The Mariners are a team that loves a catchy slogan. Go to batting practice or a pregame workout and you’ll see a host of players wearing shirts with more acronyms than an intro-level business course: “DMGB” (Doesn’t Matter, Get Better) is popular, as is “27 outs, no more” favored by Perry Hill’s pupils, while pitchers often sport “DTZ,” standing for Dominate the Zone (formerly CTZ, Control the Zone). That last one has been around for the majority of the Dipoto era, so familiar now that it fades to background noise, and usually makes itself most evident when Mariners pitchers are efficiently mowing through opposing lineups.
