In between, the Cats set professional sports records that have never been equaled, including winning the Texas League title six years in a row and establishing themselves as perhaps the most famous minor league team in baseball history. From vintage Panthers such as power-hitting first baseman Clarence "Big Boy" Kraft and colorful Hall-of-Fame manager Rogers Hornsby to more modern Cats heroes such as Duke Snider, Carl Erskine, and Maury Wills, Fort Worth and the baseball-obsessed Southwest formed a high profile partnership that even survived a season when the spectator stands burned one day and the playing field was flooded a week later. Cats fans wouldn't be denied; they sat around the field on folding chairs, and no games were postponed.

Partially oral history, When Panthers Roared includes interviews with baseball greats Hank Aaron, Wally Moon, Dick Williams, Maury Wills, and co-author Bobby Bragan. Williams and Wills were Cats mainstays; Bragan managed the team during its great post-WW II years when baseball guru Branch Rickey made Fort Worth part of the Brooklyn Dodger farm system and stocked it with his finest young athletes.

But during the Cats heyday, there were just sixteen major league teams who played out of ten U.S. cities. When Panthers Roared captures the excitement and pride the minor-league Cats brought to Texas and the Southwest. It was a time when, Bobby Bragan insists, "any man lucky enough to be a Fort Worth Cat was as proud of that as he would have been to play for the New York Yankees."

When Panthers Roared is lavishly illustrated through the cooperation of Mark Presswood, whose sports collection features Cats memorabilia. Additional short interviews feature the late Joe DiMaggio, Vincent Devaney, and Leo Durocher.
