If you haven’t been watching the Seattle Mariners lately, you’re basically missing a historic power surge. Cal Raleigh isn't just "good for a catcher" anymore. He's honestly turning into one of the most feared bats in the entire league, and his recent stretch is proof. Everyone calls him "Big Dumper," but the only thing he’s dumping right now is baseballs into the bleachers.
People always talk about how catchers are supposed to be tired by the end of the season. It’s a grind. Your knees hurt, your fingers are beat up, and you’re squatting for three hours a night in the dirt. But Cal? He seems to get stronger when everyone else wilts.
Let's look at the tape.
Cal Raleigh Last 10 Games: The Absolute Numbers
When you dig into the Cal Raleigh last 10 games data, the first thing that jumps out is the sheer volume of extra-base hits. We aren't just talking about bloop singles. We’re talking about loud, high-velocity contact that makes pitchers rethink their career choices.
Over his most recent 10-game stretch, Cal has been a statistical anomaly. He’s slashing roughly .282 / .378 / .615. For the non-stat nerds, that basically means he’s hitting for a high average, getting on base at an elite clip, and slugging like a middle-of-the-order monster.
- Home Runs: 4
- RBIs: 9
- Total Bases: 24
- Walks: 6
It’s that walk-to-strikeout ratio that should actually scare people. Usually, a guy with Cal's power is a "three true outcomes" player—home run, walk, or a massive swing-and-miss. But lately, he’s been shortening his swing with two strikes and just... finding holes.

One of the standouts was the series against the Rockies. On September 24th, he went 3-for-5 with two absolute moonshots and 4 RBIs. That wasn't a fluke. It was a statement. He’s seeing the ball like it’s a beachball right now.
The Secret Sauce: It’s Not Just About Hitting
The thing most people get wrong about Cal's value is focusing only on the home runs. Yeah, 60 home runs in a season is legendary—it literally broke records for Mariners catchers—but look at what he does behind the plate during these last 10 games.
The Mariners' pitching staff has been lights out recently, and that’s not a coincidence. Cal is the floor general. He’s framing pitches at a top-tier level, stealing strikes for George Kirby and Logan Gilbert like a seasoned thief.
"He’s the smartest guy on the field. Period. He knows what a hitter is thinking before the hitter even knows." - This is the sentiment you hear around the clubhouse, and the results back it up.
During this 10-game window, the Mariners' team ERA with Cal behind the dish is significantly lower than when he’s DHing. He’s managing games while simultaneously being the most dangerous hitter in the lineup. That's a workload that would break most humans.

Breaking Down the Clutch Factor
Is he lucky? Sorta. But luck is just what happens when you hit the ball 110 mph.
In high-leverage situations over these last 10 games, Cal’s OPS (On-base plus slugging) jumps even higher. He had a massive double against the Dodgers on September 26th that basically kept the Mariners' postseason hopes breathing. He doesn't panic. You’ve probably noticed he has this calm, almost bored look on his face in the 9th inning.
That’s the face of a guy who knows he’s the best player on the field.
What This Means for the Mariners' Future
The Mariners recently locked him up with a 6-year, $105 million extension through 2030. At first, some people wondered if that was too much for a catcher approaching 30.
After these last 10 games? It looks like a bargain.

Cal is currently the heart and soul of this team. If he continues this trend of high-average hitting mixed with his natural 40-to-60 homer power, we are looking at a perennial MVP candidate. He finished as the runner-up to Aaron Judge in the 2025 MVP race, and honestly, a lot of folks in Seattle still think Cal got robbed because of the defensive value he adds.
Actionable Insights for Fans and Analysts
If you're tracking Cal's progress or looking at him for your fantasy roster, here is what you need to watch for in the coming weeks:
- Look at the pitch counts: When Cal is working 6+ pitch at-bats, he almost always wins. His eye has improved drastically.
- Watch the "oppo" power: Lately, he’s been driving the ball to left-center field more often. When he's not just pulling everything, he’s impossible to shift against.
- Check the recovery days: The Mariners have started using him as a DH more frequently to keep his legs fresh. Pay attention to his stats on the days after he DHs; he usually comes back behind the plate with a massive offensive performance.
Cal Raleigh is rewriting the script on what a modern catcher can be. He isn't just a defensive specialist who hits the occasional homer. He's a centerpiece. A superstar. And if these last 10 games are any indication, the "Big Dumper" era is just getting started.
To stay ahead of the curve, keep an eye on his hard-hit percentage (EV) over the next few series. If he stays above 45%, expect the home run barrage to continue. You should also monitor the Mariners' "Catcher ERA" to see how much of a boost he's giving the rotation compared to the league average.
