The Pirates recalled Valdez from Triple-A Indianapolis on Thursday.
Valdez went 2-for-16 with a pair of home runs during an earlier stint in the big leagues this season. The Pirates could give Valdez regular chances in the outfield while they deal with the fallout of the Oneil Cruz's absence due to a hand injury. Valdez, 22, has slashed .255/.388/.526 with 13 home runs across 237 plate appearances with Indianapolis this season.
