On Saturday, Cabrera was out of Cleveland's starting lineup due to tightness in his left hamstring. Acta said the All-Star shortstop is considered day to day with the injury, but the Indians are not sure when he will return to the field.
"We don't have a timetable for it," Acta said prior to Saturday's game against the White Sox. "We'll have a better idea tomorrow when he shows up to work."
Cabrera tweaked his hamstring while making a play in the field during Friday's 9-3 loss to the White Sox, while making his 31st consecutive start at shortstop for the Indians. Through 39 games this season, the switch-hitting Cabrera has hit at a .301 clip with five home runs, 14 doubles, 20 RBIs and 23 runs scored.
With Cabrera out of the lineup on Saturday, Acta gave the nod to 23-year-old shortstop Juan Diaz, who was promoted from Double-A Akron prior to Friday's game. Diaz replaced Cabrera in the field in the seventh inning of Friday's game and then struck out in his first Major League at-bat in the eighth.
The Indians initially recalled Diaz to have an extra infielder on hand for a few days while third baseman (and backup shortstop) Jack Hannahan worked through a minor back injury. Hannahan returned to the lineup as the Indians' third baseman on Saturday.
