SCOTTSDALE, Ariz. — The anticipation was unmistakable the moment Roki Sasaki strode to the mound Wednesday afternoon, shoulders square, eyes locked on home plate, armed with a fastball that has electrified scouts for years and expectations that have only grown louder since he joined the Los Angeles Dodgers, but what unfolded in his first Cactus League start of 2026 was not the crisp statement outing many envisioned, instead serving as a jarring reminder that even the most gifted arms must battle inconsistency, timing, and the unforgiving rhythm of early spring baseball.

Sasaki, entering his second season in Los Angeles determined to transition from intriguing bullpen weapon to dependable rotation fixture, labored through a rocky first inning against the Arizona Diamondbacks, surrendering three runs on three sharply struck hits and two walks, with only 17 of his 36 pitches finding the strike zone, a stark imbalance that forced him into hitter’s counts and invited loud contact; his fastball flashed elite velocity, topping out at 98.6 mph, and he did punch out three batters, but the raw power could not mask the command issues that quickly spiraled into trouble.

The inning unraveled swiftly as Geraldo Perdomo opened with a hard-hit single, Tim Tawa drew a walk, and with one out Nolan Arenado lashed a line-drive double to left that plated the game’s first run, igniting the Diamondbacks’ dugout; moments later Ildemaro Vargas followed with another double, driving in two more and staking Arizona to a 3-0 lead before many fans had settled into their seats, the kind of early damage that forces even the calmest pitchers to search for answers mid-inning.

A mound visit from pitching coach Mark Prior momentarily steadied the storm, and Sasaki responded by striking out Jordan Lawlar and Ryan Waldschmidt to halt the bleeding, offering a glimpse of the dominance that made him such a coveted arm, yet the inconsistency resurfaced in the second when he struck out Druw Jones but walked Aramis Garcia and was lifted shortly thereafter, his afternoon ending with as many questions as strikeouts.

“There were some positive things, but also things I need to work on,” Sasaki said through an interpreter, his tone measured rather than rattled, though his admission carried weight for a pitcher trying to solidify his place in a championship-caliber rotation; he elaborated that while his forkball and four-seam felt sharp in the bullpen, the transition to game speed disrupted his feel, noting, “In the bullpen, I felt pretty good about the forkball, but once I got on the mound, it didn’t go well, and the four-seam felt a little off.”

Manager Dave Roberts offered a diagnosis that blended reassurance with constructive critique, observing, “I thought he was overthrowing, I hadn’t seen that all spring, he was a little too bullish on the fastball and getting behind in the first inning,” before pointing out that Sasaki’s second frame showed improved pitch mix and command, subtle progress that could easily be overlooked amid the box score damage.

The stakes for Sasaki this spring are unmistakable, because while he proved last postseason that he can thrive under pressure—allowing just one run over 10.2 playoff innings in a high-leverage relief role—the Dodgers envision something larger, a starter capable of navigating lineups multiple times and complementing a rotation already brimming with talent, and to do that he must refine not only his command but also the third pitch he spent the offseason developing, a slider-cutter hybrid Roberts has described as a potential difference-maker.

Spring training, of course, is designed for experimentation and recalibration, and Los Angeles ultimately secured a 10-7 victory, softening the sting of Sasaki’s uneven outing, yet the performance underscored how thin the margin can be between dominance and damage when command wavers even slightly; elite velocity alone cannot rescue a pitcher who falls behind early, particularly against disciplined hitters eager to ambush predictable fastballs.

Elsewhere on the mound, River Ryan delivered a scoreless inning and Edwin Díaz added a clean frame of his own, subtle reminders that competition for innings within this pitching staff remains fierce, and that every appearance carries evaluative weight in a clubhouse chasing another title.

For Sasaki, the narrative is far from written, and if anything Wednesday’s turbulence may serve as the necessary friction that sharpens his edge before Opening Day, because the Dodgers are not merely seeking flashes of brilliance but sustained reliability, the kind that withstands October pressure rather than buckling under it.

The fastball is still electric, the forkball still dives with late bite, and the belief inside the organization remains intact, yet as Sasaki walked off the mound beneath the Arizona sun, the lesson was unmistakable: talent opens the door, but command keeps it from slamming shut, and until he aligns the two with consistency, every outing will carry both promise and peril.
