Nationals right-hander Taylor Jordan, White Sox catcher Josh Phegley and Braves first baseman/outfielder Joey Terdoslavich have all made their Major League debuts in the last 10 days, necessitating they be replaced on the U.S. roster. Cole, McCann and Walker will fill their spots.
Riefenhauser takes the place of Rays right-hander Taylor Guerrieri, who is experiencing shoulder fatigue. Galindo replaces Cardinals outfielder Oscar Taveras, who is on the disabled list with a high ankle sprain.
Cole is ranked No. 76 on MLB.com's Top 100 prospect list. He was a key piece to the trade that brought left-hander Gio Gonzalez to Washington, and he was then reacquired by the Nationals in the Michael Morse deal in January. Cole is 5-3 with a 4.58 ERA and has struck out 98 batters in 88 1/3 innings at Class A Advanced Potomac this season.
McCann is ranked as the Tigers' No. 11 prospect by MLB.com. Detroit selected him in the second round of the 2011 First-Year Player Draft, making him the club's first pick that year. This season, he is hitting .287 with three home runs at Double-A Erie.
Walker is ranked No. 16 on the Orioles' Top 20 prospect list. He began the season at Class A Delmarva, where he hit .345 with a .412 on-base percentage in 31 games. Since being promoted to Class A Advanced Frederick in mid-May, Walker is hitting .287 with seven home runs in 50 games.
Riefenhauser, the Rays' 20th-round selection in the 2010 Draft, has moved quickly through the Minor Leagues. He began the season with Double-A Mobile and was recently promoted to Triple-A Durham. Between the two levels, Riefenhauser has compiled a 0.64 ERA and 52 strikeouts in 56 1/3 innings this season.
Galindo, a native of Venezuela, is hitting .272 with 37 stolen bases at Class A Augusta. He is the second Venezuelan on the World roster, joining Orioles left-hander Eduardo Rodriguez.
