One month into the regular season, she was traded to the Duluth–Superior Dukes.
She pitched from the bullpen for both teams, seeing limited use.
Her 1997 season totals were a 7.53 ERA, 15 appearances, 14 innings, allowing 24 hits and 9 walks while striking out 11. She returned to the Dukes for the 1998 season, pitching from the bullpen at first, but then on Thursday, July 7, 1998, she was made a starting pitcher, making her the first woman pitcher to start a men's professional baseball game.
The game was an 8-3 home loss to the Sioux Falls Canaries.
Returning to the Dukes in 1999, a new manager returned Borders to bullpen duty.
