Ronnie O'Sullivan recovered from his heavy defeat at the Preston Grand Prix to thrash Stephen Maguire 6-0 in the Betfred Premier League.
O'Sullivan said he was "bored" with snooker last week
The world number one lost 9-2 to John Higgins on Sunday but made breaks of 83, 76, 74 and 131 in Derby.
"It was one of those nights," he said. "It happened to me last week. It's a silly game really, some days you feel great and others you don't.
"It's like a tap - it comes and goes - and tonight it was there."
