Span has been out since last Sunday with an injured shoulder, stemming from an awkward dive in center field. Span has been taking swings in the cages and is throwing, but still isn't quite ready to return. Monday appears a more likely target date to be back in the lineup.
"He says it's feeling better, moving in the right direction," Twins assistant general manager Rob Antony said. "He hopes to hit on the field [Saturday] and then we'll go from there."
Revere, who rolled his ankle trying to beat out a throw at first base on Wednesday, is closer to being back on the field. He was available off the bench on Saturday and there is a good chance he'll make his return to the lineup on Sunday.
"Revere feels better [Saturday]," Twins manager Ron Gardenhire said. "He still has some bruising and swelling in his ankle. He's available if I need him in the ballgame and a possibility he'll play [Sunday]."
With Span and Revere out, Darin Mastroianni started in center field and Matt Carson got the start in right. Second baseman Jamey Carroll batted leadoff for the first time this season in their absence.
