Per The Athletic's Ken Rosenthal, Harper will meet with Padres officials on either Thursday or Friday in Las Vegas.
Per Fancred Sports' Jon Heyman, Harper's meeting with the Padres will happen on Friday. The Chicago White Sox, Washington Nationals and Philadelphia Phillies are among the teams known to be interested in the 2015 National League MVP.
Rosenthal added Harper and/or his agent, Scott Boras, have had meetings with "a number of" teams recently, but there is no indication any deal is close.
The Padres are emerging as a late player in the free-agent sweepstakes for Harper and Manny Machado.
One factor that could work in San Diego's favor is money to spend. The team currently has MLB's sixth-lowest payroll ($74.2 million). The team also has a wealth of talent in the minors, including 10 players in MLB.com's top 100 prospects list for 2019.
Harper's free agency has been an ongoing topic throughout this offseason. The 26-year-old made his sixth career All-Star appearance in 2018 after hitting .249/.393/.496 with 34 homers and 100 RBI for the Nationals.
