INGLEWOOD, Calif. - When Star Billing was about two lengths in front in the final furlong of Saturday&rsquo;s $100,000 Senorita Stakes at Hollywood Park, jockey Chantal Sutherland was already shouting.\r\nIt was not all in celebration of an imminent second stakes win of the day for Sutherland.\r\n&ldquo;She was looking around,&rdquo; Sutherland said of Star Billing. &ldquo;Her ears went forward. I started screaming&rdquo;\r\nA little vocal encouragement seemed to help Star Billing in the final strides as she held her advantage to win by 2 3/4 lengths over 42-1 Entrustment. Cambina, the 4-5 favorite, finished third in the field of seven 3-year-old fillies, closing from last.\r\nSutherland, who won the Cool Frenchy Stakes earlier on M One Rifle, had Star Billing well-placed throughout, stalking Wave of Applause, who set early fractions of 23.41 and 47.09 seconds. Star Billing reached the front in early stretch, and ran a mile on turf in the Grade 3 Senorita in 1:34.52. She paid $19.20.\r\nSutherland said that Star Billing is focused with a target in front of her. &ldquo;She does like to aim at a horse,&rdquo; she said. &ldquo;She can sit and wait.&rdquo;\r\nStar Billing races for breeder George Krikorian and trainer John Shirreffs, and is unbeaten in two starts. Star Billing won a maiden race on the hillside turf course at Santa Anita in March in her debut. By Dynaformer, Star Billing has earned $92,400.\r\nCool Frenchy: M One Rifle sets track record\r\nM One Rifle set a five-furlong track record of 55.98 seconds with a half-length win over previous record holder Cost of Freedom in Saturday&rsquo;s $91,010 Cool Frenchy Stakes.\r\nM One Rifle ($9.60) stalked Cost of Freedom, who set early fractions of 22.14 and 44.28 seconds for the first half-mile. Sutherland guided M One Rifle between horses in early stretch and took the lead in the final sixteenth.\r\n&ldquo;He kicked in so hard on the turn, I fell back in the saddle a touch,&rdquo; Sutherland said. &ldquo;It was like, wow, what a great acceleration.&rdquo;\r\nCost of Freedom, who held the previous five-furlong mark of 56.14 seconds set last December, held second, finishing 2 1/2 lengths in front of Bulldogger in the field of six.\r\nThe Cool Frenchy Stakes was M One Rifle&rsquo;s first stakes win since the Grade 1 Malibu Stakes at Santa Anita in December. Owned by a partnership, M One Rifle, a 5-year-old gelding, has won 5 of 13 starts and $470,002.
