PEORIA, Ariz. (AP) - Infielder Matt Tuiasosopo has been optioned to AAA Tacoma by the Seattle Mariners.
Seattle also reassigned catcher Adam Moore, right-hander Sean White and catcher Jason Phillips to its minor league camp on Thursday.
Tuiasosopo had an impressive spring training, hitting .404 with seven doubles and a pair of home runs, and his improved defense at third base caught the attention of manager Don Wakamatsu.
Moore, among the Mariners' top prospects, appeared in 11 spring training games. But his playing time figured to decrease following the return of Kenji Johjima from the World Baseball Classic.
