The San Francisco Giants placed outfielder/ first baseman Aubrey Huff on the 15-day disabled list on Friday with a sprained right knee.

Huff, who has already missed significant time this season due to anxiety problems, suffered the injury while celebrating Matt Cain's perfect game on Wednesday.

Huff is hitting just .155 with one home run and five RBI in 32 games for the Giants this season.

To fill the vacant roster spot, the team recalled infielder Justin Christian from Triple-A Fresno. He is in the lineup for Friday's game against the Seattle Mariners.
