The San Diego Padres will promote Franmil Reyes before Monday's game against the Colorado Rockies.

They have an open roster spot after designating Chase Headley for assignment on Saturday.

Reyes, 22, was signed out of the Dominican Republic in 2011. An unheralded prospect, Reyes has hit well in the Pacific Coast League. He's hitting .346/.440/.748 with 14 home runs over 150 plate appearances.
