Which sister's turn is it in Old South?


Due to Win and Due to Win Again, half-sisters who each won a stakes in their last start at Louisiana Downs, are both shooting to win the Bossier City, La., track's $50,000 Old South Handicap for a second time Saturday.

Due to Win Again won the 1 1/16-mile turf race for fillies and mares last year, and Due to Win captured it in 1999.

The siblings do not race together often, but when they do the results have been good for their breeders and owners, Howard and Penny Scarberry. The mares are also trained by Howard Scarberry.

"They ran together in a stakes last year, and they finished first and second," said Penny Scarberry. "We're hoping for a rerun. That was pretty awesome."

Due to Win Again, who is 6, seems like the most probable winner of the two on Saturday. She is the turf specialist, with six wins on the grass. Of those wins, three came at Louisiana Downs.

She won the $50,000 Honeymoon over the local course May 15, then came back to run seventh in the Grade 3, $200,000 WinStar Distaff at Lone Star Park. That race seems like a throwout. Scarberry said the consensus was Due to Win Again did not take to the course in the WinStar.

She has since been training well at Louisiana Downs and with her versatile style can race either on or off the pace Saturday. Due to Win Again will be ridden by Luis Quinonez.

Due to Win, who is 9, was retired and bred last year to Silky Sweep, but she did not get in foal and her connections decided to race her again this year. In her most recent start, she won the $50,000 Fleur de Lis on dirt at Louisiana Downs on May 30.

Scarberry said Due to Win has been training on the couple's farm this year instead of being based at a track. "She seems like she's real happy," she said, "so we decided to go ahead and still run her."

Due to Win, who is by Lac Ouimet, has won 11 of 80 starts and $415,619. She is out of the His Majesty mare Duenita, who is also the mother of Due to Win Again. Due to Win Again is by Pioneering and will be ridden by Corey Lanerie.

Others of note in the Old South include I'm the Business, who makes her second start back from a seven-month layoff for leading trainer Cole Norman; Blue Guru; and Mexican Moonlight.
