Gray sends 'Whirlwind' spinning out
White's 10-5 defeat means he has suffered the same fate as John Parrott, another Crucible hero, in sliding down the rankings to a point where he will need to win two qualifying matches to secure a return to Sheffield next year.
It rounded off a terrible season for the six-times former World Championship runner-up, who began the campaign ranked number eight.
Playing his practice partner, the 43-year-old Londoner was always behind from the moment Gray knocked in a break of 65 to capture the opening frame.
He trailed 6-3 overnight and while the crowd hoped for a memorable comeback yesterday, they were quickly disappointed as Gray took the first three frames, two of which he pinched on the black.
White stopped the rot by making it 9-5 but a missed long brown finally killed off his chances as Gray moved through to a second-round meeting with Peter Ebdon.
"I never got going and really struggled - it was very frustrating," said White, who was appearing at the Crucible for the 25th year.
"I've been playing really well in practice but you need to do it under pressure and I just can't seem to take my form to the match table. I need to find a way to do that.
"I still love this game and still think I'm good enough to compete. I'll carry on until I know I can't play anymore. I'll go to Prestatyn for the qualifiers, give it my all and hopefully get back in next year."
Following news that the much-criticised tables in the arena are to be re-clothed at the weekend, White described the one on which he played as "abysmal" but stressed it had not affected the result.
"It's not the table fitter's fault but there were a tremendous amount of kicks," he added. "I couldn't play a safety shot on it. But it's no excuse for the balls I missed - I missed some gimmes."
Gray has been a long-time friend of White's and felt sympathy for the plight of the game's most popular player.
"It's not nice but that's snooker," said the world number 22. "There are no friends when you're at the table.
"But I feel for Jimmy. He's too good a player to be in the situation he is but he put himself under a lot of pressure with his results this season."
The second round got underway with Australia's Neil Robertson taking a 6-2 lead against Stephen Lee in a high-quality opening session.
After a scrappy first two frames, it became vital to get among the balls first as Robertson knocked in breaks of 109, 74 and 73, and Lee responded with a 135 and a 64.
Ronnie O'Sullivan's second-round opponent was confirmed when Ryan Day ousted 15th seed Joe Perry with a crushing 10-3 success.
After making a break of 97 in the opening frame it was all downhill for Perry, who was 7-2 behind going into last night's conclusion and could find no way back into the match.
Day, edged out on the final pink by John Higgins on his only other Crucible appearance in 2004, looked composed and clinched the win with a fine 41 clearance, sinking a tricky black with the rest.
"I kept Joe under pressure and did what I had to," said the 26-year-old Welshman.
"Joe didn't play as well as he can, but I felt I had more to give and was really focused on getting the match finished."
On his clash with O'Sullivan, the world number 32 added: "If you had a choice of opponent you wouldn't go for Ronnie but that's the way the draw is. I'll have to make a good start and see how it goes from there."
Perry said: "I don't know if you can practice too hard but I left all my form on the practice table. I made a lot of unforced errors and you can't afford to miss pots against anyone.
"Ryan got more confident as I missed and ran away with it. It was all my own doing."
