SEATTLE — The numbers told an uncomfortable truth last season: the Seattle Mariners could score, but they could not set the table. Despite finishing as a top-10 offense in runs, their production from the leadoff spot hovered near the bottom of Major League Baseball, ranking 27th in OPS and 24th in both on-base percentage and wRC+, a statistical contradiction that ultimately left too many rallies stalling before they ever truly began.
Now, in a move that could quietly reshape the identity of their lineup, Seattle is handing the keys to Brendan Donovan, and if early evaluations are any indication, this is not just a tweak — it’s a calculated shift in philosophy.
For much of last year, the Mariners scrambled at the top of the order after Victor Robles fractured his shoulder on the season’s first road trip, forcing manager Scott Servais to cycle through a revolving door that included Julio RodrĂguez, Dylan Moore, J.P. Crawford and eventually Randy Arozarena; there was talent in that mix, but there was no stability, and the results were glaring — a collective .237/.311/.348 slash line and a .659 OPS from the leadoff position, numbers that simply do not ignite an offense built on pressure and depth.
Arozarena, tasked with the role late in the season, hit just .218 with a .302 on-base percentage when leading off, and while Crawford demonstrated patience by seeing more than four pitches per plate appearance, the production rarely matched the grind. The Mariners weren’t lacking effort; they were lacking impact.
Enter Donovan, whose career .282/.361/.411 slash line and .772 OPS over four seasons immediately signal a different profile. He may not overwhelm with tape-measure home runs — his 162-game average sits at 13 — but the 32 doubles per full season and a contact-first approach paint the picture of a hitter designed to create discomfort for opposing pitchers from the first pitch of the game.
“He’s just a better hitter,” Seattle Sports analyst Mike Salk said bluntly on Brock and Salk. “He should be getting on base more, hitting more doubles, putting pressure on the other team. The batting average should jump by 50 points or so. The OPS should be a lot higher. He’s just a flat out better hitter than what they had there last year.”
That assessment is not hyperbole when placed against the strikeout disparity alone. Mariners leadoff hitters combined for 165 strikeouts in 2025; Donovan averages 89 over 162 games. That is not incremental improvement — it is transformative.
“It’s a crazy difference,” Salk emphasized.
In an era defined by three true outcomes, Donovan represents a throwback irritant — the type of hitter who shortens swings, fouls off borderline pitches and forces starters into uncomfortable counts. Interestingly, he actually averaged fewer pitches per plate appearance last season than Crawford or Arozarena, but the distinction lies in the outcome. When Donovan works deep, he cashes in. He gets the single through the right side. He slaps the double into the gap. He refuses to give away at-bats with empty strikeouts.
Salk described him as “a real pest,” and that may be the most important trait of all. Not flashy. Not headline-grabbing. Just relentless.
The Mariners do not need Donovan to be RodrĂguez. They do not need him to launch 35 home runs. What they need is traffic — baserunners who turn the lineup over and amplify the damage potential of the sluggers behind him. At T-Mobile Park, where power can be muted by marine air and spacious alleys, doubles and disciplined contact often matter more than towering blasts.
And if Donovan adapts to the dimensions, learning which gaps to target and which pitches to drive, he could become precisely the type of tone-setter Seattle has lacked — a hitter who steps in during the first inning and immediately forces a pitcher to throw seven, eight, nine stressful pitches before recording an out. That kind of exhaustion compounds. It lingers into the third and fourth innings. It opens cracks that middle-of-the-order bats can exploit.
The psychological effect should not be underestimated either. Pitchers thrive on rhythm. A quick first out calms nerves and settles tempo. Donovan threatens that comfort. A leadoff double, a grinding nine-pitch walk, or even a bloop single that extends an inning shifts energy instantly. It is subtle, but over 162 games, subtle edges accumulate into tangible wins.
For a club intent on pushing deeper into October, the upgrade at the top is about more than numbers; it is about identity. The Mariners want to be relentless. They want to be annoying. They want opposing starters glancing toward the dugout by the fourth inning, already fatigued.
If Donovan delivers even close to his career norms, the statistical jump alone will justify the decision. But if he evolves into the irritant Salk envisions — the “real pest” who refuses to concede at-bats — then Seattle’s lineup transformation may begin not with a thunderous swing, but with a stubborn one.
The Mariners were already dangerous last year. With Donovan setting the table, they might finally be complete.
