"I told him I want to play," Cabrera said.
Acta said he wanted to make sure his star shortstop wasn't trying to be a hero in May. After Cabrera assured Acta his tight hamstring was feeling better, Acta added Cabrera to Tuesday night's lineup as the designated hitter. He batted third against the Royals, singling in his first at-bat.
Cabrera left Friday's game at Chicago with the hamstring injury, and missed the next three games.
"He's pain free," Acta said. "He ran the bases well and he was very adamant that he has no issues whatsoever."
Acta said he expects Cabrera to start at shortstop on Wednesday. Entering Tuesday, Cabera was hitting a team-best .301 with five home runs and 20 RBIs.
Travis Hafner (knee) and Carlos Santana (concussion) remained out of the lineup for Tuesday's game. Hafner took batting practice on the field Tuesday afternoon, but Acta said Hafner's still not 100 percent with his running.
"I anticipate having him available off the bench if I need him," Acta said.
Santana was cleared to begin doing cardio activities, and Acta said he continues to make progress. Santana is eligible to come off the seven-day concussion list this weekend.
