WASHINGTON -- Chicago Cubs third baseman Kris Bryant and Washington Nationals outfielder Bryce Harper are working together to help the victims of the Las Vegas shooting that left 58 dead and nearly 500 injured Sunday night.

Harper and Bryant, both Las Vegas natives, shot a PSA on Thursday that aired during Game 1 of the National League Division Series between their respective teams.

"The biggest thing is, Vegas is very small," Harper said after filming the PSA. "If you were born and raised there, you know everybody. You know who this person is on this side of town or that side of town. Relatives, friends, whatever. So when something happens like this, it's going to hit home."

Bryant and Harper both knew people who attended the Route 91 Harvest Festival but escaped with less than life-threatening injuries.

"You don't want to see it happen to your hometown, but it's been amazing to see the people in the community come out and help," Bryant said. "I don't know if I've ever seen a response like that. People wanting to help other people. It shows that even in a time like this there are good people out there."

Added Harper: "Nurses, doctors, first responders, medics ... they're working 70 hours straight. That's how it is when you're from there. You want to lend that hand as much as you can."

Harper and Bryant believe the Major League Baseball playoffs are a good time to publicize what Las Vegas is going through, and they are hopeful people around the country will help.

"In the NLDS, and the platform we have, the PSA was an easy thing to do," Bryant said. "We wanted to help out in any way we can. People are going to be struggling for a long time -- just as they are after the hurricanes. You see this country coming together. Whatever we can to get people to support, we're ready to do."

Reaching out as a duo was Harper's idea. They may be foes on the field, but before and after games, Bryant and Harper are two high-profile guys from Las Vegas trying to help a city recover from an emotional moment.

"I was wondering what we can do from afar," Harper said. "It's tough. You want to go down there and help out. ... We just want to get the word out and have people provide even a dollar to whatever organization you want. It all counts."
