Seattle Form & Recent Results

Seattle heads into this game trying to bounce back after dropping Friday’s opener, which put them on a one-game skid. Before that loss, though, the Mariners had been playing fairly solid baseball overall, winning three of their previous five. Those three victories all came in the same stretch at home, where they took care of business with a sweep of the Angels. In Friday’s 2–0 defeat against Toronto at T-Mobile Park, the Seattle offense couldn’t find a way through, and the game ended up being decided by small margins. Starter Luis Castillo gave them a respectable outing, working six innings while giving up five hits and two earned runs. He kept his composure and limited the damage, handing out just one walk and striking out four Blue Jays, but Seattle couldn’t provide the run support needed to flip the result.

Offensively, the Mariners’ power has largely been driven by Julio Rodríguez and Luke Raley, who are tied for the team lead with 14 home runs apiece. Dominic Canzone has also been a consistent source of pop, sitting just behind them with 13 homers on the year. When it comes to bringing runners home, Cole Young has been the most productive run producer, leading the team with 41 RBIs so far this season. Randy Arozarena has been their most reliable pure hitter in terms of average, pacing Seattle with a .280 batting mark. Over their last five games, the Mariners have averaged about four runs per game, and they’ll be looking to tighten things up and avoid letting Toronto control the series as they meet again in Sunday’s finale at T-Mobile Park.

Toronto Form & Recent Results

Toronto comes into this matchup playing some of their best baseball in weeks, riding a two-game winning streak and taking three of their last five overall heading into Saturday. Those recent results include an impressive road win over Seattle, along with a pair of home victories against the Mets, showing they’ve been able to find ways to win both at home and away. Even with some ups and downs offensively, the Blue Jays have been competitive lately and are trying to build enough momentum to push themselves closer to the .500 mark.

Their most recent win was a 2–0 shutout against the Mariners on Friday, and it was fueled by a strong all-around effort. Shortstop Andrés Giménez chipped in by going 1-for-3, crossing the plate once and driving in a run, while the pitching staff did most of the heavy lifting. Starter Dylan Cease was dominant, working seven scoreless innings while giving up only three hits, issuing one walk, and striking out nine. Toronto didn’t pile on runs, but they made their opportunities count, finishing with six hits and eight total bases. Over the season, Kazuma Okamoto has been the lineup’s main power source, leading the team with 19 home runs and also pacing them in RBIs with 54. George Springer has provided additional pop with eight homers, and Ernie Clement has been their most consistent hitter by average at .295. Still, run production has been modest overall lately. as Toronto has averaged about three runs per game over the last five, so they’ll be looking for more offense to support their pitching moving forward.
