I think the Marlins will make it to the playoffs via the wild card. They're currently on a 5-game win streak and have a consistent offense and a rotation with upside that finally has started to shine these past few weeks with Hand, Alvarez, and Turner. Eovaldi and Koehler have the stuff but falter with command issues. Now, with Miami playing the way that they are, the team will probably be buyers at the Deadline to bolster the rotation as their General Manager, Dan Jennings, has stated that they will not be sellers. They have no needs offensively or defensively. They already covered the second base issue with the Valdespin/Solano combo. If they go after a Tommy Milone or Ian Kennedy, I think they're well suited to make a run for it.
Mariners or Blue Jays or Yankees. Although I don't know if the Yankees count as a "sleeper team" being they make the playoffs almost every year. But they way they're playing this year I think should qualify them as one.
Yes, it's possible a sleeper team will make the playoffs.
Question: "Sleeper team to make the playoffs?"
You're correct - "...sometimes people just don't use their minds on here."
The Mets
At least one every year.
mariners or mets
