Punto set to return from hamstring issue

SAN FRANCISCO -- A's infielder Nick Punto is expected back in the A's lineup Friday, barring any further issues with his left hamstring.

Punto experienced tightness in the hamstring during Monday's game and has since been held out of game action. But after undergoing a full set of workouts Friday afternoon, manager Bob Melvin said he's good to go.

Punto is expected to start at second base against left-handers when the season begins, as part of a rather strict platoon at the position with Eric Sogard. But the switch-hitting Punto, an excellent defender, is likely to see plenty action off the bench in the later innings on any given day.
