In her three-year-old debut, Fiftyshadesofhay's connections tested her on the grass on New Year's Day in the $75,000 Blue Norther Stakes at Santa Anita Park at a mile. She broke eighth, moved up to fourth, and faded back to finish eighth in a field of eleven.[6]
Four weeks later, on January 26, 2013, Bob Baffert put Fiftyshadesofhay back on the dirt in the $100,000 Grade 3 Santa Ysabel Stakes at a mile and one sixteenth at Santa Anita. She broke second under jockey Rafael Bejarano by one and half lengths. Moving into the final turn, she overtook the leader and in the stretch pulled clear and won by five and three quarter lengths.[7]
Fiftyshadesofhay's connections decided to step up in class and race her against the best fillies in the western half of the country in the $250,000 Grade 1 Las Virgenes Stakes at Santa Anita Park at a mile on the dirt.[8] On March 2, 2013, she was sent off as the second favorite at 2–1 in a field of eight. Under jockey Rafael Bejarano, she broke second and maintained that position throughout the race just off the rail. Fiftyshadesofhay finished three and a half lengths behind eventual Kentucky Oaks runner-up Beholder. She beat third-place finisher Scarlet Strike by one and half lengths and the rest of the field by two to ten lengths.[8]
Next on the docket for Fiftyshadesofhay was the premier race on the West Coast for three-year old fillies: the $300,000 Grade 1 Santa Anita Oaks, run on April 6, 2013, as the week's featured race at a mile and one sixteenth. It featured a compact field of six. In that race, Fiftyshadesofhay broke a step slowly in fourth under Bejarano again.[9] She stalked the leaders and moved up to second on the backstretch. Beholder won by about three lengths. In deep stretch, Fiftyshadesofhay was nipped at the wire for second by a head by 16-1 longshot Iotapa.[9]
On May 17, 2013, trainer Bob Baffert and owners Mike Pegram, Karl Watson and Paul Weitman decided to ship Fiftyshadesofhay to Pimlico Race Course in Baltimore, Maryland, to run in the second jewel of de facto Filly Triple Crown, the $500,000 Grade 2 Black-Eyed Susan Stakes. Nine three year-old fillies were entered, with Grade 1 Ashland Stakes winner Emollient the odds-on favorite at 4–5. In that one mile and one eighth race on dirt, Fiftyshadesofhay broke second under new jockey Joel Rosario but was quickly subdued and settled into sixth place passing the stands for the first time under the wire.[10] At the clubhouse turn, she was almost five lengths back ahead of only Lady Banks. Down the backstretch, she edged up into fifth, still six lengths behind leader Maracuya under John Velazquez.[10]
Around the far turn, Fiftyshadesofhay moved up under hand urging by Rosario into contention in fourth place. She ducked in slightly toward the rail into the two path and then swept around the leaders into about the seven path down the lane.[10] Fiftyshadesofhay passed Toastng and pace setter Maracuya, challenging the leader, Marathon Lady. Just after the sixteenth pole, she collared Marathon Lady and surged near the wire to win the 89th running of the Black-Eyed Susan Stakes by a neck in a time of 1:52.73.[10]
Baffert was quoted at the end of May as saying, "She will definitely be back out on the road this summer with the Grade 1 Alabama Stakes at Saratoga Race Course being her next major objective."
On June 29, 2013, Fiftyshadesofhay won the mile and one sixteenth Iowa Oaks at Prairie Meadows Racetrack in Altoona, Iowa. She stalked the leader in second place for most of the race. Then, around the final turn, she took over the lead and won by four lengths over Seaneen Girl and So Many Ways.
Fiftyshadesofhay raced again on August 17, 2013, in the Grade 1 $600,000 Alabama Stakes at Saratoga Race Course. She finished second to heavy favorite Princess of Sylmar as the 7-2 second choice.
