Oakland A's Evaluate Roster Battles in Cactus League

Spring training stats may not tell the full story as players fight for jobs and roster spots

Feb. 21, 2026 at 6:40pm

As the Oakland Athletics open their Cactus League schedule, the focus will be on evaluating key position battles and roster spots rather than relying too heavily on spring training statistics. Players like Matt Muncy, Brett Harris, Darell Hernaiz, and Denzel Clarke will be closely watched as they compete for the starting third base job and bench roles.

Why it matters

Spring training games provide an opportunity for players on the roster bubble to make their case, but the unique conditions of the Cactus League mean that traditional stats may not be the best indicator of a player's readiness for the regular season. Evaluating factors like defensive improvements, swing adjustments, and plate discipline will be crucial in determining who wins jobs.

The details

The A's will be looking to see if Muncy has improved his defense at third base after struggling there in 2025, and whether he can regain the offensive form that made him a promising prospect. Harris and Hernaiz, Muncy's main competitors at third, will need to demonstrate they can drive the ball with more authority to earn serious consideration. Outfielder Denzel Clarke will get a long look with Perez starting in center field, as the A's evaluate whether he has the plate discipline to complement his power potential.
