"There was some frustration involved, and that's it," Angels manager Mike Scioscia said of the ejection.
Escobar, who had a career-high 13-game hitting streak snapped Saturday in Baltimore, entered play Sunday hitting .321, tied for seventh in the American League. Second baseman Johnny Giavotella replaced Escobar, with Gregorio Petit shifting from second base to third.
It was Escobar's third ejection of the season and No. 12 of his career.
