Decisive Ending to World Series Game 2

The Milwaukee Brewers moved closer to their first World Series title on Saturday night, taking a 2-0 lead over the Tampa Bay Rays after a controversial check swing call ended Game 2. The high-stakes moment unfolded in the top of the ninth with the Brewers ahead 5-4 and the Rays threatening with a runner on third base. Tampa Bay's designated hitter, Yandy Díaz, faced a 3-2 count against Milwaukee reliever Aaron Ashby when the pivotal play occurred.

The Game-Changing Umpire Call

On Ashby’s curveball, Díaz attempted to check his swing. Home plate umpire Jim Wolf initially ruled that Díaz had not swung, which would have resulted in a walk and placed runners at the corners. However, Brewers catcher William Contreras appealed the play to the first base umpire. The appeal was decisive: the first base umpire ruled that Díaz had swung, resulting in a strikeout that ended the game in dramatic fashion.

Perspectives on the Call

The decision sparked debate both on the field and among broadcasters. Díaz commented after the game, “In the moment, yeah, I disagreed. But the umpire said it was a swing and it is what it is.” Rays manager Kevin Cash also weighed in, saying that from his vantage point it looked as though Díaz had swung. Fox’s postgame analysts appeared divided on whether the call was correct.

Understanding the Check Swing in MLB

The controversy highlights an ongoing ambiguity in baseball’s rules. MLB’s official rulebook does not define a ‘check swing.’ According to MLB.com, the closest definition is a strike being a pitch “struck at by the batter.” This lack of clarity means it is up to umpires’ judgment to determine if a batter has struck at the pitch. Traditionally, a check swing is considered complete if the batter breaks an unofficial plane—though what constitutes that plane is also undefined.

Why Replay Review Was Not Used

Despite advancements in replay technology and the introduction of the Automated Ball-Strike (ABS) system this season, check swings remain outside the scope of reviewable plays. The expanded MLB replay rules allow managers to challenge calls such as force and tag plays, as well as certain aspects of fan interference, but not check swings. As a result, the Rays were unable to challenge the decisive call that ended Game 2. Fox play-by-play announcer Joe Davis remarked during the broadcast, “We need to get a system that can get [check swings] right.”

Technological Advances and the Check Swing Challenge

In response to situations like this, MLB has been exploring technological solutions. In 2024, the league tested a check swing challenge system in the Arizona Fall League using Hawk-Eye technology, enabling teams to review whether a check swing crossed a 45-degree threshold from home plate. Since then, the check swing challenge has expanded to the single-A Florida State League in 2025 and the triple-A Pacific Coast League in 2026.

When Will the Check Swing Challenge Reach the Majors?

MLB Commissioner Rob Manfred addressed the possibility of bringing the check swing challenge to Major League games, noting the need for teams to adjust to the ABS system first. In June 2025, Manfred stated, “We do try to think sequentially about what’s coming... We got to get over the hump in terms of either doing ABS or not doing it before you’d get into the complication of a separate kind of challenge involved in an at-bat.” No definitive timeline has been set for implementing check swing challenges at the Major League level.

Looking Ahead

With the Brewers now two wins away from their first championship and the spotlight on ambiguous rules and technology in baseball, the Game 2 check swing controversy has reignited discussions about how MLB can continue to modernize its officiating and replay systems. As technology progresses, players, managers, and fans alike will be watching closely to see if checks like Díaz’s can be reviewed in future Fall Classics.
