MIAMI -- The process of bonding -- from a safe distance, of course -- is underway for the Marlins as they opened Summer Camp on Friday at Marlins Park.

Two workout groups practiced at different times at the ballpark, keeping with social-distancing guidelines recommended by MLB and health officials.

“We’re making sure we were within the protocols and keeping guys socially distanced and using the whole facility,” Marlins manager Don Mattingly said. “Taking advantage of every inch of the facility.”

As one team looking to build a winning culture, the Marlins are getting back into playing shape by keeping their distance from each other. That includes a limited number of players in the clubhouse at the same time.

In fact, the team is using the home and visiting clubhouses at the ballpark to make sure everyone is safely spaced.

Indoors, the players wear masks. On the field, they don’t, because they’re going through baseball drills.

The retractable roof at Marlins Park was partially opened, and the sliding glass wall beyond left and center fields was open, providing plenty of ventilation.

Not yet full squad
On Summer Camp's first day, about 25 players worked out at Marlins Park. That number is expected to grow on Saturday, because the COVID-19 test results for more players will be available.

Those cleared to play will be back on the field.

Mattingly acknowledged that some in the organization have tested positive for COVID-19. An exact number isn’t being revealed, but a few days ago, it was reported that a player and a staff member had tested positive for the virus in early June.

“We haven't had to send anyone home,” Mattingly said. “You have to pass the guidelines to be able to come to the ballpark. We're still waiting on results to come back from our players.”

Player, staff responsibility
South Florida is one of the areas in the country that has seen a spike in COVID-19 cases, which increases the challenge for the Marlins as an organization to keep players and staff safe, especially away from the ballpark.

“We've got to encourage our guys about if they want to run around at night,” Mattingly said. “These are things we have to have discussions about.”

Mattingly on leadership
The return of MLB comes at a time the nation and world are dealing with the coronavirus pandemic and racial injustice issues.

As a manager, Mattingly noted he has a responsibility as a leader to his players.

Away from the field, Mattingly’s foundation, Mattingly Charities, supports programs for athletic, educational and social development for underserved youth in Evansville, Ind.

“For me, leadership is about being yourself,” Mattingly said. “Being honest with guys. Preparing and getting better.

“The issues and things that have come up really fit comfortably for me. My foundation has been a foundation that is working within the inner city, for the most underserved kids and families, to bring equality. I'm really comfortable in that area.”
