HOUSTON — No chance in hell.

Or, there’s a first time for everything.

When it comes to the 115th World Series the first cliché is a wise bet, because in the previous 114 the visiting team has never won all seven games.

So, after the Astros dropped the first two games to the Nationals at Minute Maid Park they went to Washington and turned the Nationals’ bats to goo during a three-game road sweep.

That’s five-for-five for the road grays heading into Game 6.

Tuesday night inside Minute Maid Park, the Astros, who lead the best-of-seven series, 3-2, get the first of possibly two cracks at being crowned World Series champions. But a Nationals victory would set up on Wednesday the best moment in sports: a Game 7.

A victory would give the Astros a second World Series title in three years. If the Nationals find a way to recover from a disastrous weekend in the nation’s capital they would win the first title in franchise history.

And while the chances of the Astros winning one of two are greater than the Nationals stringing together two victories on the road, it’s not like the NL champions are bringing a bayonet to a nuclear war.

Stephen Strasburg starts for the Nationals and Justin Verlander goes for the Astros in a rematch of Game 2 in which Strasburg outpitched Verlander in a 12-3 Nationals victory that left the Astros down, 2-0, and for dead by many.

Strasburg, who could be pitching his final game with the Nationals since he can opt out of his contract, didn’t pound the drum for the marquee pitching matchup against Verlander, who is 0-5 with a 5.73 ERA in six World Series starts.

“It’s an American League game. So he’s obviously not going to be getting in the box. What he does against us is really irrelevant to what I have to focus on, and that’s their lineup and finding a way to keep them at bay,’’ said Strasburg, who gave up two runs and seven hits in six innings in Game 2.

Pick a reason for the Astros’ resurgence. Some believe an informal talk among the players following Game 2 helped. George Springer said the off day between Games 2 and 3 provided the chance to exhale and reset mentally. Josh Reddick said the 8-1 Astros win in Game 4 provided a wake-up call that the bats were alive.

Yet, the most credit goes to the Astros’ pitchers. Or, the most blame falls on the Dead Bat Society with the script “W’’ on their hats, who went a horrific 17-for-97 (.175) and had one hit in 21 at-bats (.048) with runners in scoring position in Games 3-5.

“When I look back, we’re missing our pitches. I want us to be a little bit more aggressive on the fastballs. Also, we’re facing some really good pitchers. So it’s imperative that — it’s tough enough to hit with two strikes, but you’ve got Gerrit Cole on the mound and you’re hitting with two strikes, it gets tougher,’’ Nationals manager Dave Martinez said Monday at Minute Maid Park. “With that being said, I want these guys to just relax and just try to stay in the middle of the field and put the ball in play. So just keep working good at-bats. This will turn around. Like I said, one guy gets on, walk, whatever, the next guy, and just keep that train going.’’

That train Martinez wants to roll hasn’t run out of track yet.
