Gage Jump to A's Rotation?

As I posted on X/Twitter today, the A's have yet to announce their probable starter for Sunday's game. That spot would typically go to Jacob Lopez, following J.T. Ginn on Saturday. 

Before this revelation, I wrote about Gage Jump's most recent start on Wednesday, where he dominated for seven scoreless innings. I also mentioned that the spot to keep an eye on in the rotation would be Lopez's. 

That said, with Jump's start on Wednesday, he wouldn't be quite ready to slot into the rotation on Sunday, as that would be his fourth day, not fifth. This is certainly a situation to keep an eye on in the coming days. 

Given the timing factor, what move would you be making here, if in fact Lopez is out in the rotation.
