As the 2025 MLB season approaches, Commissioner Rob Manfred spoke at spring training media day in Arizona, addressing major topics such as the Dodgers’ massive spending, the upcoming collective bargaining agreement (CBA), recent rule changes, and the introduction of the automated ball-strike (ABS) challenge system. With several rule modifications already reshaping the game, MLB is taking the next step by testing automated strike zone technology during spring training.

Automated Ball-Strike Challenge System to Be Tested

One of the most talked-about developments for the 2025 season is MLB’s plan to test the ABS challenge system. Instead of completely replacing umpires with robotic strike zones, the league has opted for a challenge-based model, allowing players to contest a limited number of ball-strike calls.

Under this system:

• Teams get two challenges per game (they keep them if successful).
• Only the batter, catcher, or pitcher can challenge a call.
• Challenges must be made immediately after a pitch—no dugout input is allowed.
• The Hawkeye tracking system will quickly determine if the call was correct, displaying the result on stadium videoboards and broadcasts.

The system was successfully tested in Triple-A last year, with calls being reviewed in an average of 17 seconds. MLB hopes to further refine the technology before deciding on its long-term use in the majors.

Manfred on the Dodgers’ Spending and Competitive Balance

Manfred also addressed concerns over the Los Angeles Dodgers’ record-breaking payroll, which skyrocketed after their signings of Shohei Ohtani and Yoshinobu Yamamoto. While some fans worry about big-market teams dominating the league, Manfred defended the Dodgers, stating that they are operating within the system’s rules.

“If I’m going to be critical of something, it’s not going to be the Dodgers—it’s going to be the system,” Manfred said. He acknowledged that the real issue is not teams spending too much but rather teams that aren’t spending at all, which negatively impacts fan morale.

CBA Negotiations and Future Labor Talks

With the current MLB collective bargaining agreement (CBA) set to expire in December 2026, Manfred avoided speculating on upcoming labor negotiations. While many anticipate another lockout in 2026-27, he emphasized that talks with team owners must come first before any public discussions.

“I owe it to the owners to coalesce around a bargaining approach,” he said, adding that he does not want to distract fans with labor disputes this early.

Rule Changes Have Been Well Received

MLB’s recent rule changes, such as the pitch clock, shift ban, and limited pickoff attempts, have been a success both on and off the field. Manfred cited increased fan engagement and attendance growth for three consecutive seasons, crediting the rule adjustments for making baseball faster, more exciting, and more action-packed.

“The teams have been more positive about the rule changes than I expected,” he said. “It’s not just about the minutes—it’s about the action and athleticism that fans were looking for.”

What’s Next for MLB?

With automated strike zones being tested and rule changes reshaping the game, MLB continues to push toward modernization while balancing traditional elements. While payroll disparities and labor negotiations remain challenges, the league is optimistic about its continued growth.

As teams prepare for the 2025 season, all eyes will be on how these new changes impact the game—and whether MLB’s embrace of technology will lead to more significant shifts in the future.
