The Seattle Mariners have stopped letting anyone score. Emerson Hancock threw seven scoreless innings Sunday and the Mariners beat the Toronto Blue Jays 4-0 — their second consecutive shutout — stretching the staff’s run of scoreless baseball to 24 straight innings, dating to the third inning of Friday’s series opener.

Hancock allowed two hits, walked two and struck out five on 92 pitches, improving to 6-4 with a 3.23 ERA. He followed Logan Gilbert, who carried a one-hitter through 7 1/3 scoreless in Saturday’s 11-0 win — according to the Associated Press, the first time Seattle starters have posted consecutive outings of seven-plus shutout innings since Bryan Woo and Bryce Miller in 2024. Mitch Garver supplied the headline swing Sunday, a two-run homer, his fourth of the season.

The starters earn the ink, but a 24-inning scoreless streak requires the whole staff, and the handoffs have been just as clean. On Sunday it was Gabe Speier with a spotless eighth and Andrés Muñoz working around a hit in the ninth. That matters more than it might look in a 4-0 final: this team plays close games constantly, and the late innings are usually where its afternoons are decided. Three days of relievers recording outs without drama is the quietest good sign on the roster.

The wins pushed Seattle to 47-44 and stretched its AL West lead to 1.5 games over Texas, with Houston 2.5 back. It is not a comfortable margin — nothing about this division race is comfortable — but a weekend in which Toronto scored two runs across three games is how thin leads get defended.

Seattle is off Monday before its next series. The scoreless streak will end at some point, as they all do. The more durable development is a rotation stacking dominant starts at the exact moment the standings demand it.
