Moss-Carter duo pivotal to A's resurgence

OAKLAND -- Much has been made of the A's revived offense, and rightfully so.

It's a big reason why the team is in contention in September following a mediocre first half, and much credit goes to the powerful platoon stationed at first base.

Oakland has utilized several platoons over the course of the season, yet none has worked out as well as this one, with Chris Carter and Brandon Moss splitting time at first.

Together, Carter and Moss have combined for 30 home runs and 68 RBIs. All other A's first basemen -- notably Daric Barton and Kila Ka'aihue -- managed four home runs and 12 RBIs, while hitting just .200 overall.

"It's too bad we can't have two DHs or two first basemen to get them both in the lineup," manager Bob Melvin said. "They've both been swinging the bat very well. It's an easy and a difficult decision to put one of them in there on a particular day. Easy in the fact you expect one to perform, and difficult in the fact they're not both in there.

"As long as one doesn't sit for an extended period, you feel like you give them enough at-bats to keep them current, and they're feeling good about it. We try to make sure we get them in there, best matchups."

Worth noting

• Brandon Inge will undergo season-ending right shoulder surgery on Sept. 13 in Michigan. Dr. Stephen Lemos will perform the procedure. Inge is expected to return to the team shortly thereafter to offer support through the remainder of the season.

• Lefty reliever Jordan Norberto (shoulder) has yet to resume throwing, but manager Bob Melvin said on Wednesday he's hopeful that time will come in the next few days.
