Rex and Brody Reinhart, the two young boys believed to have been killed by their father this week, were elite youth baseball players known across the region for their passion about the sport. It defined their short lives.

Teammates, coaches and parents of players – along with the boys’ family members in Gainesville – have mourned their loss since the boys’ deaths Tuesday. Their mother, Minde Reinhart, 42, has been a fixture at ballfields across Florida cheering for her sons. The two had played since they were very young.

Brody, 11, regularly an unofficial batboy for the No. 10-ranked University of Florida baseball team, was seen by tens of thousands of fans at games returning bats to the home dugout after a hit. Rex, 14, was a dominant pitcher in his age group, coached on a travel team by former Major League star Gary Sheffield, 52, of Tampa, who admired his tenacity.

Through her grief, Minde Reinhart posted her first tribute to her sons on Facebook this week: “No words describe what I feel. But knowing they loved every second of life and baseball will keep their memories alive.”

A day later, she published a photo of both boys in their baseball uniforms, adding: “My babies!! #theywilllivewithmeforever.” Nearly 800 people quickly responded.

What happened:Two Florida boys killed by their father in apparent murder-suicide, authorities say

Eerie parallels:Man suspected of killing young sons, himself mirrors case of brother who killed ex-wife’s boyfriend then attempted suicide

More:Paul Reinhart texted ‘You’re going to live with this the rest of your life’ to his wife. Hours later, he and his sons were dead

Baseball permeated the boys’ lives, cementing friendships even with rival players across Florida. The family is close friends with Florida coach Kevin O’Sullivan, who lives a short walk from their home. A painted mural on a city wall in Gainesville to honor the boys this week included baseball seams. When Brody delivered a book report in school, he chose a text about Willie Mays.

Players and their parents from across the United States, including Georgia, Mississippi and New Jersey, have offered sympathies and condolences for the loss of the brothers.

In an online tribute, Rex’s team, the Florida Heat, highlighted his talents on the field, his likability and his iconic look with his flowing, black hair curling from beneath a batting helmet.

“Rex made an immediate impact on the team and in the lives of his teammates, both on and off the field,” the team said in a statement. “He was kind, generous, funny, talented, and a bit of a fashion icon with his flow and sunglasses. His loss is profound and we are reeling.”

The vehicle of an investigator from the Alachua County Sheriff's Office is parked May 4 outside the home of Paul O. Reinhart, 46, of Gainesville, after Reinhart was suspected of killing his two young sons and then himself at the family's vacation home 50 miles away in Cross City. One of Reinhart's sons, 11-year-old Brody, was regularly a bat boy for the No. 10-ranked University of Florida baseball team.

A rival player of Brody in Tallahassee, Brayden Smith, 11, said the two met after a game about 18 months ago. During a break between games, they found an open field and played a spontaneous pickup football game. They became fast friends and afterward communicated by Snapchat and text,
