ELMONT, N.Y. &ndash; A year ago, trainer Tony Dutrow trained a New York-bred filly who used her brilliant speed to become a Grade 1 winner in the Ballerina. This year, Dutrow trains a Pennsylvania-bred filly who will try to use a similar running style to win Monday&rsquo;s Grade 1 Prioress at Belmont Park.\r\nQuantum Miss will get a chance to be considered in the same light as last year&rsquo;s Ballerina winner, Rightly So, when she seeks her fourth consecutive victory against five other 3-year-old fillies in the $250,000 Prioress, the featured event on a 10-race Fourth of July program. First post is 1 p.m.\r\nQuantum Miss, a Pennsylvania-bred daughter of Smoke Glacken, has won 5 of 7 starts, including the Grade 3 Cicada at Aqueduct. But the Prioress is certainly shaping up as her sternest test to date.\r\n&ldquo;Quantum Miss has got a lot to prove,&rdquo; said Dutrow, who won the 2009 Prioress with Cat Moves. &ldquo;Everyone can see that she&rsquo;s fast &ndash; there&rsquo;s no question about her being a fast horse &ndash; but I would think if you ran very good in the Prioress you would have to be among the best of your generation. Quantum Miss has that to prove. She&rsquo;s doing great, but she has to prove that.&rdquo;\r\nQuantum Miss is coming off a 12-length victory against Pennsylvania-breds in the Wonders Delight Stakes at Penn National on May 27. She ran six furlongs in 1:08.63 and earned a 104 Beyer Speed Figure.\r\nDutrow said if he knew Quantum Miss would have run that well, he would have trained her up to the Prioress. He added, &ldquo;If she runs the way she ran at Penn National that will be a sad day for the rest of them.&rdquo;\r\nQuantum Miss, who breaks from post 4 under Jeremy Rose, will have to outsprint several fleet-footed fillies, including California invader Alienation, the New Jersey shipper Our Year, and the locally based Roman Treasure.\r\nAlienation, second in last year&rsquo;s Grade 1 Spinaway at Saratoga, made an impressive 3-year-old debut winning a first-level allowance race by 7 3/4 lengths at Hollywood Park in her first start since having a chip taken out of ankle.\r\n&ldquo;The whole thing is pace,&rdquo; trainer Bob Baffert said. &ldquo;She just goes as fast as she can go for as long as she can; there&rsquo;s no rating for her.&rdquo;\r\nRoman Treasure has won two straight races on the front end after finishing fourth to Quantum Miss. She has displayed considerable speed in her last two races.\r\nIf there is a pace meltdown, Pomeroys Pistol could be the biggest beneficiary. An upset winner of the Grade 2 Forward Gal earlier in the year, Pomeroys Pistol comes off a win in the Just Smashing Stakes at Monmouth Park on June 11. Cornelio Velasquez rides from post 6.\r\nHer Smile also figures to be running late under Javier Castellano.
