Perez was traded to the Rays on Thursday and assigned to Triple-A Durham, Marc Topkin of the Tampa Bay Times reports.
Perez had spent the first portion of the season in the Astros' organization, slashing .267/.298/.385 with nine steals in 52 games with their Triple-A affiliate. The 26-year-old does have some big league experience in his career and could eventually earn a call up to the majors to help provide relief to an injury-plagued Tampa outfield.
