The statistics don’t deceive, and going by them, it was not Aaron Boone but umpire Laz Diaz the real culprit on Monday night at Chicago’s Guaranteed Rate Field. The home plate umpire in the Yankees-White Sox game had a woeful performance in determining balls and strikes, triggering a major outburst from manager Aaron Boone.

Aaron Boone was thrown out by Diaz during the eighth inning when he stepped onto the field to express his protest. The manager’s comical reaction attracted headlines and widespread fan reaction. However, this couldn’t absolve Diaz of his error-prone umpiring.

Umpire Auditor shared the following astonishing statistic on Twitter after the game:

“Umpire Laz Diaz missed 21 calls in the #Yankees #WhiteSox game and 14 went against the Yankees. He had a lower correct call rate than Angel Hernandez did on Sunday.”

Umpire Auditor reported that Angel Hernandez’s accuracy suffered on 23 occasions during the Yankees’ 9-7 defeat against the Astros on Sunday, further solidifying his position as “the umpire with the lowest accurate call rate in the league.”

Returning to Diaz, who became the primary target of Aaron Boone’s frustration on Monday evening. A comprehensive analysis by Umpire Scorecards reveals that Diaz accurately judged 89% of the pitches taken.

Among the 166 pitches he called, Diaz had 19 instances of inaccuracy. This marked 8.6 fewer correct calls compared to the average umpire, as per Umpire Scorecards. His count of 19 missed calls shared the rank for the 13th-highest this season. Additionally, out of the 50 called strikes, 17 were inaccurately identified as balls, resulting in Diaz’s called strike accuracy registering at 66 percent. In contrast, the standard MLB average is 88 percent. This definitely provoked Aaron Boone.

Diaz forced Aaron Boone to react

Aaron Boone eventually reached his breaking point in the eighth inning when Anthony Volpe was called out on strikes on a close decision during the 5-1 loss. The Yankees manager vehemently expressed his displeasure against Diaz, leading to Aaron Boone’s ejection from the game, followed by a humorous impersonation of the umpire’s gestures by the manager.

This incident occurred a single inning after DJ LeMahieu faced a similar situation in the top of the seventh, with runners on first and third and one out, as he was called out on a pitch that was visibly outside the strike zone. As per the Umpire Scorecard analysis, the LeMahieu strikeout stood out as the most significant incorrect call of the match, having the greatest impact on changes in run expectancy.

Aaron Boone stooped down and traced a line in the soil with his finger at the boundary of the left-handed batter’s box, illustrating his perception of the pitch’s location. He then theatrically imitated Diaz’s forceful strike-three gesture.

Aaron Boone expressed his frustration, noting that he was ejected for the 32nd time in his managerial career. He emphasized the abundance of questionable pitch calls throughout the entire game. In the eighth inning, Aaron Boone was ejected by Laz Diaz following a heated dispute.

This marked Aaron Boone’s sixth ejection of the season, making him the leader in this category within the American League.

At least the Yankees can claim the top position in something.

This incident might also result in Aaron Boone facing his second suspension of the season, given his previous outburst over ball and strike calls in a game against the Orioles back in late May.

Aaron Boone claims support from MLB managers

The fervent ejection of Aaron Boone garnered appreciation from his fellow MLB managers. According to the Yankees’ skipper, he received messages from “a good number” of his counterparts following his demonstration of drawing a line in the dirt close to home plate and imitating umpire Laz Diaz’s strikeout signal during Monday night’s away game against the Chicago White Sox.

Aaron Boone chose not to disclose the specific comments made by other MLB managers, but he noted that the feedback was filled with humor. He mentioned that Laz had signaled for him to continue, implying that he felt somewhat provoked to “go make a fool of yourself.” He noted that he followed through with it.

Following Monday’s statement where Aaron Boone attributed the exchange to his growing frustration with several calls, he revealed on Tuesday that he felt his emotional outburst had caused embarrassment to his daughter, Bella. Aaron Boone expressed his discomfort with engaging in such actions.

The Yankees manager mentioned that he believed it was necessary to advocate for his perspective on the events unfolding in the game.

Alex Cora of the Boston Red Sox mentioned that he had a conversation with Boone on Tuesday and shared with the media that he found amusement in Boone’s imitation of Diaz. The Red Sox manager commented on the imitation, saying, “That was quite impressive.” He also mentioned that he shared with Boone that his mimicry of the hips was particularly accurate.

Yankees manager Aaron Boone admitted feeling uncomfortable with his dramatic actions, emphasizing his reluctance to engage in such behavior. Nonetheless, he believed it was essential to address the unfolding situation in the game.

Aaron Boone also disclosed that he had a conversation with MLB Senior Vice President of On-Field Operations Mike Hill on Tuesday, choosing to keep the specifics of their talk private.
