The Diamondbacks have acquired infielder Adam Rosales from the Athletics for right-hander Jeferson Mejia, the clubs announced Monday.
The deal comes as the result of news that Arizona shortstop Chris Owings fractured his middle finger Sunday, and utility man Ketel Marte tragically lost his mother to a car accident Monday morning. Rosales provides infield depth for the NL Wild Card leaders, as he's played second base, third base, and shortstop for the Athletics in 2017.
Rosales, 34, has an uninspiring .234/.273/.346 slash line in 223 plate appearances this season, but he'll serve as a short-term replacement in the starting lineup until Marte and/or Owings are ready to return.
For the time being, infielder Brandon Drury, who has a 93 OPS+ in 339 PAs this season, will likely slot back into the lineup at either second base or shortstop. While the Diamondbacks are lacking middle-infield depth, they're strong at the corners with All-Stars Jake Lamb at third base and Paul Goldschmidt at first base.
Mejia, 22, was acquired by the Diamondbacks with Zack Godley in 2014 in a package deal that sent Miguel Montero to the Cubs. Working strictly as a reliever in 2017, Mejia has a 5.90 ERA, 1.793 WHIP, and 10.9 K/9 in 29.0 innings between Single-A and Hi-A. The Dominican-born righty signed with the Cubs in 2013, and did not rank on either MLB Pipeline or Baseball America top-30 prospect lists.
