Outfielder Fernando Martinez was one of four players re-assigned to the minor-league camp after last night's 3-1 victory over Cleveland.
"It's a happy day,'' Martinez said. "They gave me a chance to play, and I learned so much.''
Randolph said Martinez made a positive impression.
"Of all the young kids we brought to camp, he was the one I wanted to see most, and he didn't disappoint,'' Randolph said. "He has a chance to be a pretty good player and be a big part of our future.''
Also sent to the minor-league camp were pitchers Tony Armas, Nate Field and Joselo Diaz.
