Will Ospreay will return to AEW Grand Slam Mexico for the second straight year, but this time in his first-ever singles match at Arena Mexico. Ospreay will take on former friend/partner and rival Mark Davis after the now-former National Champion issued the challenge on AEW Dynamite in a backstage promo. The other new match announced will feature AEW Women’s World Champion Willow Nightingale and the Brawling Birds against Mercedes Mone and AEW Women’s Tag Team Champions Divine Dominion in a trios match. Nightingale will defend against Mone at All In and it’s assumed Divine Dominion will defends their titles against the Birds on that same show.
