Several times during 1924 Mother Goose would go head-to-head with her very good stablemate Maud Muller, a filly who was also bred and owned by Harry Whitney. Trained by Fred Hopkins, the two fillies would share American Co-Champion Two-Year-Old Filly honors. Mother Goose got her first career win on April 24, 1924 in a four and a half furlong event for two-year-old maiden fillies at Havre de Grace Racetrack. Ridden by Linus McAtee she won by two lengths, easily defeating six other runners while breaking the track record by two-fifths of a second. At Jamaica Race Course, Mother Goose ran third in the May 13 Rosedale Stakes under future Hall of Fame jockey Ivan Parke. A rarity in racing, the winner Maud Miller, runner-up Swinging, and third place finisher Mother Goose all had the same owner and trainer. On May 25, Mother Goose earned first place money of $4,925 for winning the five furlong Fashion Stakes at Belmont Park under jockey Jimmy Burke beating stablemate Maud Muller by 1½ lengths in a field of seven. At Aqueduct Racetrack Mother Goose ran second to stablemate Maud Muller in the July 4 Astoria Stakes run at five furlongs. For the huge field of twenty-nine juveniles competing in the September 14 Belmont Futurity Stakes it would be the most important event of their year and a race with a winner's share 13 times what Mother Goose had earned for her win in the Fashion Stakes. Run at a distance of 6 furlongs, jockey Linus McAtee positioned the filly well and as they came into the homestretch Mother Goose was running second to J. Edwin Griffith's good colt Single Foot, a very good colt who had already won several top stakes on Maryland racetracks. Taking the lead, Mother Goose held off a strong charge from Marshall Field'sPimlico Futurity winner Stimulus to take the $65,730 first place money by a head. From ten starts in 1924, Mother Goose ended her two-year-old campaign with a record of 3-1-3. She had earnings of $72,755 which ranked second in the United States to Master Charlie.
1925: Three-year-old season
On April 16 the Daily Racing Form reported that Mother Goose was being trained in Maryland for participation in the 1925 Kentucky Derby to be run May 16. She was also nominated for the May 30Kentucky Oaks, and for the Preakness Stakes which in 1925 would be run eight days prior to the Kentucky Derby. Mother Goose did not run in any of these events and would end her career without racing as a three-year-old.
Broodmare legacy
Mother Goose was sent to Whitney Farm near Lexington, Kentucky to stand as a broodmare. While none of her progeny made an impact in racing, her daughter Arbitrator by Peace Chance was the dam of Almahmoud who was bred by Harry Whitney's son, Cornelius Vanderbilt Whitney. Almahmoud holds an important place in Thoroughbred breeding as the dam of both Cosmah and Natalma. Cosmah was a top quality broodmare whose progeny includes Halo. Natalma was the dam of legendary sire and sire of sires Northern Dancer.
