The Oakland Athletics claimed right-hander Marcus Walden on Wednesday after he was put on waivers by the Toronto Blue Jays.
Walden was designated for assignment by the Blue Jays a day earlier. He made five appearances for Toronto in spring training but did not play in a regular-season game.
The 25-year-old native of Fresno, Calif., was 6-14 with a 3.71 earned-run average last season at double-A New Hampshire. Walden made three appearances at triple-A Buffalo this year, going 0-1 with a 13.50 ERA.
