In addition to those killed in the fire, 13 others were hospitalized in what the Houston Fire Department has called the deadliest fire in its 118-year history.
"Our prayers go out to the families and friends of the firefighters who lost their lives or were injured in last week's tragedy," Astros president Reid Ryan said in a statement. "We all owe a debt of gratitude to all of our firefighters, who risk their lives to keep others safe."
The Astros are also offering free tickets for this week's games (Tuesday through Thursday) for local and national firefighters and their immediate family members at the Minute Maid Park Box Office, with a firefighter ID.
