Moreland, who has been out since June 5 with a strained right hamstring, completed a three-game rehab assignment Wednesday with Double-A Frisco and worked out with the Rangers before Thursday's game against Oakland.
"I'm ready to go," Moreland said.
Moreland crushed Double-A pitching his last two games on Tuesday and Wednesday, going 6-for-9 with a home run, three doubles and three RBIs.
"He did what he should do against that young pitching," Rangers manager Ron Washington said. "Eat it up."
Moreland was one of the Rangers' hottest hitters when he pulled up lame going for a double on June 5 against Boston at Fenway Park. He was batting .333 with 10 home runs and 25 RBIs in 41 games before the injury. Moreland was third in the American League with a .561 slugging percentage and 10th with 12 home runs.
The Rangers' offense slumped without Moreland and second baseman Ian Kinsler, who returned from the disabled list on Saturday.
The Rangers as a team have averaged 3.3 runs per game and have batted .235 without Moreland. The Rangers went through a six-game losing streak last week in which they scored eight runs.
