In addition to Helton and Tracy, Michael Cuddyer, Eric Young Jr., Matt Belisle, Josh Roenicke, Christian Friedrich, Jordan Pacheco, Josh Rutledge, Rex Brothers, Drew Pomeranz, Adam Ottavino and Mike Ekstrom visited the victims at the University of Colorado Hospital.
Four of the five patients the team visited remain in critical condition, including 22-year-old Farrah Soudani, who remains in intensive care.
"It brought tears to her eyes," Mike White, Soudani's boyfriend, told the Denver Post. "They cheered her up. They told her to stay strong. ...
"We just want to say thanks, not just to the Rockies, but to everybody who has given the victims so much love and support."
The Rockies' contingent also toured the emergency room and thanked doctors and nurses that helped in the aftermath of the shooting.
The Rockies arrived in Denver at roughly 3 a.m. Thursday morning after playing in Arizona. A notice was posted on the clubhouse message board asking for volunteers from the team to meet with victims.
"It was a simple matter of a memo on the board and this was the result," Tracy told the Post. "We would have had a heck of a lot larger group -- heck, we might have had the whole team -- but because we were going to be in the ICU, we had to limit our numbers.
"I think this shows you what kind of character these guys on our team have, and how much they care about the community."
The shooting at the suburban Denver movie theater on July 20 left 12 dead and 58 injured.
