Heriberto Hernandez powered a one-out walk-off grand slam in the bottom of the ninth to complete a sweep of the New York Mets in Miami, as the Mets slipped to 22-31 and Heriberto Hernandez’s rare power moment turned into a brutal ending.
The ninth inning started with a scoreboard problem for the Miami Marlins. By the time Heriberto Hernandez took the swing that mattered, the Mets weren’t just trailing anymore—they were out of options.
With the game scoreless heading into the bottom of the ninth, New York went to closer Devin Williams. The plan didn’t survive the first pitch that turned into contact. Hernandez smashed a walk-off grand slam with one out to win it for Miami and finish a sweep of the Mets in Miami.
Hernandez hadn’t been a regular power threat coming into the game. Before Sunday, he had just one homer in 99 plate appearances. Even so, he delivered in the exact way that changes a season narrative. He reached on an infield single in the seventh inning. but he didn’t score then—so the timing of what he did next made the moment sting even more for New York.
Williams’ outing also wasn’t close to what he’d been doing recently. This was a brutal reversal after a run of dominance. The Mets closer had gone ten consecutive outings without allowing a run. and he credited a pitch-tipping change to his re-found success. On Sunday, those adjustments didn’t hold. He was tagged for one of the ugliest possible outcomes: 0.1 innings, two hits, four earned runs, and two walks.
The result carried more weight because New York had a chance to make itself feel better after a tough stretch—an opportunity to salvage an important series against a division rival. Instead. the Mets walked out of Miami swept by a Marlins team that’s up and coming. and now the damage shows up in the standings.
The Mets dropped to 22-31, leaving them in the basement of the NL East. They could have passed Miami this weekend, but they didn’t. Williams. brought in after a dismal run with the Yankees and then turning things around. now has another chapter to explain—one that ended not with a late save. but with a grand slam that wiped out the Mets’ chance to avoid the sweep.
Aaron Judge and Colton Cowser had helped make it a Sunday full of walk-offs early across MLB. with both going deep to win games. In Miami. though. the story belonged to Hernandez—one homer before Sunday. and then a walk-off grand slam in the bottom of the ninth that turned the Mets’ closer’s moment of momentum into a late-inning collapse.

Dude Williams really just got cooked on one pitch? Mets bullpen is cursed for real.
Wait so it was scoreless till the 9th and then a grand slam with 1 out?? That’s insane. I swear scoreboard glitches always happen when stuff is about to go wrong lol
They say it’s a pitch-tipping change that was working for Williams… but then it didn’t. So basically Miami stole signs again? That’s what it sounds like. Also Mets were already bad so whatever, but walk-off slams feel personal.
I don’t even get why they kept bringing in Williams if he had that many bad outings lately. Like wasn’t he just terrible with the Yankees? Seems like they set themselves up. And now they’re ‘in the basement’… maybe the Marlins pitchers just timed Hernandez because he only had one homer??
