There were also gray shirts with pictures of vegetables surrounding Randall Delgado, with the words Mr. Organic above him.
"I think it's just signs of a team with a lot of chemistry and a lot of fun," Bradley said. "Doing stuff like this, kind of spontaneous to support each other, to back each other. Coaches love it, we love it, guys love it. It's part of the culture we have building here. It just shows the fun that we have together. We're so much more than teammates off the field, and it really shows with little things like this."
The Bradley shirt is available in the team shop at the ballpark.
"The only rule is, he can't wear it," said Bradley's in-season roommate, Jake Lamb.
The Delgado shirt is a players-only shirt and was the brainchild of shortstop Chris Owings, who also came up with the David Peralta Freight Train shirts last season.
"We're with each other so much that there's a lot that goes into every single day," Owings said. "Just some stuff that's happened throughout the last couple seasons has brought some ideas up."
Said Bradley, "I have to imagine there's going to be many more in the works as the season continues."
Reliever Silvino Bracho was recalled from Triple-A Reno for the fifth time this year on Saturday. He takes the place of outfielder Jeremy Hazelbaker, who was optioned to Reno after Friday night's game.
With Delgado making a spot start Sunday, the team wanted to add another arm to its bullpen.
Pollock to play
Outfielder A.J. Pollock (strained right groin) is expected to play Sunday for Reno. Pollock was pulled from a game Monday with tightness in his right quad.
"I spoke to him today by phone and he is very encouraged by how he's feeling," D-backs manager Torey Lovullo said.
Lovullo would like to see Pollock get at least 10 at-bats before activating him.
