Oakland Athletics left-hander Lenny DiNardo will miss a couple of days after straining his left Achilles tendon.

A's manager Bob Geren said Tuesday that the 30-year-old felt something while throwing a day earlier and will be held out of drills for the next two days.

DiNardo, who last won a major-league game in April 2008 while with the A's , signed a minor-league contract in January and was invited to spring training as a non-roster player.

He's spent parts of the past five seasons with the Boston Red Sox , Oakland and the Kansas City Royals .
