U.S. captain Mardy Fish announced his roster on Monday, with the Bryan brothers joined by Taylor Fritz, Reilly Opelka and Tommy Paul in the best-of-five series in Honolulu on March 6-7.
"I want to keep the momentum going for sure," he said. "It's a new surface, and that's important even though I did have a successful grasscourt season for the most part. It's all hardcourts from here on. Confidence is a huge part of tennis. I feel extremely confident right now."
