Worth noting

• The A's claimed outfielder Kenny Wilson off waivers from the Blue Jays on Monday and optioned him to Triple-A Sacramento. They also outrighted outfielder Nick Buss to Sacramento.

Buss had been designated for assignment Saturday to clear a 40-man roster spot for Samardzija.

• A's Minor League outfielder Herschel "Boog" Powell has received a 50-game suspension without pay after testing positive for an amphetamine in violation of the Minor League Drug Prevention and Treatment Program.
