The A's placed infielder Nick Punto on the 15-day disabled list Sunday, a day after he strained his right hamstring scrambling to get back to third base in the fifth inning against the Kansas City Royals.
First baseman Nate Freiman was recalled from Triple-A Sacramento, the club announced in a statement.
Punto was batting .207 in 64 game for the A's. Freiman hit .212 over a 14-game stint for the 's from June 29-July 26. At Sacramento he is batting .284 with 15 home runs and 74 RBI in 80 games.
