It marks the second straight year that both Ricketts and Shults will compete for the U.S. National Team, as the tandem guided America to its fifth straight World Cup of Softball title last year.
Ricketts went on to help the team win gold at the Pan American Games last fall.
The USA Women's National team is slated to participate in six different events in the United States and Canada this summer.
Four of those will be available to fans in the United States, including a pair of exhibition events and the Title IX 40th Anniversary Celebration Game against Canada June 23 and the World Cup of Softball VII presented by Lumber Liquidators June 27-July 2, in Oklahoma City.
Following the World Cup, the Women's National Team will compete at the Canadian Open Fast Pitch International Championship in Surrey, B.C., Canada, July 4-9, and July 13-22 at the International Softball Federation (ISF) Women's World Championship in Whitehorse, Yukon, Canada.
Two other Sooners, first baseman Lauren Chamberlain and center fielder Destinee Martinez, were part of the team selection camp and will play on the USA Elite Team that is set to participate in a series of exhibition games over the course of the next six days in Summersville, W. Va, and Ashland, Ohio, on June 14 and 18, respectively.
