PEORIA, Ariz. — When Logan Gilbert jogged to the mound for his first live batting practice of spring training, teammates did a double take — not because of a new pitch, not because of a mechanical overhaul, but because the towering right-hander was wearing full-length baseball pants instead of his trademark high socks, a subtle wardrobe gamble that symbolized something bigger: change.

For years, dating back to his college days at Stetson University, Gilbert’s knicker-style pants and high socks had become part of his identity, accentuating his 6-foot-7 frame and gangly intensity, but on this mild Arizona morning, facing hitters like Leo Rivas, Josh Naylor, Rob Refsnyder and Victor Robles, he decided to experiment.

“I’ve been wanting to try it,” Gilbert said with a shrug, before quickly admitting after the session, “I don’t think I will be doing that again. It just didn’t feel right.” High socks, it seems, will return — but the man wearing them is not quite the same.

Because the most significant adjustment Gilbert made this offseason wasn’t aesthetic or mechanical. It was personal.

On Nov. 3, just two days after the season ended, Gilbert and his wife, Aviles, welcomed their son Henry into the world — a moment that instantly recalibrated the intensity that has long defined the Seattle Mariners ace.

“It changes everything,” Gilbert said, his voice softening in a way rarely seen when discussing spin rates or pitch tunneling. “It’s been the coolest thing. Everything’s different in the best way.”

Henry and Aviles have already become regular morning spectators at Mariners workouts, a quiet presence beyond the bullpen mounds, and Gilbert’s grin when speaking about his son contrasts sharply with the hyper-competitive persona teammates jokingly call his ruthless alter ego.

The transformation is not about losing edge; it is about perspective.

In past springs, a slightly erratic live batting practice — deep counts, a few misplaced sliders, fastballs sailing arm-side — might have triggered a spiral of self-analysis, dry-work sessions and obsessive video review. Gilbert’s displeasure with missed spots was still visible Monday, but it lacked the edge of desperation that once accompanied even minor inconsistencies.

“It feels like a more well-rounded balance,” he explained. “It’s not just live and die on how my bullpen went today.”

That balance arrives at a crucial moment in his career. Gilbert is coming off a season that tested his durability for the first time, as forearm tightness forced him onto the injured list on April 26 — the first IL stint of his professional life — a humbling reminder of mortality for a pitcher who had built his identity around availability.

“When you end up on the IL, it’s like you have to figure things out again,” he said. “I was like, ‘Oh wait, I’m human.’”

Upon returning in mid-June, Gilbert delivered flashes of dominance, striking out hitters at a career-best 32.3% rate and finishing with a 3.44 ERA over 19 starts, but efficiency became elusive. Strikeouts piled up — 173 in 131 1/3 innings — yet deeper outings were rare, as he pitched into the seventh inning only three times after his return.

“It’s a balance and the best do that,” he admitted, acknowledging the tension between overpowering stuff and economical pitch counts.

The postseason magnified that fine line. After delivering six strong innings to beat Detroit in the ALDS and contributing two key relief innings in a marathon Game 5, Gilbert’s final start of the year in Toronto during the ALCS ended abruptly after four innings and five runs allowed, as disciplined hitters refused to chase his splitter below the zone.

“Personally, I felt good enough,” he reflected. “But you want to be completely, 100%, the best version of yourself.”

That hunger is rooted in precedent. In his 2024 All-Star campaign, Gilbert became the first Mariners pitcher ever to lead MLB in innings pitched with 208 2/3 while striking out 220 batters, joining an exclusive list in franchise history to surpass both 200 innings and 200 strikeouts in a single season — a benchmark he still views as the gold standard.

“Thirty-two starts, 200 innings — that’s the only thing I really care about,” he said, reiterating the mantra that has long defined him.

But now, there is an addition to that equation.

The image of Henry, tiny in Gilbert’s massive hands, reframes the stakes. The fire still burns — perhaps even hotter — yet it is anchored to something steadier than box scores and pitch counts. Coming home to a child whose face lights up at the sight of him has diluted none of his competitiveness; it has simply redistributed it.

Spring training is often a laboratory for experimentation — sometimes with pitches, sometimes with pants — but for Gilbert, this camp represents something far deeper: a recalibration of identity.

He remains the Mariners’ workhorse, the strikeout machine chasing durability benchmarks and October redemption. But he is also a father now, armed with clarity that no analytics report can quantify.

The high socks will return. The strikeouts likely will, too.

And if Gilbert’s words are any indication, the best version of him — on the mound and beyond it — might just be arriving.
