DEL MAR PICK 4 (RACES 7-10) RACE 7 KEY's - MOTOWN MEN, SUMERIAN, SOMETHINGS UNUSUAL, MAMBO MAN B's - SWIFT EAGLE, SAMURAI WARRIOR C's -  TOM’S TRIBUTE, AMERICAN TANKER, BIO PRO Don't have a good feel here but am against a couple of shorter horses on the Morning Line so will spread liberally. RACE 8 KEY's - PAYNTER, LIAISON B's - KETTLE CORN, CLUBHOUSE RIDE Will center this race around the two Baffert runners, #3 PAYNTER, probably the best horse, but could regress second start back after the extended layoff; and #4 LIAISON, who has improved this year and should be right there if his stablemate falters. RACE 9 KEY's - SOUTH FLOYD, SEVEN BRIDGES C's - LIFE A RILEY Centering my play around two who exit much tougher races than many of these, #1 SOUTH FLOYD, who is one of the couple in here with speed and should be prominent throughout, and #9 SEVEN BRIDGES who’s two races here last summer were solid and just may be faster than everyone. RACE 10 KEY's - PASSIONATE DIVA, LAKE MARACAIBO B's - CHARM CATCHER, WINNING RHYTHM Like the Euro import, PASSIONATE DIVA, who gets Lasix for stateside debut; nicely bred filly but stuck on the outside; and LAKE MARACAIBO, who is on the AEs, but if she draws in has races fastest enough to break her maiden here.
