OAKLAND -- David Ortiz made history Wednesday, but it wasn't enough make the Red Sox winners.
Ortiz smacked his 400th career homer in the fourth inning, but the Red Sox were swept by the Oakland A's, pinned with a 3-2 loss. Boston finished it's seven-game road trip with a 2-5 mark against two teams (Oakland and Seattle) with losing records.
Aaron Cook pitched into the seventh inning, but was saddled with the loss. Coco Crisp tripled to right-center to start the inning and rode home with the go-ahead run when Andrew Miller allowed a single to left to Jemile Weeks through a drawn-in infield.
The Sox mustered just three hits on the afternoon while suffering their first sweep here since 2008.
Other than the solo homer by Ortiz, the only other Red Sox run came in the seventh when Ortiz walked, took second on an error by Weeks and scored on a single to center by Adrian Gonzalez. Gonzalez's hit extended his hitting streak to 15 games, but represented his first RBI on the trip.
Brandon Moss homered off Cook in the second -- his second of the series against his former team -- and scored the second run when Brandon Inge doubled him home in the fifth.
