Marlins vs Astros (07.21 09:10, Minute Maid Park)

Starters: Marlins Janson Junk / Astros Ronel Blanco

On paper the Marlins have the edge, sixth in the NL at a 52% win rate, ahead of the Astros 47% mark that has them tenth in the AL. But the recent form tells a different story: Houston's four-game skid is bad enough, yet Miami's current slide has stretched to six straight losses, so neither club is exactly rolling into this one.

The starting pitching picture is lopsided in terms of available data. Janson Junk's last five outings are all on the board, and his FIP over that stretch (5.46) is actually worse than his season ERA (4.57). Outside of a solid five-inning, one-run start on July 10, he has had a couple of rough nights allowing eight earned runs apiece in the past month. Ronel Blanco, on the other hand, has no recent velocity readings or last-five-game data showing up at all, so his current form is essentially a blank slate here.

Both lineups are also still unconfirmed for today, so there is room for late changes once they are locked in. Offensively, both sides have cooled off lately but Miami more sharply, their season average of .267 has dropped to .214 over the last five games, while Houston's dip from .254 to .237 has been milder. The bullpen picture favors Houston too, with a 3.63 ERA well ahead of Miami's 5.54, so even with the standings tilted toward Miami, this one sets up as a reasonable spot for the Astros at home.
