Rodriguez said that he would talk with reporters at Camden Yards on Friday afternoon following the meeting, adding that he "can't wait."
A supermarket tabloid reported last month that Rodriguez was involved in a high-stakes illegal poker game in Beverly Hills, Calif., in 2009, although a source later indicated that Rodriguez had not actually been at the event in question.
Rodriguez was warned by MLB and the Yankees in 2005 to avoid such activities.
Following the publication of the article, MLB issued a statement that read, "We take this very seriously and have been investigating this matter since the initial allegation. As part of the investigation, the Commissioner's Office will interview Mr. Rodriguez."
