Ginni Rometty joins Condoleezza Rice and Darla Moore as the third female member at Augusta National, according to Golf Digest.
The magazine reports that IBM's chief executive officer was seen last week at the club taking swings.
"She has a nice swing," Golf Digest quotes one member who saw Rometty on the driving range. "She's obviously got a big job so she doesn’t play much, but if she got to play, she'd be a pretty good golfer."
Augusta National nor IBM would confirm Rometty's membership.
Under pressure to change its 80-year history as an all-male club, the home of the Masters Tournament added former Secretary of State Rice and Moore, a South Carolina financier and philanthropist, as its first female members in August 2012.
Augusta National had been criticized for excluding Rometty, who became the computing giant's first female chief in 2012, from membership. IBM has sponsored the Tournament for more than a decade and its previous CEOs have been historically invited to join the ranks.
Rometty, 55, holds a 35.4 handicap at a course nead IBM headquarters in New York, according to Golf Digest.
