Josh Hamilton, who was unable to play the last two games of a scheduled three-game minor league rehabilitation assignment because of discomfort in his surgically repaired left thumb, is to be evaluated Monday by doctors and athletic trainers in Seattle.
The Angels left fielder, who hasn't played since April 8, was jammed by a fastball in his last at-bat with triple-A Salt Lake Thursday night and was unable to play Friday or Saturday.
Hamilton was originally scheduled to be activated for Monday's game against the Mariners in Safeco Field.
Manager Mike Scioscia said the initial reports on Hamilton indicated "soreness" and that there is not a concern that the slugger tore the ligament. Scioscia remained hopeful that Hamilton would be able to resume his rehab assignment this week.
