Though he will sometimes give Andre Ethier the day off against left-handers he has trouble against, Dodgers manager Don Mattingly said he's "definitely not going to platoon him."

Ethier is a career .238/.296/.352 hitter against left-handed pitching, but Mattingly is committed to playing his $85 million outfielder every day. Of course, it helps the outfielder's cause that the Dodgers don't really have any good options as potential platoon partners.

According to Ken Rosenthal and Jon Paul Morosi of FOX Sports, the Mariners were recently in touch with the Dodgers about a possible trade for Andre Ethier.

Talks failed to progress, so there will be no deal. Rosenthal and Morosi were told that one other AL team inquired about Ethier, but the identity of the club isn't known. On a potentially related note, CBS Sports' Jon Heyman reported Thursday afternoon that the Red Sox were told at the start of the winter that Either was "unavailable."

Ken Rosenthal of FOXSports.com reports that the Dodgers have "zero intention" of trading Andre Ethier.

CBS Sports' Jon Heyman confirms that the Dodgers aren't shopping Ethier and haven't received any offers. However, Rosenthal notes that two American League teams have expressed interest, and GM Ned Colletti likely wouldn't be opposed to moving him in the right deal. Ethier has $85 million remaining on his five-year contract extension and is signed through 2018.
