The Rangers have placed first baseman Mitch Moreland on the 15-day disabled list with a strained right hamstring, the latest in a series of injuries to key players this season, after an MRI exam performed Thursday in Texas showed a strain that could keep Moreland out up to a month.
The Rangers have purchased the contract of Triple A first baseman Chris McGuiness, who is expected to be at Fenway Park for the series finale Thursday. To make room for McGuiness, right-hander Colby Lewis has been placed on the 60-day disabled list.
Moreland was injured Wednesday night in the seventh inning while running to second base with a leadoff double. He said he felt the hamstring tighten after rounding first base.
Moreland was removed from the game in favor of Jeff Baker, who scored one of the two runs on Elvis Andrus' tie-breaking double three batters later.
The Rangers are already without second baseman Ian Kinsler, who has been out since May 18 with a stress reaction in is ribcage, and they are cautiously watching third baseman Adrian Beltre, who missed games Sunday and Tuesday with a strained left hamstring. Andrus has been dealing with a sore back for nearly two weeks.
McGuiness will be making his major-league debut. He was the MVP of the Arizona Fall League last year and was returned to the organization in late March after he failed to make the Cleveland roster as a Rule 5 pick. McGuiness was hitting .275 with six homers, 19 doubles, 34 RBIs and a .382 on-base percentage in 55 games with Round Rock.
