The Diamondbacks have selected infielder Jesus Valdez to the big league roster, per a team announcement. He’s been optioned to Double-A. Valdez will serve as the club’s 27th man for today’s game against the Padres.

Arizona and San Diego were permitted to add an extra man for the Mexico City series, but it had to be a position player. After initially declining to make an addition to the roster, the Diamondbacks made the move for the second game of the series. An injury to shortstop Geraldo Perdomo led to the decision, per Nick Piecoro of the Arizona Republic. Perdomo went down with an ankle injury yesterday. The issue isn’t expected to require an IL stint, Piecoro relayed in a separate post.
