Toronto Blue Jays vs Seattle Mariners

Toronto Blue Jays at Seattle Mariners (2026-07-05). Trey Yesavage vs Emerson Hancock at T-Mobile Park.

Yesavage has given Toronto solid rotation value through 12 starts, working 67.1 innings with a 3.34 ERA, 1.10 WHIP, 8.15 K/9, and 4.01 BB/9. The profile is effective but not perfectly clean, as the walk rate remains the main pressure point, and his recent game log shows that clearly with 20 total walks across his last seven starts despite only 22 earned runs allowed in that span. Even so, he has allowed one earned run or fewer in three of his last four outings, including 6.2 innings of one-run ball against the Mets and 5.2 innings of one-run work versus Houston. Hancock has logged more volume at 90.2 innings over 16 starts and carries a comparable 3.47 ERA with a slightly better 1.05 WHIP, plus stronger command indicators at 8.64 K/9 and 2.18 BB/9. His recent trend is less steady than the season line suggests, with 11 earned runs over his last three starts before a partial rebound against Cleveland, and his quality-start rate sits at just 20 percent.

At the team level, these offenses are closely matched by OPS, with Toronto at .692 and Seattle at .694, but they get there differently. The Blue Jays hit for a better average at .245 and strike out less, while the Mariners bring more power with 108 homers versus 88 and have scored slightly more runs, 368 to 356, despite a lower batting average. The larger separation is on the pitching side, where Seattle owns the stronger staff numbers with a 3.59 ERA and 1.17 WHIP compared with Toronto's 4.12 ERA and 1.31 WHIP. Seattle has also done a better job limiting damage, allowing 80 homers against 101 for Toronto.

The recent head-to-head sample from 2025 was split evenly at three wins apiece, but the scoring environment varied sharply, from a 3-1 game to multiple games with nine or more total runs. That mixed history fits a 7.5 total that sits in the middle of this matchup: both starters bring sub-3.50 ERAs and decent swing-and-miss ability, yet Yesavage's walk volatility and Hancock's uneven recent form leave room for innings to turn quickly. With two lineups separated by only two points of OPS, the total is being driven more by run prevention expectations than by any major offensive gap.
