But a decision he made also had plenty to do with it.
After clearing three rounds of auditions in Season 5 in 2013, Worthington, 18, was rejected by the judges. So he went home.
"I wasn't going to do it again, because I felt like I had already had my chance, and I felt like there was a big life out there, with grown men and women singing for a living, while having to live in their cars," he says. "And I felt they needed the opportunity, not some redneck kid still in high school. But then, I thought, 'Why not me?'"
In May, Worthington finished second in the competition. He and eight others from the show will perform Thursday in Fort Lauderdale.
Worthington describes himself as a hog farmer from a small town near Houston, and says he is enjoying the tour, which began Saturday and will conclude Aug. 2.
"We all hang out together, do everything together," he says. "It's just a damn good time."
His best moment so far, he says, was singing with the group Alabama during the TV show.
"It was probably the most nerve-racking moment ever, but it was a great experience," Worthington says. "Who the hell gets to sing with Alabama? I mean, come on."
Soul singer Josh Kaufman, who defeated Worthington in the finals, headlines the show. Dia Frampton from Season 1 will appear, as will Jake Barker from the most recent season. Barker's audition of Bruno Mars' "When I Was Your Man" has collected more than 2.5 million hits on YouTube.
A signature red judge's chair also will be on site for fans to plop down on and act like Blake Shelton.
The Voice Tour will arrive 7:30 p.m. Thursday, June 26, at the Broward Center for the Performing Arts, 201 SW Fifth Ave., in Fort Lauderdale. Tickets cost $35 to $140. Call 954-462-0222 or go to BrowardCenter.org.
