The Toronto Blue Jays acquired right-hander Arnold Leon from the Oakland Athletics on Tuesday in exchange for cash considerations or a player to be named later.
The 27-year-old reliever made his big-league debut with the Athletics last season, going 0-2 with a 4.39 earned-run average over 19 appearances.
He had a 2-5 record and 2.95 ERA over 20 appearances (six starts) with triple-A Nashville last year. Leon was designated for assignment last week when Oakland finalized its contract with Henderson Alvarez.
Leon also pitched for Mexico at the 2013 World Baseball Classic.
