Canha was sent down to Triple-A Nashville on Friday.
Canha has been struggling mightily at the plate recently, going just 2-for-29 with 17 strikeouts over his past 10 games and hitting .191/.234/.393 with three home runs and seven RBI on the season. He will be replaced by Jaycob Brugman and heads back to Nashville for the first time since early May. If Canha can rediscover his groove at the plate, he is likely to return to Oakland at some point this summer.
