What is the story about?

Here’s something I never thought I’d say: I am excited to watch Emerson Hancock pitch tonight.

The Mariners look to win their first series of the season Saturday against the Angels. They won Friday’s opener 4-0 in a long, frustrating, 10-inning game that didn’t really get going until the end. The bats did eventually come alive, just in time to ruin the Angels’ home opener.

Hancock will take the mound looking to make it two in a row for the Mariners and for himself. Hancock threw six no-hit innings

last week against the Guardians, striking out nine in the process. He seemed to pick right up where he left off after switching to the bullpen at the end of last year, with improved velocity capable of generating a competitive number of whiffs.

One change he made in that first start was lowering his arm slot even further, continuing his trend from his brief days as a reliever. The improved Stuff+ numbers held in his first start of 2026. With three kinds of fastballs, a changeup, and a sweeper — all thrown from a low arm slot — Hancock now has all the makingss of a contemporary starter, even if “just OK” velocity limits him to a mid-rotation arm. There’s still a lot more to prove, of course, but the lack of depth in the Mariners’ rotation last year is what kept them from a more impressive win total. Hancock pitching anywhere above replacement level would be a crucial development early in 2026.

The Mariners will face Angels’ righty Jack Kochanowicz, who Jake Mailhot covered in our series preview. Brendan Donovan is out of the lineup after exiting Friday’s game with a leg injury after stepping awkwardly on first base while trying to leg out a grounder. Leo Rivas takes his place at third, and Luke Raley moves up to the leadoff spot.
