He also led the league in runs scored (41), hits (67), total bases (111) and walks (34), and was third in home runs (12) and fifth in runs batted in (34).
It means the Cavalry now has their two offensive stars from the 2011-12 campaign back at the plate again, with Kody Hightower already in Canberra preparing for the upcoming season.
The Cavs have been in constant contact with Burgamy since he returned to the USA, with negotiations ramping up about six weeks ago.
Cavalry general manager Thom Carter said Burgamy's return also helped build continuity for the fledgling club, instead of just having minor league players fly-in from the USA for one season.
"Brian Burgamy is a huge boost to anybody's offence," he told The Canberra Times. "The guy set records here last year for batting average and led the league in just about every offensive category and is a clutch hitter.
"He's just going to increase our [offensive] output, along with other players we've signed and brought across.
"We think we're going to have one heck of an offence this year."
Burgamy and Hightower aren't the only Cavalry players returning from last season.
Canberra products Hayden Beard, Steven Kent, Kyle Perkins and Ben Warner are also on the roster, while pitcher Brian Grening will be the No.1 starting pitcher.
