Otto Wallin, the main event in the upcoming "Day of Reckoning" heavyweight card on December 23 in Saudi Arabia, has shared his prediction for the Deontay Wilder vs. Joseph Parker bout. This event promises a spectacular end to the 2023 boxing calendar, featuring high-profile matchups such as Anthony Joshua vs. Wallin, Jarrell Miller vs. Daniel Dubois, and Dmitry Bivol vs. Lyndon Arthur. The Wilder vs. Parker showdown adds extra intrigue, showcasing two former world champions with Parker's camp expressing confidence in a knockout victory. Wilder, known for his powerful right hand, contrasts with Parker's versatile boxing-fighting style, having faced elite heavyweights like Joshua, Dillian Whyte, and Joe Joyce. Despite Parker's active year, securing three wins, Wallin sees Wilder as the favorite. Wallin suggests that Parker's activity might pose a challenge for Wilder, who has had limited in-ring time over the past two years. In a statement to TalkSport, Wallin advises Parker to adopt an aggressive strategy, drawing insights from Parker's recent bout with Joshua. Wallin emphasizes the importance of Parker taking the fight to Wilder, avoiding a scenario where staying on the outside might lead to a knockout.
