After lucking out with weather during November and most of December, Fair Grounds has hit one of its drawn-out off-the-grass periods. Races were rained off turf four of five days last week, and grass racing was canceled again Friday. But rain or shine, turf or dirt, Sunday&rsquo;s first race should showcase a strong 3-year-old prospect.\r\nEntered main-track-only is twice-started Prime Cut, who is set to make his two-turn debut in an entry-level allowance carded at one mile on grass. In the main body of the field is Mavericking, a sharp maiden turf winner during this meet&rsquo;s opening week, and more recently a closing second on grass while facing winners for the first time. Sunday&rsquo;s first is scheduled for one mile, but would move to one mile 70 yards if taken off turf.\r\nIt remains to be determined whether Mavericking will start in the event of a surface switch, trainer Neil Pessin said. Mavericking, a Team Block homebred, made his first three starts on Polytrack before switching to grass at Fair Grounds.\r\n&ldquo;That&rsquo;s still under discussion,&rdquo; Pessin said of Mavericking&rsquo;s main-track participation. &ldquo;If it&rsquo;s sloppy it&rsquo;s going to be a question. If it&rsquo;s fast, he&rsquo;ll probably run.&rdquo;\r\nMavericking won his maiden by more than three lengths, and was gaining late on talented turfer Perragaux in a Dec. 18 allowance race. Pessin said Mavericking will race in a shadow roll for the first time Sunday in an effort to keep the colt more focused.\r\n&ldquo;He&rsquo;s still a little green,&rdquo; said Pessin. &ldquo;He still kind of gets in and out a little bit, plays around.&rdquo;\r\nThere are high hopes for Prime Cut, a son of Bernstein purchased for $475,000 as a yearling. Prime Cut is owned by Courtlandt Farm and trained by Neil Howard, the same connections that sent Machen out to a fast debut sprint score last Sunday. Prime Cut, Howard said last week, has been regarded as a more substantive prospect than Machen, which suggests his ceiling is high. Making his second start, Prime Cut was clearly best in a Dec. 12 maiden sprint race in New Orleans, and should only improve with added distance.\r\nRain also threatens to disrupt Sunday&rsquo;s other entry-level turf allowance, race 8, this one for older fillies and mares at 1 1/16 miles. Silver La Belle is one horse who should contend on either surface. She finished second last out in the Pago Hop on grass, and was third two back in a Churchill Downs dirt route.
