- Aug 8, 2026
The move opens up a spot on the 40-man roster that the Mariners needed for Miles Mastrobuoni, whose contract was selected from Triple-A Tacoma after Julio Rodriguez (concussion) was placed on the 7-day IL. Criswell was diagnosed with a Grade-1 pectoral strain in mid-June but has since been tagged with a shoulder strain. The move to the 60-day IL doesn't change his projected return for early August, though a clearer timeline will be established once Criswell embarks on a rehab assignment.

The read
Over his last 10 games, Cooper Criswell has gone over 0.5 K 5 of 10 decided times (50%) — versus 58% across the full season. His game-to-game K have been highly variable (σ ≈ 1.2), so short streaks can mislead. These are descriptive stats about past games, not predictions or betting advice.

Edge vs
Hit rate excludes pushes from the denominator. Confidence uses a 95% Wilson interval — a high recent rate on few games still reads as low confidence. Season over rate at this line: 58%.
