That's when Benito Serven turned the game over with a three-run homer, and Oakland kept swinging. The board flipped fast enough that DraftKings' pregame number on this one — an Astros team favored at home — was already ancient history by the middle innings. Houston still had the better roster on paper walking in; the roster didn't show up when it mattered.
Max Muncy put an exclamation point on it in the seventh with a go-ahead solo shot, and from there it was about outs, not runs. Houston never got another crooked number on the board after the fourth, stranding chances against an Oakland bullpen that had barely been used all series.
For a last-place Athletics club playing out the string at 50-80, taking this series from a team fighting to stay over .500 is a nice, if inconsequential, notch. For the Astros, it's the second gut-punch weekend in a row — they were run out of their own building 18-3 by the Angels just days earlier, and Sunday's blown lead reads like the same team that's been finding new ways to lose.
Houston's lineup is already without Carlos Correa and Brice Matthews for extended stretches, and thinning depth showed up in exactly the spot where a 6-run cushion should have been safe. A club still clinging to a share of a playoff picture can't keep giving away leads like this one and expect the standings to cooperate.
