There was a something special about the two-run homer by David Ortiz on Friday night, and not just because it helped the Boston Red Sox beat the New York Yankees, 4-2.

Ortiz made a video with former teammate Kevin Millar before the game and in it shared a promise to a sick child that he would hit a home run.

After the game, Millar, now an analyst for MLB Network, shared a series of posts on Twitter about the story behind the home run. He first shared a picture of a young boy named Maverick Schutte, who he said “battles for his life daily and is a big Red Sox fan.” He then posted a video that he and Ortiz sent to Maverick before the game.

“Always stay positive, keep the faith,” Ortiz said in the video. “You take care buddy. And I am going to hit a home run for you tonight.”

Maverick is a 5-year-old Red Sox fan from Wyoming who was born with a serious congenital heart defect called tetralogy of fallot. He has undergone more than 30 surgeries and likely will need to undergo many more, according to the Colorado Children’s Hospital Foundation.

Millar also posted a response from Maverick from after the game.

“Big Papi, you never let me down,” Maverick said. “You are the best player ever in the Red Sox game. And I’m trying the hardest to get out there at Fenway Park and meet you.”

On Friday night against the Yankees with the score 2-2 in the bottom of the eighth, Ortiz turned on a curveball and delivered the homer, rounding the bases and hugging Millar’s children on his way back to the dugout.

“After I hit the home plate, when I’m walking to the dugout and I saw Millar and his kids, I don’t know if you saw how excited I was but that was when I started thinking about it,” said Ortiz.

Manager John Farrell said “the legend of Ortiz is far-reaching.”

Ortiz reflected on the moment Saturday.

“Yesterday, Millar pulled me into the room and he was like, ‘Hey, there’s this friend of mine, they have a child who was having problems and he’s probably not going to make it so I want to send him a video because he loves you,’ ” Ortiz said. “We did that video and towards the end, I said I was going to hit a home run for him.

Ortiz said he’s promised home runs three times and hit one each time.

“I would say this is just God putting his hands on things like that, because we all know it’s not easy to come through like this,” Ortiz said. “We all know I’ve been able to get things done like that, but I have been able to get things done like that on a few occasions. I guess I’ve been lucky. You know, I would say God is the one who took over this.”

Ortiz could barely believe he came through.

“Listen, it’s not like, how can I explain this to you?” he said. “It’s not a guarantee. This is baseball. This is not, ‘Hey, I’m going to shoot a free throw when nobody is playing defense on you,’ or, ‘I’m Stephen Curry and I’m going to hit a 3-pointer.’ Stephen Curry can shoot a 3-pointer and you know it’s going to happen, regardless. This is baseball.

“But what you’re trying to do, that video, what I was trying to do was make Maverick feel happy and have that connection with him. You throw that out there just to make sure he has a friend he can count on right here.”
