OZONE PARK, N.Y. &ndash; Uncle T Seven and Mother Russia, respective winners of the New York Stallion&rsquo;s Thunder Rumble and Staten Island divisions last year, defend their titles in those $75,000, seven-furlong races Sunday at Aqueduct.\r\nBoth break from the rail in short fields. Mother Russia, a five-time stakes winner for Linda Rice, takes on five rivals, including stablemates Healthy Debate and We Need V L T&rsquo;s.\r\nAfter running in a trio of Grade 3 stakes on turf and synthetic tracks, Mother Russia made her first dirt start of the year in the Iroquois, and was disqualified from fourth after coming out and impeding a rival on the turn. Mother Russia gets a switch back to Ramon Dominguez, who was 5 for 6 on the filly last year.\r\nUncle T Seven turns back an effort on turf in the Mohawk Stakes, just as he did last year. In addition to last year&rsquo;s Thunder Rumble, Uncle T Seven has won New York Stallion races on Aqueduct&rsquo;s inner dirt and on turf at Saratoga, and won the Ashley T. Cole on Belmont&rsquo;s inner turf two starts back.\r\n&ldquo;He&rsquo;s a nice, versatile horse,&rdquo; said trainer John Kimmel.\r\nTo repeat, Uncle T Seven must get past General Maximus, a 3-year-old coming off a career-best effort to win the Hudson in 1:08.84, the second-fastest time in that race since it was shortened to six furlongs in 1994.\r\n&ldquo;He came out of that race in wonderful shape,&rdquo; said trainer John Terranova. &ldquo;I think he&rsquo;s got a shot to be a top sprinter next year, so we&rsquo;ll see what happens.&rdquo;\r\nDriven by Success threw his head at the start and wound up fourth in defense of his Hudson title; he drew favorably toward the outside for Todd Pletcher.\r\nThe Fifth Avenue and Great White Way divisions for 2-year-olds failed to fill, and will be run back combined as the Great White Way on Wednesday.\r\n◗ Among four turf races is race 6, the $60,000 Memories of Silver overnight stakes for 3-year-old fillies at a mile.\r\nJimmy Toner, who developed Memories of Silver into a multiple graded winner, switches Much Rejoicing to the grass; Toner also trained Much Rejoicing&rsquo;s dam, Soaring Softly, the champion turf mare of 1999.\r\nIsland Time, Sea Road, and Ultimate Class are contenders.\r\n◗ Zenyatta&rsquo;s 3-year-old half-brother, Souper Spectacular, seeks his third straight turf win for Seth Benzel in the opener.
