Nate Freiman is expected to miss the next few games as he's dealing with a strained muscle in his abdomen. The rookie first baseman has done a very nice job in a platoon role with the A's this season, slashing .275/.329/.392 with 10 homers and 24 RBI in his 189 at-bats, primarily against left-handers. Look for him to return to the lineup early next week.
