Philadelphia Phillies catcher J.T. Realmuto demonstrated his expertise behind the plate, getting two strikeouts for pitcher Jesús Luzardo without him having to throw extra pitches or face another batter in the first inning of Luzardo's spring training debut. Realmuto successfully challenged two close pitches through the new Automated Ball-Strike System (ABS), or "robot umpires," that will be used in the regular season for the first time this year.

Why it matters

The new ABS system is a major rule change for the 2023 MLB season, and Realmuto's ability to effectively leverage it to support his pitcher's performance highlights the strategic importance of having a savvy, experienced catcher on the roster. This could give the Phillies an advantage, especially early in the season as players and teams adjust to the new technology.

The details

In the first inning, Luzardo struck out three batters in a row. The second and third outs were called third strikes, both of them initially balls before Realmuto challenged the calls through the ABS system. The challenges showed the pitches were actually within the strike zone, resulting in the strikeouts. Luzardo finished his outing with five strikeouts over three innings, throwing 27 of his 38 pitches for strikes.

  • On March 6, 2026, the Phillies played a spring training game against the Boston Red Sox.
