Mark Allen played brutal hardball as he swatted aside Belgian teenager Luca Brecel at the Coral UK Championship.
The 28-year-old Northern Irishman, runner-up at the York-staged tournament three years ago, beat Brecel 6-0 at the Barbican Centre to clinch a place in the third round.
World number 40 Doherty found himself 3-0 down early on against 26-ranked Welshman White but rattled off four frames in succession, including a break of 109 in the sixth, to take the lead.
White stopped the rot to make it 4-4 but Doherty took the final two frames with ease to book his place in the third round.
Doherty will face world number eight Ricky Walden in Monday morning's third round. Walden edged out Robbie Williams 6-5.
Allen must get past Rod Lawlor, who at 35 is ranked 29 places below the Antrim native.
Allen has been a beaten finalist in the Shanghai Masters and International Championship already this season and has his sights on a major prize, which is why he did not want to give 19-year-old Brecel the slightest chance of an upset.
"I had a game plan to not take on any silly shots against Luca," Allen told a press conference.
"He's not the sort of player you want to let build up confidence.
"He's a very streaky player and I knew if he got a few frames on the board he'd be hard to stop."
Allen refused a number of pots he admitted he might have taken on against other opponents, preferring to put Brecel in trouble.
"I turned down a couple of tricky ones early doors, I didn't miss many when I was in the balls, and I made it hard for him really," Allen added.
"I didn't really want to give him any sniff into the match easily, I wanted to make him work for it and I feel I stuck to my game plan well today."
Reigning champion Neil Robertson paid a poignant tribute to fellow Australian Phillip Hughes before battling back from the brink of defeat.
The 32-year-old, a big cricket fan who enjoyed making an unprecedented century of centuries on the baize last season, brought out a bat along with his cue for the York Barbican Centre second-round clash with Kyren Wilson.
Melbourne-born Robertson was joining in the appreciation of Hughes which has come from around the world of sport since the batsman's death on Thursday.
The bat stayed out in the arena with Robertson, who at one stage looked to be heading out of the tournament but scraped a 6-5 win.
Robertson fell 5-4 behind when Wilson made 87 in the ninth frame, and when the 22-year-old English potter fluked the final red in the next he had a clear match-winning opportunity.
Yet Wilson fluffed a crucial positional shot from green to brown, and a relieved Robertson was able to pot brown and blue to force the decider.
Wilson had the first chance of the all-important 11th frame, but missed a tricky red and left a half-decent chance. Robertson showed why offering him any such opening is a mistake by rattling in an 86 break to secure a pass to the third round.
Meanwhile, Ronnie O'Sullivan confirmed he would be in evening action against Leeds potter Peter Lines.
The four-time UK champion has a broken ankle and suggested after a first-round win over Daniel Wells that he may have to withdraw from the tournament, but O'Sullivan wrote on Twitter he was "gonna give the ankle a go" against 44-year-old Lines.
Other winners on Sunday afternoon included Peter Ebdon and Stephen Maguire.
