DEL MAR TRIFECTAS, SUPERFECTAS (RACE 7) KEY's - Warren's Dixi Belle B's - Tickle Again, Tribal Valentine C's - Van Dien Avenue, Sri's Red, St. Malo's Gate The homebred Warren's Dixi Belle (#4) showed noticeable improvement when making her second start after being regrouped by underrated trainer (Gutierrez); now stretches out off that encouraging sprint effort while moving over to the grass and drawing favorably; underrated jock (Delgadillo) helps with the price. Key her first and second in vertical plays when using pricier entries such as Tickle Again (#1) and Tribal Valentine (#3) while also salting in some tertiary keys in this sort of way: 4 with 1/3 with 1/3/6/7/8, and so forth.
