Mikki Queen

On 7 December 2014 Mikki Queen began her racing career by finishing a close second to Gilda in an event for hitherto unraced juveniles over 1400 metres at Hanshin Racecourse. Two weeks later at the same track the filly recorded her first success as she won from seventeen opponents in a maiden race over 1600 metres.[6]

Mikki Queen began her second campaign in the Daily Hai Queen Cup (a trial race for the Oka Sho) over 1600 metres at Tokyo Racecourse in February and finished second to Cat Coin, beaten a neck by the winner. The filly missed the Oka Sho in April, as she had not earned sufficient prize money, and was stepped up in trip to win Wasurenagusa Sho over 2000 metres earlier on the card.[6]

In the 76th running of the Yushun Himba over 2400 metres at Tokyo on 24 May Mikki Queen started the 5.8/1 third favourite behind Rouge Buck (winner of the Kisaragi Sho) and the Oka Sho winner Let's Go Donki. The other fourteen runners included Kokorono Ai (Tulip Sho), Queens Ring (Fillies' Revue), Culminar (2nd in the Oka Sho) and Cat Coin. After racing towards the rear of the field, Mikki Queen produced a strong run in the straight, gained the advantage 50 metres from the finish and won by three-quarters of a length from Rouge Buck. Hamanaka commented "I'm so happy she was able to demonstrate her ability. I especially concentrated on her break since she's been struggling at it so far. I thought I would relax her so to get her turn of foot at the stretch. She responded well and quickened being driven, so I just prayed for the best."[7]

After a break of almost four months Mikki Queen returned for the Rose Stakes (a trial for the Shuka Sho) over 1800 metres at Hanshin. She came from last place on the final turn to finish second one and half lengths behind the winner Touching Speech with third place going to Tosen Victory. On 18 October the filly started 2/1 favourite for the 20th edition of the Shuka Sho over 2000 metres at Kyoto Racecourse when her seventeen opponents included Touching Speech, Let's Go Donki, Tosen Victory, Queens Ring, Kokorono Ai and Cat Coin. Starting from a draw on the far outside she raced in eighth place before making rapid progress on the inside in the straight and after taking the lead 100 metres out she held off the late challenge of Queens Ring to win by a neck. The winning time of 1:56.9 was a new record for the race. After the race Hamanaka said "she was just amazing. Her usual slow start wasn't that bad today and since the pace and surface was fast, I intentionally kept her near the pace. At the top of the stretch, I asked her to go right through the group of horses instead of going wide because I had faith in her strength and she responded beautifully."[8]

On her final race of the year Mikki Queen was matched against older horses and started third favourite for the Japan Cup over 2400 metres at Tokyo on 29 November. She came home eighth of eighteen runners, two and a half lengths behind the winner Shonan Pandora.[9]

In the JRA Awards for 2015 Mikki Queen topped the poll for the JRA Award for Best Three-Year-Old Filly taking all 291 of the votes.[10] In the official Japanese rankings Mikki Queen was rated equal with Let's Go Donki as the best three-year-old filly, nine pounds behind the top colt Duramente.[11]

On her four-year-old debut Mikki Queen started favourite for the Grade 2 Hanshin Himba Stakes over 1600 metres in April but failed by a neck to catch the front-running six-year-old mare Smart Layer. In the Grade 1 Victoria Mile at Tokyo in the following month she again started favourite but despite making rapid progress from the rear of the field in the straight she was beaten two and a half lengths into second by Straight Girl with Shonan Pandora and Smart Layer in third and fourth.[12] Mikki Queen's return in autumn was delayed by an injury to her left foreleg[13] and she was off the track for almost six months before contesting the Queen Elizabeth II Cup at Kyoto in November when she finished well to take third behind Queens Ring and Sing With Joy. On 25 December she ended her campaign by running fifth to Satono Diamond in the Arima Kinen.

In the JRA Awards for 2016 Mikki Queen finished fourth behind Marialite, Queens Ring and Straight Girl in the voting for the JRA Award for Best Older Filly or Mare.[14] She was rated the third best older filly or mare in Japan behind Marialite and Straight Girl in the official Japanese ratings.[15]

Mikki Queen began her fourth campaign on 8 April with a second attempt to win the Hanshin Himba Stakes and started 1.2/1 favourite ahead of fifteen opponents including Queens Ring, Admire Lead (Victoria Mile), Jour Polaire, Denim and Ruby (runner-up in the Japan Cup), Touching Speech and Meisho Mambo. After being settled in eighth place by Hamanaka, Mikki Queen was switched to the outside in the straight and took the lead in the closing stages to win by one and three quarter lengths from Admire Lead.[16] She started odds-on favourite for the Victoria Mile on 14 May but after having trouble obtaining a clear run in the straight she came home seventh behind Admire Lead. On 25 June the mare was moved back up in distance to take on male opposition in the Takarazuka Kinen over 2200 metres at Hanshin and produced one of her best efforts as he finished third behind Satono Crown and Gold Actor with Rainbow Line, Cheval Grand and Kitasan Black finishing further back. As in the previous year, Mikki Queen began her autumn campaign by running third in the Queen Elizabeth II Cup; on this occasion she produced a "powerful late run" but was beaten a neck and a head by Mozu Katchan and Crocosmia in a three-way photo finish.[17] The mare ended her track career on 24 December when she came home unplaced behind Kitasan Black in the Arima Kinen.

In the JRA Awards for 2017 Mikki Queen finished third behind Vivlos and Admire Lead in the voting for the JRA Award for Best Older Filly or Mare.[18] She was rated the third best older filly or mare in Japan behind Vivlos and Queens Ring in the official Japanese ratings.[19]
