There were some pretty fast 2-year-olds at Canterbury Park this summer, and the two fastest hooked up Saturday in an exciting edition of the $80,000 Shakopee Juvenile on closing day of the 2017 meeting. Headed in midstretch by Mr. Jagermeister, the filly Amy’s Challenge battled back and won by three-quarters of a length. “You’re always proud when one gets headed and comes back to win, whether it’s a $2,500 claimer or a stakes horse,” winning trainer Mac Robertson said. Off taxing splits of 21.95, 44.48, and 56.67, Amy’s Challenge ran six furlongs in a swift 1:09.58. Her time was .44 seconds faster than that of the older horse Sir Navigator, who won the $50,000 Tom Metzen H.B.P.A Sprint Stakes one race earlier. Mr. Jagermeister, who is light years better than the average Minnesota-bred, finished 18 lengths in front of third-place My Sweet Emma. Mr. Jagermeister has twice walloped Minnesota-breds and finished second in the Prairie Gold Juvenile to The Tabulator, who won the Iroquois Stakes on Saturday at Churchill Downs. Amy’s Challenge debuted Aug. 6 at Canterbury and won a 5 1/2–furlong maiden race by 16 1/2 lengths, but Mr. Jagermeister gave her a real test Saturday. Amy’s Challenge and jockey Jareth Loveberry broke on top and opened a clear early lead as Mr. Jagermeister, who has learned his lessons well the last two months, rated a few lengths off the lead while racing wide into the far turn. Moving up smoothly, Mr. Jagermeister closed on Amy’s Challenge past the three-furlong pole and to the quarter pole, reached her flank after straightening for home, and for a half-furlong or so appeared to be doing the better work. But Amy’s Challenge rose to the challenge, getting back on terms and edging clear in deep stretch. “I heard the horse on the outside, and I was pretty sure it was Jagermeister,” Loveberry said. “He got a head on me, but she dug in. She could be the real deal. She’s very settled all the time. She just glides. She’s fast - very fast.” Amy’s Challenge paid $3.60 to win. By Artie Schiller out of Jump Up, by Jump Start, she is owned by the Novogratz Racing Stable. “I thought she got a little tired, but I expected her to get tired,” Robertson said. “I didn’t train her real hard. At the sixteenth pole she kept going and galloped out real good. I didn’t think she’d have to run [1:09] and change to win it.” Amy’s Challenge has been aimed for weeks at the Oct. 6 Alcibiades Stakes at Keeneland, and Robertson said that race remains her goal. The filly will stay at Canterbury for a week or 10 days, ship to Chicago and spend one night in the shed row of Robertson’s father Hugh, then go on to Keeneland, where she’ll have a timed workout to determine her final status for the Alcibiades. ** Robertson also won the $50,000 Tom Metzen H.B.P.A Sprint Stakes with Sir Navigator, who was ridden to victory by Israel Hernandez for the Jer-Mar Stable. Sir Navigator ($11.20) battled throughout the six-furlong race with Smooth Chiraz, who eventually capitulated and finished second, beaten 1 1/2 lengths. Adens Dream was third, as Sir Navigator, a 5-year-old gelding by Henrythenavigator, stopped the timer in 1:10.02.
