Christian Walker Returns to D-backs Lineup as Lourdes Gurriel Jr

Walker rejoins the team after a month-long absence, while Gurriel's calf strain sidelines him for at least 10 days.

Walker had been out since July 29 due to a strained left oblique muscle.
He was hitting .254 with 23 home runs before his injury.
Gurriel was placed on the 10-day IL with a left calf strain, retroactive to September 2.
Gurriel has a .274 batting average with 17 home runs this season.
The D-backs are currently in the second NL Wild Card spot and third in the NL West.
