In 2018, reflecting the long-standing Yankees–Red Sox rivalry, Wally's Twitter account showed a video of him blasting the Red Sox victory anthem "Dirty Water" from his radio at Fenway following the Game 4 road victory of the Red Sox at Yankee Stadium, in a sort of revenge for Aaron Judge playing the Yankees' victory anthem "New York, New York" there following their Game 2 road victory days before. When the Red Sox swept them Yankees earlier in the season, Wally went on the field post-game with a broom. In 2019, Wally took a photo with Jennifer Lopez, who is engaged to former Yankees player Alex Rodriguez, and tweeted a photo at him. During the 2019 London Series, both Rodriguez and Wally posted a photo to social media accounts of Wally “strangling” Rodriguez.
