Belfast Giants spoiled Cardiff Devils' 1,000th Elite League game on Sunday, handing the defending champions a heavy defeat at Ice Arena Wales.
The top-of-the-table visitors won thanks to four Kyle Baun goals, Jim Vandermeer's brace plus strikes from Blair Riley and Darcy Murphy.
Sean Bentivoglio's second-period goal was Devils' sole return.
Devils had at least ended a three-game losing streak the previous night, winning 4-2 at Milton Keynes Lightning.
The Welsh side was coming off defeats to Fife Flyers, Nottingham Panthers and Coventry Blaze.
Giants had won 4-0 at Panthers on Saturday to keep their 2018-19 title bid on course.
