Daniel Murphy went from NLCS superstar to World Series villain — all in one play Saturday night.

And it only got worse in Sunday night’s season-ending 7-2, 12-inning loss to the Royals in Game 5 of the World Series.

Murphy made another error in that decisive 12th, this time on a Paulo Orlando grounder to extend an inning that was already spiraling out of control.

“I didn’t play as well as I wanted to,” Murphy said of his disastrous World Series performance. “That’s most certainly the case. I wish I was able to swing the bat better. I wish I was able to make a couple more plays, but I can’t get that back now. It’s unfortunate.”

And as he heads into free agency for the first time, Murphy doesn’t know where he’s going to end up.

“That’s down the road,” Murphy said. “I’m not sure what next year is going to look like. I’ve enjoyed my time here. This organization has been great to me. I love the guys. … I’ve been in this organization since 2006. That’s a long time.”

He likely made himself extra dollars in the early rounds of the playoffs, and the Mets could go with low-cost Dilson Herrera next season at second base if they don’t splurge on Murphy.

“I like it here, and I’d like to come back,” said Murphy, who added he wouldn’t necessarily go to the highest bidder. “We’ll have to see. I’ll make plenty of money [anywhere].”

That’s true, but if he leaves, he will undoubtedly be remembered for the error on Eric Hosmer’s grounder that allowed the tying run to score in what ended up being a crushing loss in Game 4 on Saturday.

After hearing his name chanted by the Citi Field faithful earlier in the Series, Murphy was booed several times Sunday as he was unable to steady himself defensively.

That changed in the 12th, and when Hosmer grounded out to Murphy for the second out in the inning, the Queens crowd cheered derisively after turning on him.

Before the game, Terry Collins defended the NLCS MVP once again.

“Well, it was a chopper,” the manager said of the play that will remain in the minds of Mets fans. “He thought he had to hurry. I think that’s what happened. Eric can run. Dan charged it and he just didn’t get the glove down as low as he needed to.”

And just like that, the seven postseason homers — including a home run in six straight games — were all but forgotten.
