Bryce Harper broke the Fanatics record for most jerseys sold within 48 hours, according to ESPN's Eddie Matz.
Harper's No. 3 Phillies jersey outsold LeBron James' Lakers jersey and Giancarlo Stanton's Yankees jersey on the online retailer's website. Khalil Mack and Jimmy Garoppolo round out the top five Fanatics jerseys with the Bears and 49ers, respectively.
Harper wore No. 34 with the Nationals during his seven-year stint in Washington. He chose to switch numbers with Philadelphia to honor the late Roy Halladay, who died in a plane crash in November 2017.
