ARLINGTON, Texas -- The Rangers expect to get a big boost to their lineup Friday at St. Louis when first baseman Mitch Moreland comes off the 15-day disabled list.

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."
