The Star-Spangled Banner was performed by trumpet.
For the day, the Marlins wore a special cap, with a camo design on their team logo.
Logan Morrison belted a special home run in Miami's 5-3 win, and when he approached the plate, he saluted to the sky in honor of his father.
Morrison's father, Tom, passed away in December 2010. He was formerly in the Coast Guard.
"I try to keep the emotions in check, and try not to do too much at the plate," Morrison said. "I wasn't even thinking about it when I hit the home run, but when I was crossing the plate, absolutely. It was pretty cool.
"I had goosebumps going around the bases. Giving him a salute was pretty cool."
As an organization, the Marlins have actively supported the military. In recent years, players and team representatives have traveled around the world to visit the troops.
During the season, the Marlins have their "Outback Steakhouse Military Mondays" promotion. The team offers complimentary tickets for military employees, active duty and retirees, Reserve, National Guard and their dependents.
