Canha was brought back up to the majors prior to Wednesday's game in San Francisco.
Canha has spent 29 games with the big-league team this season, hitting .191/.234/.393 with three home runs and seven RBI. He was optioned to Triple-A Nashville in early June while in the midst of a slump, but Canha's been seeing the ball much better in the minors, going 49-for-167 while slugging .545 since heading back down. He figures to provide depth in the outfield and at first base going forward.
