Seattle Mariners fans, brace yourselves. What felt like a slow leak in the pitching staff has now turned into a full-on collapse — and the numbers are absolutely damning. If you’ve been watching games with gritted teeth every time the bullpen phone rings, you’re not alone. These three jaw-dropping stats confirm that the Mariners’ pitching woes aren’t just bad — they’re historic.

1. MLB-Worst ERA Since May 1st: 6.45
It’s hard to sugarcoat this one. Since May 1st, the Mariners have posted a team ERA of 6.45, the worst in Major League Baseball over that span. This isn’t a rough patch — it’s a full-blown crisis. The rotation, once the team’s backbone, has crumbled under the weight of injuries, inconsistency, and a glaring lack of depth. Even reliable arms like George Kirby and Logan Gilbert have struggled to string together quality starts.

2. Opponents’ Batting Average Over .300 in High-Leverage Situations
Pitching in the clutch? Not for this team. In high-leverage moments — defined by Baseball Reference as game situations where pressure is highest — Mariners pitchers are allowing opponents to hit .312. That’s not just bad. That’s can’t-hold-a-lead-to-save-their-season bad. Every time Scott Servais turns to the bullpen with a one-run lead, it’s a coin flip at best.

3. Blown Saves: 12 in Just 45 Games
The bullpen was supposed to be a strength, but it has imploded spectacularly. The Mariners have already blown 12 saves in just 45 games. That puts them on pace for 43 blown saves this season — a number that would shatter franchise records and possibly cost them a playoff berth. And yes, that’s assuming they even stay in the Wild Card conversation.

Bottom Line: This Isn’t a Slump — It’s a Warning Sign
Fans have every right to be frustrated. The numbers don’t lie, and they paint a clear picture of a pitching staff in freefall. If the Mariners can’t turn this around — and soon — the 2025 season could go from promising to punishing in a hurry.
Pitching wins championships. Right now, the Mariners are pitching themselves right out of the race.

What’s Next?
Can the front office swing a trade to patch the holes? Will a shake-up in the bullpen stabilize the bleeding? Stay tuned — because if this collapse continues, the Mariners’ season could be dead in the water by the All-Star break
