The Diamondbacks will place speedster Tim Locastro on the injured list after today’s ballgame, per Steve Gilbert of MLB.com (via Twitter). Locastro jammed his finger at second base while getting caught stealing for the first time in his big league career, notes Nick Piecoro of the Arizona Republic (via Twitter). He had been successful in his first 29 stole base attempts, a Major League record to start a career.

The Diamondbacks will be down to their third-string centerfielder when Locastro joins Ketel Marte on the shelf. Rookie first baseman Pavin Smith took over in center for the remainder of today’s game in Washington. The Diamondbacks are flush with versatile defenders, from Josh Rojas to Andy Young to Wyatt Mathieson, Smith, and Asdrubal Cabrera. Unfortunately, none are particularly suited to centerfield. Catcher/outfielder Daulton Varsho could be a consideration, as could the newly-acquired Nick Heath.
