Even Matt Williams, who was dismissed by the team as third-base coach earlier in the week, came to show his support, as did Rockies shortstop Trevor Story and members of the Arizona Cardinals and Phoenix Suns.
The event, which took place at Lucky Strike in downtown Phoenix, raised money for Goldy's Fund 4 Kids, which was started by Goldschmidt and his wife, Amy, in 2014 to help raise money to help kids and families at Phoenix Children's Hospital.
The Goldschmidts have volunteered at the hospital since Paul came to the big leagues in 2011 and have stepped up their efforts over time. They are the honorary chairs of the "Hope Lives Here" campaign to help raise awareness and money for the hospital's new Center for Cancer and Blood Disorders.
"It's really cool," Goldschmidt said. "We've been able to help out in a small way over there and provided books and DVDs and video games and all that type of stuff and go over and kind of brighten some kids' and some families' days. Hopefully, [Thursday] we'll raise some more awareness about the new center for cancer and blood disorders and the needs of Phoenix Children's Hospital."
Also in attendance were recently hired D-backs general manager Mike Hazen and manager Torey Lovullo.
It was the first time that Goldschmidt met the two.
"I'm sure we'll kind of get to know each other probably more in Spring Training than anything," Goldschmidt said. "They've got a lot of work they're doing. My main focus is just taking care of myself and getting ready.
"I don't really know much about them, but heard great things. I got texts from guys in the Red Sox organization, other organizations, saying, 'Hey, you're going to love the two new guys, Torey and Mike.'"
