Army Mule (horse)

Army Mule made his track debut in a maiden race over six and a half furlongs at Belmont Park on April 30, 2017 and started 1.55/1 joint-favourite in an eight-runner field. Ridden by John R. Velazquez he took the lead a quarter mile from the finish and drew away to win by eight and a half lengths from Zap Zap Zap in a time of 1:16.79.[6] A knee injury kept the colt off the track for the rest of the year.[7]

After an absence of nine months Army Mule returned to the track on January 31, 2018 when he was partnered by Javier Castellano in a six furlong allowance race at Gulfstream Park. Starting the 1/5 favourite he started slowly but went to the front a furlong out and won "impressively" by seven and a half lengths.[8]

On April 9 Army Mule was moved up sharply in class to contest the Grade I Carter Handicap over seven furlongs at Aqueduct Racetrack. Ridden by Joe Bravo, he was made the 2.1/1 second choice in the betting behind the five-year-old Awesome Slew (winner of the Commonwealth Stakes) in an eleven-runner field which also included Skyler's Scramjet (Tom Fool Handicap), Favorable Outcome (Swale Stakes) and Great Stuff (Toboggan Stakes). After racing in fourth place Army Mule moved up on the inside on the final turn and took the lead entering the straight. He quickly broke away from his opponents and came home six and a quarter lengths clear of Awesome Slew.[9] Pletcher commented "The sky's the limit with him. He's a super-talented horse. It's a matter of keeping him healthy" while Awesome Slew's jockey John Velasquez described the winner as "a monster".[7] Army Mule never raced again and was retired at the end of the season.

In the 2018 World's Best Racehorse Rankings Army Mule was given a rating of 119, making him the 59th best racehorse in the world and the third-best sprinter trained in the United States.[10]
