Mariners pitchers took a huge step back in 2026. Cal Raleigh seems to know why.

Zachary Rymer argues that Seattle Mariners catcher Cal Raleigh correctly identified the core issue behind the pitching staff's struggles in 2026. Raleigh pointed out that opponents became overly aggressive because the Mariners' strike-zone-focused approach became excessively predictable. After finishing 19th in MLB with a 4.20 ERA and allowing 194 home runs, Seattle needs to overhaul its tactical philosophy.
Rymer highlights that Seattle led MLB by throwing 66.0 percent first-pitch strikes, but opposing hitters capitalized with a league-high 36.5 percent first-pitch swing rate. The writer suggests the Mariners must listen to Raleigh's advice to prioritize execution and winning over pursuing statistical targets, recommending changes such as pitching backward or varying early-count pitch selection.
