Foaled in Kentucky, the dark bay colt was owned and bred by Ogden Phipps. A son of the very important Champion sire, Bold Ruler, Reviewer finished his racing career with a record of 13: 9-3-1, and he won $247,223. He won the Sapling Stakes, Saratoga Special Stakes, Bay Shore Stakes, Swift Stakes, Nassua County Stakes, Roseben Handicap, and three others.
Ruffian was one of his first crop. The filly was euthanized in 1975 when she broke a leg. This possibly ran in the family, because in a paddock accident at Claiborne Farm, Reviewer broke his leg and had to be euthanized. Shenanigans, also, Ruffian's mother, was euthanized on May 21, 1977 when she broke two legs after waking from an intestinal surgery. Though not famous, Reviewer will always be remembered as the sire of the great Ruffian.
