CHICAGO -- The D-backs picked up some added middle-infield depth Monday by acquiring Adam Rosales from the A's in exchange for Minor League right-hander Jeferson Mejia.
In addition, the D-backs placed infielder Chris Owings on the 60-day disabled list with a fractured right middle finger.
Rosales gives the D-backs some coverage at shortstop after Owings was injured Sunday and Ketel Marte was placed on the bereavement list Monday due to the death of his mother. In addition, Arizona is without the services of shortstop Nick Ahmed, who is out until late August with a fractured right hand.
Rosales has played 55 games at short for the A's this year, along with eight at second, four at third and one in left while compiling a .234/.273/.346 slash line in 223 plate appearances.
With the Padres last year, Rosales had a career high OPS of .814 while also hitting 13 home runs. He has an .809 OPS against left-handed pitching over the past two seasons. The D-backs have struggled against lefties this season.
Mejia, 22, was acquired by the D-backs on Dec. 9, 2014, from the Cubs in the trade that sent catcher Miguel Montero to Chicago. He was a combined 1-1 with a 5.90 ERA in 21 games with Class A Hillsboro and Class A Kane County this year.
