Josh Hamilton to miss Seattle series

SEATTLE -- The Rangers will be without Josh Hamilton this weekend in Seattle. The outfielder returned to Texas on Friday for tests on his blurred vision, and the team decided to keep him there through the weekend.

The warning signs came before Thursday's series finale against the Angels. Manager Ron Washington said Hamilton was falling off balance while taking grounders. He then had trouble judging fly balls, and that was the last straw.

"Once we saw that, we got him off the field," Washington said. "We aren't messing with that."

Doctors have not identified a clear cause for the symptoms.

Adrian Beltre also will miss Friday's game against the Mariners, but should return to the lineup Saturday.

Beltre, who has been battling intestinal issues, missed Wednesday's game against the Angels but persuaded Washington to let him play Thursday. It paid huge dividends, as the All-Star belted a go-ahead, two-run homer in the ninth inning.

Beltre saw a doctor in Los Angeles on Friday morning and underwent gastrointestinal tests. The team said he is feeling better and is scheduled to arrive in Seattle late Friday night. Washington decided to give his third baseman some rest and have him ready to go Saturday.

Hamilton has not played since coming out of the lineup partway through Tuesday's loss to the Angels. He said the symptoms have been a result of a sinus infection that affects his balance and vision.

Washington's level of concern for the All-Star outfielder hasn't wavered since Tuesday.

"We're just trying to do everything we can do to ease his mind," he said. "Once he has a peace of mind with what's going on, we'll be fine with Josh."

Hamilton is hitting .287 and entered Friday leading the American League with 42 home runs.
