Amerman Racing LLC’s Blue Heart saved all the ground before launching a decisive run to capture the $250,000 Bison City Stakes, Sunday at Woodbine.

The 1 1/16 mile-event is the second jewel of the Triple Tiara, for three-year-old fillies, foaled in Canada.

The Exchange Rate-Flawless Diamond filly, trained by Brian Lynch and ridden by Alex Solis, waited in third position along the rail as Casa Loma led the field through moderate splits of :25.45, :49.88 and 1:14.18.  Casa Loma maintained a one-length advantage at the top of the lane, but with a sixteenth of a mile to run, Solis angled Blue Heart off the rail to score a comfortable length and three-quarter win. A rallying Black Bird Rock nosed out Casa Loma for place. The final running time was 1:45.77.

Solis, who captured the first leg of the Triple Tiara with Irish Mission in the Woodbine Oaks, was impressed with his filly’s turn of foot through the stretch.

“I waited down on the inside,” said Solis. “When I asked her to go at the three-sixteenths (pole), she responded nicely. I felt like she had an easy race. She saved all the ground, and only ran 300 yards.”

Blue Heart, who entered the Bison City off a narrow neck loss in the Alywow Stakes, improved her record to three wins, a second and a third in six lifetime starts.

The third jewel of the Triple Tiara series is the Wonder Where Stakes, slated for July 29.

Blue Heart returned $6.20, $3 and $2.40, pairing with Black Bird Rock ($2.90, $2.20) for a $16.60 (3-6) exactor.  A 3-6-4 (Casa Loma, $2.90 to show) triactor was worth $61.90. Northern Passion was scratched.
