The Yankees had previously acknowledged some of the signings during the winter. Diaz and Rivera -- a former Yankee who started his career with New York from 2001-03 -- will have strong chances to make the team as a right-handed outfield bat, while Wilson is pegged to serve as Triple-A insurance behind the plate.
New York's list of spring invitees also includes two of the club's first-round Draft picks: outfielder Slade Heathcott (2009) and shortstop Cito Culver (2010).
Additionally, two players named on MLB.com's Top 100 prospects list have also been invited to camp: catcher Gary Sanchez and outfielder Tyler Austin.
The Yankees will also give a close look to right-hander Mark Montgomery, who could help in the big league bullpen at some point this season. Mason Williams, the club's top outfield prospect, did not receive an invitation to big league camp.
In all, the Yankees have invited 20 pitchers, six catchers, nine infielders and nine outfielders to camp as non-roster players. The Yankees had just 67 total players report to camp in 2012, 17 fewer than this year.
