OAKLAND, July 21 — Donovan Walton didn’t start Tuesday night’s game. He entered in the bottom of the seventh inning, taking over for Joshua Kuroda-Grauer at third base, a defensive substitution that, by itself, hardly makes headlines. But for Walton, a 30-year-old utility infielder who has spent parts of five seasons bouncing between the majors and Triple-A, that moment represents the latest chapter in a career defined by adaptability.
And for the Athletics, it now signals a larger shift on the infield.
Behind the Substitution
Kuroda-Grauer, the Athletics’ regular third baseman, has been placed on the 10-day injured list, a move that opens a significant hole in the lineup. The team confirmed the roster move after Tuesday’s game, though no details on the nature of Kuroda-Grauer’s injury were provided. What is clear is that Walton, who was called up from Triple-A earlier this season, will see increased playing time at the hot corner during Kuroda-Grauer’s recovery.
This is not a situation the club had planned for. The Athletics may also call up another infielder from the minors to provide depth, but for now, the weight falls on Walton.
And he has been in this spot before — the player who steps in when someone else goes down.
A Career of Moving Around
Walton made his Major League Baseball debut in 2021 with the Seattle Mariners. Since then, he has worn the uniforms of three organizations, including a stop with the San Francisco Giants, before arriving in the Athletics system. His journey has been one of steady, unglamorous reliability.
In the majors, he has played second base, shortstop, and third base — a defensive versatility that makes him valuable precisely because he can fill almost any gap. That flexibility is what brought him to Oakland’s attention.
Through the 2025 season, Walton’s career batting average sits at .244, with approximately 10 home runs. The numbers are modest, but they tell only part of the story. His value lies in his glove and his willingness to play wherever he is needed, often on short notice.
The Human Side of the Roster Move
For a player like Walton, every call-up carries the weight of proving he belongs. Called up from Triple-A earlier this season, he had been biding his time, taking reps at multiple positions, waiting for an opportunity. That opportunity arrived Tuesday night, not in a starting role but in a defensive swap three innings from the end of the game.
Now, with Kuroda-Grauer sidelined, Walton is expected to become a regular presence at third base. The Athletics are not just replacing a player; they are trusting a utility infielder with a critical defensive position during a stretch where every game matters.
The team will rely on him, likely for several days or more, depending on how quickly Kuroda-Grauer recovers. It is a reminder, behind the statistics and the roster transactions, that baseball’s depth charts are filled with players like Walton — the ones who step into the spotlight when injuries strike.
What to Watch For
In the coming days, how Walton handles the increased workload will be worth watching. His defensive versatility means he could shift positions again if the Athletics bring up another infielder, but the immediate expectation is that third base is his. The team may also adjust its lineup to accommodate his bat, which has historically been more contact-oriented than power-driven.
For now, the story is not about home runs or batting averages. It is about a 30-year-old infielder who, on a Tuesday night in July, took the field in the seventh inning and found himself, once again, exactly where his team needed him.
