2018: two-year-old season Game Winner earned a "Rising Star" designation from the
Thoroughbred Daily News for his performance in his first start on August 18, 2018, at
Del Mar, a six-furlong
maiden special weight race. Drawing the outside post position in a field of nine, he was carried wide around the turn while contesting the early pace. He assumed the lead around as they entered the stretch and continued to draw away, winning by lengths. Game Winner made his next start in the
American Pharoah Stakes on September 29, going off as the 3-10 favorite in a field of five. He pressed the early pace set by Rowayton, then moved to the lead around the far turn and pulled away in the final furlong for a lengths. It was Baffert's eighth win in the race formerly known as the FrontRunner Stakes and renamed for Baffert's Triple Crown winner
American Pharoah. "[Game Winner] tipped us off this summer that he was going to be a good one. He is strong and he still looks a little heavy," said Baffert. "I don't plan to do too much with him before the Breeders' Cup. The good ones get there. I was very happy to win the first American Pharoah. Pretty cool and nice of Santa Anita to name a race after him. We had the same groom on this horse as American Pharoah [Eduardo Luna]." The win established Game Winner as an early favorite for the
2019 Kentucky Derby. Sportswriter
Steve Haskin cited the colt's flexible running style (having won from both on and off the pace), his superior breeding, and Baffert's recent successes with
Arrogate and
Justify in addition to American Pharoah. Fourteen horses were entered in the
Breeders' Cup Juvenile on November 2, held in 2018 at
Churchill Downs. However, the highly regarded Code of Honor was scratched after developing a fever, leaving thirteen to go to post with Game Winner as the even-money favorite. Game Winner was bumped at the start, then settled in mid-pack while being carried wide around the first turn. He continued to race wide down the backstretch, then started his move on the final turn. Meanwhile, longshot Knicks Go pressed the early pace and moved to the lead at the head of the stretch. Game Winner gradually made up ground despite bumping with Knicks Go in midstretch and pulled away late to win by lengths. "He broke fine, but it looked like they took my spot, and I had to go wide," said jockey
Joel Rosario. "He seemed like he didn't mind that. He was comfortable. That's why we got him moving at that point, instead of getting inside and taking back. Turning for home, the more I rode him, the more he gave it to me."
2019: three-year-old campaign Game Winner was supposed to make his three-year-old debut in the
San Felipe Stakes on March 9, 2019, but that race was cancelled due to the temporary closure of Santa Anita. Instead, he was shipped to
Oaklawn Park for the
Rebel Stakes a week later. Due to the large number of entries, the Rebel was split into two races, with Game Winner going off as the favorite in the second division. At the break, he bumped with Jersey Agenda to his inside and fell back to sixth place. Down the backstretch, he remained in sixth and was just over three lengths behind the pacesetter, Omaha Beach. Around the final turn, Game Winner commenced his drive and moved into second while racing four wide. Omaha Beach re-opened a two-length advantage in mid-stretch, but Game Winner started closing again. Omaha Beach fought back and won by a nose despite being bumped by Game Winner near the wire. On April 6, shortly after Santa Anita was re-opened for racing, Game Winner entered the
Santa Anita Derby. He went off as the favorite in a field of six, with the second choice being stablemate Roadster. Game Winner raced four-wide around the first turn and backstretch, then started his move on the far turn while racing three wide. He briefly moved to the lead in mid-stretch but could not match the closing kick of Roadster, who had saved ground along the rail throughout the race. Game Winner finished second, beaten by half a length. Game Winner did not enter the
2019 Preakness Stakes, and in late May, Baffert ruled him out of running in the
2019 Belmont Stakes. It was later revealed that the colt was suffering from a bad back, from which he was given some time off to recover. He returned to the racecourse on July 13 in the
Los Alamitos Derby, winning by five lengths as the 1-20 favorite. ==Statistics==
