The Yorkshire player, who last played for England in the sixth and final Test against the West Indies at Trent Bridge in August last year, re-established his credentials for the Test all-rounder's place with an unbeaten 92 as the tourists reached 231 for 4 at the close.
White's vital contribution, which included crucial partnerships with Mark Butcher and Adam Hollioake, enabled England to recover from losing Michael Vaughan, Anthony McGrath and Owais Shah, which had left them struggling on 59 for 3.
White, dropped twice on 45 and 85, overcame numerous weather interruptions to steer the tourists out of trouble with a 78-run stand with Butcher, who fell for 55 after being brilliantly stumped by the wicketkeeper Peter Roach off the off-spinner Brad Hodge.
White continued his assault and hammered 11 fours in an innings lasting more than three hours to finish just eight short of England A's first century of the tour, having combined with Hollioake (45no) in an unbroken 94-run fifth-wicket partnership.
