When the New York Mets turned to MJ Melendez last month, they were desperate for a spark. The team was mired in a brutal 12-game losing streak, and their season was quickly slipping away. Facing the Los Angeles Dodgers on the road, Melendez was thrust into the lineup—and he delivered immediately, ripping two doubles and driving in a run against none other than Shohei Ohtani. While the Mets lost that game 8-2, Melendez has since become one of the few bright spots in a lineup that has struggled to find consistency.

Since that debut, Melendez has been hitting in the heart of the order, an unexpected role for a player who was cast off by the Kansas City Royals. In a recent game against the Colorado Rockies, he added a triple, a walk, and a check-swing single that drew a classic remark from Mets legend Keith Hernandez on SNY: "When you're hot, you're hot." That lucky hit is emblematic of Melendez's current hot streak—a run that has seen him post a staggering .912 OPS and a 158 wRC+ in just 16 games as a designated hitter and outfielder. Those numbers blow away his career averages and have provided a much-needed lift for a Mets team that has been plagued by injuries and offensive inconsistency.

But the big question remains: can he keep this up? The Mets entered the season as preseason playoff favorites with an enormous payroll, but a deep hole in the standings has made every game critical. Asking a reclamation project like Melendez to help carry the lineup is a tall order, but he insists he's ready for the pressure. "It's really cool to have that so-called pressure," Melendez told the media in late April. "I think it's something that you either love or you hate. I feel like I love that kind of thing."

Melendez's journey to this point has been anything but smooth. Drafted by the Royals in 2017, he was ranked as the No. 42 overall prospect by Baseball America when he debuted in May 2022. He was a league-average hitter as a rookie, but his production declined over the next two seasons. After spending most of 2025 in Triple-A, the Royals declined his option, giving him another shot in the majors. So far, luck has been on his side: Melendez is the second luckiest hitter on the Mets, with a .458 BABIP that trails only Austin Slater's .556 (though Slater's number is inflated by just 12 plate appearances). His .398 wOBA versus a .271 xwOBA suggests that he's finding ways to produce, often with a lucky bounce or two.

Whether Melendez can sustain this level of production remains to be seen, but for a Mets team searching for any kind of spark, his hot bat has been a welcome surprise. In a season full of challenges, he's proving that sometimes, the most unlikely sources can provide the biggest boost.
