WHITE SOX CATCHER EDGAR QUERO SHOWS HE KNOWS HOW TO USE ABS CHALLENGE SYSTEM ON OPENING DAY
By Billy Heyen

Opening Day in Major League Baseball (MLB) always brings excitement, and this year, one player stood out by fully embracing a new tool in the game – the Automated Ball-Strike (ABS) challenge system. On Thursday, as the season kicked off, Chicago White Sox catcher Edgar Quero made a statement by challenging the strike zone more times than anyone else, and he didn’t just make noise – he was successful, too.

A New Era of Challenges
In the 2026 MLB season, the ABS challenge system allows players to contest ball-strike calls made by the umpire. The system provides an opportunity for players to review decisions and challenge calls they believe are incorrect. On Opening Day, MLB saw 30 total challenges, but one player was more active than anyone else – Edgar Quero.

Quero, who was behind the plate for the White Sox, issued a total of four challenges. What’s more impressive is that he succeeded in three of those challenges, demonstrating his understanding of the new system and his ability to use it to his advantage.

This level of engagement with the ABS challenge system is not just rare for a catcher, but it shows Quero’s keen awareness of the game and how he can influence calls to benefit his team. His performance on Opening Day sets a high standard for other players in the league to follow.

The Numbers Don’t Lie
Thanks to detailed data from Baseball Savant, it’s clear that Edgar Quero led the league in both the total number of challenges he issued and the number of successful outcomes. He wasn’t just randomly calling for challenges; his decisions were based on his judgment and knowledge of the game, leading to three successful calls.

In fact, Quero’s performance was so dominant that no other player came close to matching his level of success. The only other player who came close was Francisco Alvarez of the New York Mets, who went 2-for-2 with his challenges. Quero’s higher number of attempts and victories on Opening Day is a remarkable achievement and demonstrates his confidence in the ABS system.

Quero’s Role with the White Sox
For the White Sox, Edgar Quero’s use of the challenge system on Opening Day speaks to the trust that the team has in him behind the plate. Not only is he handling the responsibilities of catching and calling a game, but he’s also using every tool available to ensure that his team benefits from the most accurate ball-strike calls.

Interestingly, Quero was the only White Sox player to use the challenge system on Opening Day. None of their hitters called for a challenge, which may indicate that the team is relying on Quero’s judgment to make those decisions. It will be intriguing to see if this trend continues as the season progresses. Some teams may even prefer to keep challenges reserved primarily for their catcher, recognizing that catchers are often in the best position to judge the accuracy of strike zone calls.

The Impact of the Challenge System Moving Forward
While the data from Opening Day is still in its early stages, it will be fascinating to see how the use of the ABS challenge system evolves. There’s bound to be some statistical noise in the early going, but as the season progresses, patterns will emerge, and teams will adjust their strategies accordingly.

It’s possible that the White Sox, recognizing Quero’s success with the challenge system, will continue to lean on him to make those calls. He’s proven that he’s reliable when it comes to challenging incorrect ball-strike calls, and his performance could influence the team’s approach to challenges moving forward.

A Strong Start to the Season
For Edgar Quero, his strong use of the ABS challenge system comes at a pivotal point in the season. With Kyle Teel expected to return from injury, there will be a balance to strike in terms of playing time between Quero and Teel. For now, though, Quero is firmly entrenched in his role as the starting catcher, and if he continues to excel behind the plate, he could solidify his place as one of the most trusted figures on the team.

On Opening Day, Quero demonstrated that he is not just a catcher but also a savvy player who understands how to leverage technology to his advantage. If he keeps getting those calls right, he could continue to make a significant impact for the White Sox this season.

Looking Ahead
As the season unfolds, it will be interesting to track how Quero and other players adapt to the ABS challenge system. There’s no doubt that this tool will change the way the game is played, and Quero’s success on Opening Day is a promising sign that he’s ready to make the most of it.

Whether the White Sox continue to rely on Quero’s expertise or if other players start to use the challenge system more frequently remains to be seen. But one thing is clear: Edgar Quero’s performance on Opening Day has already made an impact, and fans can expect to see more of his savvy decision-making throughout the season.

Conclusion
Edgar Quero’s Opening Day performance shows that he is a player who not only embraces new technology but also knows how to use it effectively to influence the game. By leading the league in ABS challenges and succeeding in the majority of them, he’s set himself apart as a player who can make a real difference for the White Sox. As the season continues, it will be exciting to see how his use of the ABS challenge system evolves and how it affects his role within the team.
