The Oakland Athletics activated outfielder Ben Copeland from the disabled list and then recalled him from Triple-A Sacramento before Tuesday's game against the Los Angeles Angels.
The A's optioned left-hander Dana Eveland, who figured to be a mainstay in the starting rotation, to Sacramento.
Copeland, a Rule 5 pick from the San Francisco Giants, was informed of the move earlier Tuesday.
"It was a full load," Copeland said. "I still had all my stuff from spring training, my fiancee and her sister in the car."
Copeland sustained whiplash on the left side of his neck when he ran into the outfield wall chasing down a fly ball in spring training.
A .282 career hitter in the minor leagues, Copeland will be making his major league debut.
Eveland is 1-2 with a 7.20 ERA in six appearances including five starts.
"We need to get him into the rotation to work on a few things," A's manager Bob Geren said of Eveland. "He needs to work on his command."
