PEORIA, Ariz. — It was supposed to be routine. A standard Cactus League morning. Veterans getting loose. Prospects getting reps. Nothing that would echo beyond the back fields of the Peoria Sports Complex. But by the time the session ended on Field 1 Saturday morning, the buzz was unmistakable: the Mariners’ future may be arriving faster than anyone expected.
With most regulars out of the lineup for Seattle’s second Cactus League matchup against the San Francisco Giants, attention shifted to live batting practice. Scheduled to throw? Kade Anderson — the No. 3 overall pick in the 2025 MLB Draft. Twenty-one years old. No professional innings under his belt. Facing a lineup stacked with proven major leaguers.
It felt like a test.
It turned into a statement.
Anderson, the polished left-hander out of LSU, worked two electric innings against a group that included Rob Refsnyder, Mitch Garver, Julio RodrĂguez and Cal Raleigh. The fastball sat at 94 mph with late life. The secondary pitches — sharp, confident, thrown without hesitation — kept hitters guessing. Three strikeouts. No hits allowed. One walk. And perhaps most telling, zero signs of intimidation.
Raleigh went down swinging. Refsnyder followed. RodrĂguez, one of the sport’s most explosive young stars, couldn’t solve him either.
After the first inning, the modest crowd surrounding the practice field erupted into applause. A few fans even shouted, “You the man, Kade!” It wasn’t typical practice-field noise. It was the sound of belief forming in real time.
But if Anderson heard it, he didn’t show it.
“Nothing changes,” he said afterward, voice steady, almost detached from the spectacle he had just created. “It gives you a little bit of confidence that my stuff still plays at this level, but I’m focused on one batter at a time. Everything else will happen when it happens.”
If there were nerves about facing established big leaguers, they were invisible. Anderson worked quickly, confidently shaking off signs when necessary, dictating the tempo rather than reacting to it. For a pitcher who hasn’t appeared in a game since last June — after wrapping up his collegiate season — the crispness was startling.
The Mariners intentionally gave him time off following the draft, allowing his arm to recover before building him back up over the winter. Less than two weeks into camp, he looks anything but rusty. The command is sharp. The body language is controlled. The mindset? Already major league.
“Personally, I’m just here to strike out batters,” Anderson said with a shrug that felt more like a declaration. “Doesn’t matter where I’m at. That’s my mindset — go after guys and attack.”
It’s the kind of quote that echoes beyond a back-field bullpen. It’s the tone of someone who expects to belong.
Seattle’s rotation has been one of the organization’s strengths in recent seasons, but depth is never guaranteed over 162 games. Injuries happen. Fatigue sets in. Contenders need waves, not just stars. Anderson’s performance Saturday wasn’t just about a clean stat line in a practice session — it was about readiness.
Scouts in attendance noted his tempo. The maturity in pitch sequencing. The willingness to challenge established hitters inside. It wasn’t overpowering dominance fueled by adrenaline; it was controlled aggression. Calculated. Intentional.
There is still a developmental path ahead. Anderson has yet to make his professional debut, and the Mariners have emphasized patience in his buildup. No rush. No shortcuts. The organization has carefully managed his workload, ramping him up methodically rather than accelerating timelines based on hype.
“I feel better than ever,” Anderson said. “The Mariners have done a really good job of ramping me up for the season, really taking it under control. We’re not in any rush, so we’re able to ease into it. It’s been really nice.”
But here’s the reality: when a top-three draft pick strikes out Julio RodrĂguez and Cal Raleigh in the same morning session, timelines naturally become conversation pieces.
Could he pitch in the majors this season? It’s no longer an absurd question. It’s a whispered possibility.
Spring training is filled with flashes that fade once real games begin. But some flashes linger. Some hint at acceleration.
On a quiet Saturday morning in Peoria, Kade Anderson didn’t just throw live batting practice. He introduced himself. And if this is merely the second live BP of his spring, the Mariners — and perhaps the rest of the American League — may need to start preparing for what happens when the games truly count.
