The 13-1 long shot was one of five fresh horses in the Preakness that didn't run two weeks ago in the Kentucky Derby.
Derby winner Always Dreaming and Classic Empire dueled throughout most of the race before Classic Empire stuck his nose in front midway on the far turn. It looked as if Classic Empire would go on to win, but Cloud Computing ran him down on the outside.
Ridden by Javier Castellano, Cloud Computing ran 1 3/16 miles in 1:55.98 and paid $28.80 to win. It was just the dark brown colt's second career victory.
Senior Investment, a 30-1 shot, finished third. Lookin At Lee was fourth.
