Martinez (elbow) will be activated prior to Wednesday's game against the White Sox, Matthew Mowery of the Oakland Press reports.
Martinez, who has been sidelined with an elbow injury since mid-June, will make his triumphant return Wednesday against lefty Chris Sale. He hit .278/.316/.361 with 11 strikeouts during an eight-game rehab assignment. The elbow injury could prevent him from hitting for his usual power numbers over the rest of the season, but there should still be enough production for him be used in all formats upon his activation.
