Since the creation of the Scottish Premier Division in 1975 and the introduction of four league games between clubs in a Scottish season, neither club has managed to win all four league derbies in a season. Hearts have achieved three wins and a draw five times, in 1985–86, 1989–90, 1990–91, 1996–97 and 2006–07. Hibs' best record in a league season is also three wins and a draw, in 1975–76. Hearts whitewashed Hibs in the 2011–12 season, winning all three league games and the Scottish Cup Final; however, a fourth league fixture was not possible as the clubs were not in the same section of the league after the split.
