"I didn't get to see it," he admitted. "My dad saw it and he told me, and my buddy texted me."
Roberts was getting the feel of a new glove on Saturday, one given to him by D-backs third-base coach Matt Williams a day earlier.
"It feels awesome," he said. "It's honestly one of the best gloves I've ever put on."
Williams broke in the glove throughout Spring Training, and passed it on to Roberts after the 30-year-old inquired about the model number for a new web.
"He ended up saying, 'Why don't you use it, check it out,'" Roberts said. "I used it today, and he said I could have it if I wanted. It worked out perfect."
But Roberts doesn't have any immediate plans to ditch his current glove just yet.
"I've used it going on three years now," he said. "The comfort level I have with that, I can't trade gloves just yet."
