The Toronto Blue Jays have claimed right-hander Cesar Valdez from the Oakland Athletics and designated right-hander Mat Latos for assignment.
Valdez was optioned to triple-A Buffalo and right-hander Neil Ramirez was activated from the Bisons before Friday night's game at Tampa Bay.
Latos, who made his big-league debut in 2009 with San Diego, was 0-1 with a 6.60 earned-run average over three starts with Toronto.
He signed a minor-league deal with the Blue Jays in February and was called up last month when starters J.A. Happ and Aaron Sanchez suffered injuries.
