can’t afford a slip-up here against Seattle.

Rafael Devers has been Boston’s standout performer this season, leading the Red Sox to 5.07 runs per game (fourth in the majors). The third baseman is hitting .274 with 33 home runs and 102 RBIs. Devers has cooled off slightly of late, with just five hits and two RBIs over his last six games, but the mini drought shouldn’t last much longer.

Staff Betting Pick: OVER 8 runs

With mashers throughout the Red Sox lineup and a struggling rookie on the mound for the Mariners, it seems like a safe bet to take the OVER on Monday. Add in the fact that the OVER is 9-1 in the last 10 meetings between these teams, and the decision is an easy one.
