The San Diego Padres have quickly adapted to Major League Baseball's new Automated Ball-Strike (ABS) system, which has resulted in a smaller strike zone and the ability to challenge umpire calls. This has proven beneficial for the Padres' veteran-heavy lineup, as older hitters often struggle with high fastballs, which are now more likely to be called balls. Meanwhile, the Padres' pitching staff, led by co-aces Michael King and Nick Pivetta, has also adjusted well to the new zone.

Why it matters

The ABS system is a major rules change in MLB that rewards teams and players who can quickly adapt. The Padres, with their experienced lineup and pitching staff, have so far been able to capitalize on the new zone, putting them in a strong position early in the season.

The details

The strike zone has shrunk both vertically and horizontally under the new ABS system, with high fastballs that were once strikes now being called balls. This has benefited Padres hitters like Manny Machado and Xander Bogaerts, who have seen their underlying stats improve. On the pitching side, Michael King and Adrián Morejón have the stuff to succeed in the tighter zone, while Nick Pivetta initially struggled with the changes before rebounding.

  • The ABS system was implemented at the start of the 2026 MLB season.
  • The Padres are 12-6 through their first 18 games of the 2026 season.

What they’re saying

“The pitches that are very attractive for hitters to swing at are usually a little higher in the zone. So, now, they have the ability to just not swing at 'em.”

— Craig Stammen, Padres Manager

“There's no doubt — watching these games, the zone has shrunk both (up and down).”

— Tony Gwynn Jr., Padres Broadcaster

What’s next

The Padres will look to continue their strong start and take advantage of the new ABS system as the season progresses. Their ability to adapt quickly to the rule changes could give them an edge over teams that struggle to make the necessary adjustments.

The takeaway

The Padres' veteran-laden lineup and pitching staff have so far proven adept at adapting to the new ABS system, which has resulted in a smaller strike zone. This has allowed their hitters to be more selective and their pitchers to succeed with their repertoire, putting the team in a strong position early in the 2026 season.
