Christian Walker returns; Lourdes Gurriel Jr. to injured list

SAN FRANCISCO — The D-backs got some mixed injury news ahead of Tuesday’s series opener against the Giants at Oracle Park, activating slugging first baseman Christian Walker from the 10-day injured list but losing outfielder Lourdes Gurriel Jr. to a left calf strain.

Walker had been out since sustaining a left oblique strain on July 29 against the Nationals. The two-time Gold Glove Award winner was hitting .254 with an .814 OPS before being sidelined for all of August, and his 23 homers are tied with Eugenio Suárez for second most on the team behind Ketel Marte’s 30.

Gurriel was placed on the 10-day IL, retroactive to Monday, with a left calf strain. The veteran outfielder had suffered some tightness in his left calf muscle on Sunday afternoon while trying to avoid a double play in the bottom of the sixth inning. As he ran to first, Gurriel started to pull up a bit and was noticeably limping.

Gurriel had been set to undergo imaging on his calf once the team arrived in San Francisco in order to determine the severity of the injury, manager Torey Lovullo said. The team has not announced the results of the imaging.

Gurriel has slashed .274/.316/.428 across 125 games for the D-backs this season while primarily playing in left field.
