Grove will start Game 1 of Tuesday's doubleheader against the Diamondbacks, Juan Toribio of MLB.com reports.
Grove will get at least one more turn through the rotation after also facing Arizona in his last spot start Sept. 14, though he's likely to serve as more of an opener Tuesday before Ryan Pepiot takes over, per J.P. Hoornstra of the Los Angeles Daily News. Grove found success in his first showing against the Diamondbacks, surrendering two runs on two hits and one walk while fanning four over five innings of work.
