The speed battle trainer Tim Ritvo hoped would develop to enhance stretch-running R Obsession's chances in Saturday's $100,000 at Calder never materialized. But in the end it didn't matter, as R Obsession finished full of run along the hedge to easily wear down pacesetter Our Exploit en route to a 1 1/4-length victory in the 7 1/2-furlong stakes for 3-year-old fillies.

It took Play Bingo nearly nine months after his first start to finally win a race. Once he learned how it's done, Play Bingo hasn't been beaten.

The 3-year-old Play Bingo extended his winning streak to five races when he drew off to a 5 1/4-length victory in the $100,000 at Pimlico.

It was the first stakes victory for the John "Doc" Fisher-trained Play Bingo, who needed three starts beyond his career debut in October 2003 to win his maiden in July at Delaware Park.

One Smooth Ride ($21.40) closed strongly in the stretch under jockey Constant Montpellier to capture the $137,500 at Woodbine.

One Smooth Ride came from last in the five-horse field, but was never more than five lengths off the pace in the 1 1/16-mile event for 2-year-olds. Accountforthegold set fractions of 23.29 and 47.81 seconds before being joined on the lead by Radical Right, favored Kerrobert, and The Finagler, who had bumped Kerrobert hard on the first turn while rank.

Marketable overcame a bump at the break and then rallied to collar the dueling leaders in the final strides to score a neck victory in the $40,000 Glacial Princess Stakes for 2-year-old Ohio-bred fillies at Beulah Park.

Marketable ($6.80) was ridden to victory by Hector Rosario Jr. and is trained by Tim Hamm. Marketable clocked the mile and 70 yards in 1:49.92. Cloudy Forty Nine finished second.

MIAMI - The Silver Wagon is about ready to roll. The Grade 1 stakes winner worked five furlongs in 1:02 over a cuppy racetrack here Saturday morning and may be as little as three weeks away from launching his comeback.

Blazing Exploit improved his career record to 3 for 4 when he drew out to a six-length win over Camsdancer in the $40,000 Delta Beau at Delta Downs. It was another 6 1/2 lengths back in third to Get Myself a Gun.

Blazing Exploit ($4.40) was pushed along early by Mr. Excellent, and ran the opening quarter-mile of the five-furlong race for 2-year-olds in 22.60 seconds. Blazing Exploit increased his half-length advantage from there, and went on to cover the distance in 59.57 seconds.

Honor the Flag remained perfect in two career starts when she rallied to overtake pacesetter Wind Twister by 4 1/4 lengths in the $40,000 E.L. Gaylord Memorial at Remington Park. It was another 1 3/4 lengths back in third to Proper Wildcat.

Honor the Flag ($15.40) settled in fifth early, while Wind Twister led the field through fractions of 22.09 seconds for the opening quarter-mile and 45.30 seconds for a half. Honor the Flag overtook the leader in the stretch and increased her advantage to the wire, covering the 6 1/2 furlongs for 2-year-old fillies in 1:18.04.

EAST BOSTON, Mass. - Jockey Winston Thompson will prove the age-old sports axiom that it is better to have momentum at the end of a season than the beginning when he wraps up his second career riding title at Suffolk Downs on Monday.

Surfing a wave of 35 wins since the start of November, including four four-win days, Thompson flew past Joe Hampshire, the winner of the last eight riding titles here, last Tuesday to take the lead in the standings. Through Friday, Thompson had ridden 151 winners for the season, eight more than Hampshire.

Yougottawanna ($13.80) got a perfect stalking trip, taking over near the quarter pole, and then held off odds-on Adreamisborn to win the Forty-Niner Handicap at Golden Gate Fields.

Yougottawanna, claimed for $50,000, then re-claimed for $80,000 earlier this year by trainer Jerry Hollendorfer, sat off Kristine's King through moderate fractions in the 1 1/16-mile race. He took the lead on the second turn and opened up into the stretch.

Cajun Beat, the winner of the 2003 Breeders' Cup Sprint, won his first turf stakes with an impressive late rally in Friday's $150,000 at Hollywood Park.

The win was Cajun Beat's first since the Grade 3 Mr. Prospector Handicap at Gulfstream Park in January, and first since joining Bobby Frankel's stable in the summer. Cajun Beat was previously trained by Steve Margolis.

Cajun Beat finished fifth in the 2004 Breeders' Cup Sprint last month at Lone Star Park.

In the Grade 3 Turf Express, Cajun Beat ($6.40) ran 5 1/2 furlongs on turf in 1:02.08.
