Haggerty left Monday's intrasquad game after his first at-bat with hip soreness, Greg Johns of MLB.com reports.
Manager Scott Servais said that the injury is nothing serious. Haggerty remains a likely candidate to make the Mariners' Opening Day roster over fellow utility options Jose Marmolejos and Dylan Moore. The 26-yera-old has just four major-league at-bats and was claimed off waivers by Seattle this offseason.
