Blue Jays vs Mariners Prediction 28 August 2026
📡 The series in Toronto kicks off with one of the hottest pitching streaks of August. Dylan Cease comes in at 8-5 with a 2.37 ERA and has already racked up 209 strikeouts. Seattle arrive with a 64-70 record, still hanging around the wild card race. The Mariners’ starting pitcher is officially listed as TBD on MLB’s site, though StatMuse suggests Emerson Hancock will get the nod. This uncertainty is crucial when assessing the odds.
Head-to-Head
📊 The last 10 head-to-head meetings are split evenly at 5-5. The July series this season stands out: Toronto took the opener 2-0, but Seattle bounced back with emphatic 11-0 and 4-0 victories. Two of those three games ended in shutouts, and in two contests the combined score stayed under 7.5 runs.
Head-to-head statistics Blue Jays - Mariners

Toronto Blue Jays Team Overview
The Blue Jays are 65-69 and remain within striking distance of a wild card spot. Over the course of the season, their offense has produced almost exactly as many runs as Seattle-527 to 526-so neither side holds a clear, consistent edge at the plate. In recent weeks, Toronto have become increasingly reliant on the strength of their rotation, and tonight they turn to the best arm currently on their roster.

Seattle Mariners Team Overview
The Mariners have shown signs of life in recent weeks, racking up eight wins in their last 13 games. The team still relies heavily on the power hitting of Cal Raleigh and Julio Rodriguez, while their overall batting average remains low-hovering around .228. Facing Cease, this lineup once again runs the risk of piling up strikeouts and struggling to string together consistent hits.

⚾ Starting Pitchers
Dylan Cease is enjoying a stellar run of form. Over his last five starts, he’s posted a 2.03 ERA and racked up 42 strikeouts in 31 innings. In his two most recent outings against the Yankees, the right-hander gave up just three earned runs over 13 innings, allowing only four hits. Back in July, Cease also tossed a complete-game shutout against Boston.
MLB has yet to officially announce Seattle’s starting pitcher, but StatMuse lists Emerson Hancock-who’s 7-7 this season with a 3.37 ERA and a 1.12 WHIP. If Hancock does get the nod, there’s a notable recent benchmark: on July 5, he threw seven scoreless innings against Toronto, giving up just two hits. In his last four starts, Hancock hasn’t allowed more than three earned runs in any outing.
⭐ Editor's Pick
Cis gives Toronto a strong chance to hold Seattle to just two or three runs. His August form has been at an elite level for several weeks now, and his high strikeout rate is a real problem for this current Mariners lineup. The uncertainty over the visitors’ starting pitcher adds some risk, but if Hancock gets the nod, his July outing against Toronto suggests a low-scoring game is likely. Both teams have scored around 526-527 runs this season and neither ranks among the league’s most consistent offenses. We’re backing the under 7.5 total runs in this matchup.
