MIAMI - Steve DiMauro knows he doesn't have the numbers to compete for leading training honors here this summer, especially considering he has his stable split again this season between Calder and Monmouth Park. But DiMauro is enjoying his current reign atop the local standings, having won five races during the open three weeks of a meet that will continue through mid-October.

Philadelphia Park plans to add Friday twilight cards and reduce live racing on Sundays during a 10-week period this summer.

Starting Friday, May 28, and continuing through the end of July, live racing will be held Friday, Saturday, Monday, and Tuesday.

The Bensalem, Pa., track experimented with twilight cards last summer and it turned out to be popular.

Lone Star Park officials will seek approval at a stewards' hearing Thursday for new procedures for horses loaded into the starting gate wearing blankets. The move comes after an incident that led to Saturday's fourth race being declared a no-contest. One starter, Rocks and Rings, broke from the gate in the blanket she was loaded in and shed it while crossing over to the lead in the first turn of the one-mile race.

The blanket flared out before sliding off her and hitting the ground, with one of the horses hitting the rail and another jumping over the equipment as it fell.

The meet that gets under way Saturday will be unlike any other at Monmouth. The core summer season will offer 50 days of racing with purses averaging $1 million a day, the highest in North America. First post will be 12:50 p.m. for the 12-race card.

The 1 1/16-mile race is one of six statebred stakes on the first major card of the meet at Louisiana Downs.

MIAMI - Sweet Repent, who went to the farm this winter riding a five-race winning streak, posted her first work on the comeback trail here Saturday, breezing an easy three furlongs in 38.60 seconds.

Trained by David Braddy, Sweet Repent steadily ascended the filly-and-mare handicap division, closing her 3-year-old campaign last year with four straight victories at Calder, including a nose victory in the Grade 3 Stage Door Betty Handicap in late December. She returned five weeks later and dominated the Sunshine Million Distaff at Gulfstream Park before going to the farm.
