Starting Pitchers

Marco Gonzales allowed five hits and one earned run in 6.2 innings pitched last Friday in a 2-1 Seattle win over the New York Mets. Gonzales is 1-4 this season with a 3.38 ERA and 1.53 WHIP in 32 innings. The Mariners have averaged only 1.5 runs per game on offense in his last four starts.

Kevin Gausman is enjoying a strong first season in Toronto with a 3-2 record, a 2.40 ERA, a 0.98 WHIP and 54 strikeouts in 45 innings. Gausman owns a rock-solid 2.63 ERA and a 1.10 WHIP in 41 career innings against Seattle.

Seattle Has Been Reeling Since The End Of April

The Mariners appeared to be building on last year’s 90-win campaign with an 11-6 record through their first 17 games in 2022. But that solid start has given way to a 5-15 slump over the team’s last 20 games. Seattle is 1-10 in its last 11 games against American League opponents.

The club’s 3.90 team ERA and 3.81 runs scored per game both rank 21st in the majors. With the Astros and Angels both entering Wednesday’s action with 24 wins, the Mariners will have to turn things around in a hurry if they hope to compete for a playoff spot in the AL West this season.

Toronto’s Offense Has Struggled During Recent Slump

The Blue Jays have won three of their last four games thanks to their pitching staff, which has surrendered only 1.5 runs per game over this current 3-1 run. Toronto has averaged an underwhelming 3.22 runs per game on offense in its last nine games and is 3-6 over that stretch.

This group ranked third in the majors in runs scored last season at 5.22 runs per game. This year Toronto ranks 22nd in MLB with 3.76 runs per game. Bettors taking Toronto as their Mariners vs Blue Jays prediction will be looking for more production out of the offense  in Wednesday’s series finale.

Mariners vs Blue Jays Pick & Insights

Mariners: Keys To Victory

Seattle has scored only two runs in this series and will now face Toronto’s best pitcher in Kevin Gausman. It’s hard to imagine the Mariners ending their offensive slump in this one, so it will be up to Marco Gonzales to pitch well enough to give the Mariners a shot at pulling off a Mariners vs Blue Jays prediction upset.

Blue Jays: Keys To Victory

With Gausman on the mound against this struggling Seattle offense, the margin for error should be pretty large for the Blue Jays. As long as the offense doesn’t get completely shut down, Toronto should get the job done here as a chalky Mariners vs Blue Jays pick.
