None of that has moved a market yet — there's no line posted on this one as of now, days out. That's normal for a game still 3 days away, but it also means whatever price eventually goes up will have to account for a health situation on both sides that's still writing itself by the hour.
Arizona still holds the NL's final Wild Card position as of the most recent standings, and that's the frame for everything the Diamondbacks do the rest of the way — every game between now and October either tightens their grip or hands it to San Diego. They took 1 of 3 from Philadelphia and are coming off a loss to Houston, and they've got two more against the Astros before this series even opens, so whatever record they carry into Kansas City on paper right now isn't the one that walks off the team plane. Kansas City, meanwhile, is squarely in call-up season — the front office has already started rotating arms and outfielders through with an eye on 2027, which tells you everything about where this club's head is.
Arizona and Kansas City open this series Monday, September 7, so nothing about how that game goes is settled here — this preview is about the game after it. What is settled: the Royals' bullpen has taken real hits, with Carlos Estevez headed for season-ending shoulder surgery and Nick Mears already done for the year, on top of Beck Way being shut down. For a last-place team playing loose, that's the kind of pen that can turn a saveable seventh inning into a track meet — which cuts both ways for whoever's chasing a comfortable night against them.
