The Athletics' Triple-A club, the Sacramento River Cats, has submitted plans to part ways with Oakland.
Sources from both teams first mentioned ending ties in May, with River Cats management broaching the possibility of becoming a San Francisco Giants affiliate. Since moving to Sacramento in 2000, the River Cats have topped the minor leagues in attendance eight times and brought home seven Pacific Coast League titles.
The River Cats' departure from Oakland's system would be a loss for the A's, said Slusser, due to both the club's proximity to Oakland and its desirability as a destination for minor league players. The Giants' affiliation with Triple-A Fresno also ends after this season.
