PHOENIX -- The D-backs scratched Jason Kubel from their lineup before Sunday's 1-0 loss to the Padres due to a stiff back.
"Just going through all the stretching, it tightened up," said Kubel, adding that no MRI is scheduled at this point. "Hopefully [Monday's] day off will help. Hopefully, it feels better."
The 31-year-old went 1-for-4 with a double on Saturday and was initially slotted to bat fifth and man left field Sunday before getting pulled. In his place, A.J. Pollock got the nod in center field and Adam Eaton shifted to left.
Kubel, who missed two weeks in April with a strained quad, is in the midst of a down year, batting .234 with just five homers and 27 RBIs.
