Chalmers shot 6-under-par 64 on Thursday to tie Jeff Klauk for the lead after the first round of the Milwaukee tournament.
"I've played in several opposite-field events and it typically provides a fantastic story for someone if they're not a named player," Chalmers said. "It could be a first-time winner, it could be someone who goes from nowhere to somewhere very quickly.
"People talk about the great stories, the Tiger Woods, the Phil Mickelsons and all the top players, but sometimes some of the best stories are about the guys who are battling away and manage to find a week where they strike gold."
