KANSAS CITY, Mo. — There are homecomings and there are home-run comings.

Luke Voit put on a Show Me State exhibition for his loyal fans in his home state. Voit blasted a 470-foot, two-run home run to left field in the seventh inning Saturday at Kauffman Stadium to break a 3-3 tie and boost the Yankees to a 7-3 win over the punchless Royals in the first game of a doubleheader.

The Yankees rode that wave to a sweep with a 6-5 win in the nightcap.

That 470-foot calculation was a Statcast guesstimate. Voit thought the blast went deeper into orbit.

“To come here and probably hit the farthest home run I ever hit, it was pretty surreal,’’ Voit said. “I was on Cloud 9 that at-bat. I felt like it was longer, but 470 is pretty good. I don’t know if you can really hit them farther than that.’’

This one was special.

“I got drafted by these guys out of high school, and it’s pretty cool to come back here being in the Midwest and my wife is on the patio in front of 60 people out there, so it was pretty cool for family and friends and guys I played with in college,’’ Voit said.

The home run was the 13th of the season for the slugger who grew up 225 miles from Kauffman Stadium in Wildwood, Mo., and was drafted in the 32nd round by the Royals out of Lafayette High School in 2009. He did not sign and was drafted in the 22nd round in 2013 by the Cardinals, who gifted him to the Yankees last year.

Brilliant trade for the Yankees. Dreadful for the Cardinals.

Voit has been one of the biggest reasons the Backup Bombers own a 34-17 record. He gives them swagger, and not in just the way he walks around the clubhouse in muscle shirts.

After high school Voit attended Missouri State University in Springfield. Voit had quite the contingent of 60 people on the right-field patio. They went bonkers with his blast. He said he was trying to hit a home run to right, but he’ll take 470 to left after a recent adjustment he made where he noted he had been opening too early with his back hip.

“My swing foot was kind of messed up,’’ Voit said. “I was coming around everything. I’m over sliders, under fastballs. More like I was guessing, instead of seeing the pitches. I wasn’t being myself.’’

He was back to himself with that swing. Party on!

“It was exciting,’’ Voit said of having such a large contingent of fans at the game. “It’s fun to do it here and in front of family and friends.’’

Voit hit the ball so far he forgot to do the Voit Hop.

Voit is one of the best stories in baseball this season, finally earning a full-time starting position at the age of 28. That was the 27th home run he has hit since coming over from the Cardinals on July 29.

In many ways he has saved this Yankees team with Aaron Judge, Giancarlo Stanton and Didi Gregorius injured.

“I still haven’t been in a lineup yet, outside of the playoffs, with Judge, Stanton, Didi and Gary [Sanchez], all of them,’’ Voit said. “So I am super anxious for those guys to get back because I might be able to see a little more fastballs.’’

Kauffman Stadium is where he had his original pre-draft workout. He played a couple of games here with the Cardinals but this was his first home run here and the crowd of 25,243 let out a rousing “Luuukkeee!’’

“This is the funnest team I’ve played on for sure,’’ Voit said. “Everyone calls us the Baby Bombers so I feel like someone will hit a home run or drive in a run with a big hit.’’

Welcome home-run, Luke.
