Starting Pitchers

George Kirby pitched four innings against the New York Mets last Saturday and allowed three hits and one earned run in a 5-4 Mariners loss. The rookie is off to an impressive start through his first two big-league outings with a tidy 0.90 ERA and a 0.80 WHIP in 10 innings pitched.

Rich Hill led the Red Sox to an 11-3 win last Saturday, allowing only two earned runs across six innings in his longest outing of the season. The 42-year-old carries a 2.89 ERA and a 1.11 WHIP into Thursday night’s start. Hill owns a 2.64 ERA and a 1.17 WHIP in 44.1 career innings pitched against Seattle.

Seattle Found Some Offense In Its Series Finale Against Toronto

Ty France went 3-for-5 with a home run and two RBIs in Seattle’s 5-1 win over the Toronto Blue Jays on Wednesday night. France has been Seattle’s best hitter in 2022 with a .325 batting average, six home runs and 27 RBIs, but his supporting cast has failed to produce consistently.

The Mariners are now 7-2 in their last nine games when scoring five or more runs and 2-13 in the last 15 games when they have scored four runs or less. Bettors taking Seattle as their Mariners vs Red Sox prediction will be hoping the offense can get to this magic number of five runs on Thursday.

Boston Is Playing Well After Long Slump

The Red Sox earned a 2-1 series win over the Astros with their 5-1 victory over Houston at home on Wednesday night. Boston managed to average five runs per game against a Houston team that owns the best ERA in baseball. After struggling on offense during their 3-12 slump, the Red Sox are averaging 5.75 runs per game over their current 5-3 run. 

Rafael Devers has been the driving force behind Boston’s turnaround on offense. The 25-year-old is batting .410 in May with four home runs, 12 runs and 12 RBIs this month. Devers leads the team in batting average (.340), home runs (seven), runs (25) and RBIs (21) this season.

Mariners vs Red Sox Pick & Insights

Mariners: Keys To Victory

As mentioned above, Seattle’s success is tied heavily to its production on offense. This will be especially true against the Red Sox given how well they are hitting the ball. Both starting pitchers are solid in this matchup, but offense will be the key to a Mariners vs Red Sox prediction victory.

Red Sox: Keys To Victory

Rich Hill had pitched 13 scoreless innings prior to allowing two earned runs in his last start against the Rangers. Hill has always been an excellent pitcher when he isn’t injured, and he should make Boston a popular Mariners vs Red Sox pick in this matchup.
