Jockey C.J. McMahon, who briefly tried the Kentucky circuit in 2013, is back in town, this time hoping to become a more permanent fixture.

McMahon, 22, rode primarily in Texas, Oklahoma, and his native Louisiana in recent years before moving in April to Gulfstream Park, where he had 25 wins from 276 starters (9 percent).

“I believe he belongs here as much as anyone,” said his new agent, Joe Santos, whose former client Didiel Osorio has been suspended indefinitely on suspicion of carrying an electrical device in a race last Friday at Indiana Grand.

No one is quite sure whether it’s a record, but when Sue Martin, 63, won the first race Sunday at Ellis aboard Golden Fire Fly, she might have become the oldest female jockey ever to win a race in North America.

News archives say Diane King also was 63 when she rode a winner at Thistledown in August 2013, when it is believed she set the record in that category.

Miss Temple City is considered a possible starter by trainer Graham Motion for the $350,000 Kentucky Downs Ladies Turf on Sept. 9, although he has not ruled out another race elsewhere to use as a prep for the Oct. 7 Shadwell Turf Mile at Keeneland.

If the 5-year-old mare does in fact make the trip from her Maryland base, surely she will be the most accomplished horse to ever set foot on the Kentucky Downs course. She’s a three-time Grade 1 winner and an earner of more than $1.4 million, with two of those Grade 1 victories coming against males at Keeneland.

Ten City, the colt who defeated Copper Bullet in the Bashford Manor Stakes at Churchill Downs, will make his next start Sunday in the $75,000 Ellis Park Juvenile in western Kentucky.

“He needs to run,” said trainer Kenny McPeek, who initially intended to wait until the Sept. 16 Iroquois at Churchill for the colt’s next race. “He’s been training, training, training, and I finally decided this is the best way to go.”

DEL MAR, Calif. – Irish Freedom was so highly regarded that he ran in the Santa Anita Derby in only his third start, and his second off a layoff, earlier this year. He was off for four months after that race, but returned with an impressive score against allowance company Sunday.

“He had been working really well,” trainer Bob Baffert said. “He needed time off after the Santa Anita Derby because he got real sick. The very next day, he had a temperature of 103 or 104.”

DEL MAR, Calif. – Bal a Bali and Om are expected to meet Sunday in the Grade 2, $200,000 Del Mar Mile on turf, and each turned in a short, sharp workout on the dirt on a drizzly Tuesday morning in their final serious preparations for the race.

Om, trained by Dan Hendricks, worked three furlongs in 36.80 seconds. Bal a Bali, trained by Richard Mandella, went a half-mile in 47.40.

DEL MAR, Calif. – The Pacific Classic came into being in 1991, seven years after the first Breeders’ Cup. This year marks the first time that the Breeders’ Cup will be run at Del Mar, and that is one of the reasons the Pacific Classic this Saturday is so vitally important for the participants, especially Arrogate, for it mirrors the Breeders’ Cup Classic on Nov. 4, a 1 1/4-mile dirt race at Del Mar.

DEL MAR, Calif. – Led by Arrogate, a field of six or seven was expected to be entered on Tuesday morning for the Grade 1, $1 million Pacific Classic on Saturday at Del Mar, posts for which were to be drawn late Tuesday afternoon at the local restaurant The Brigantine.

ARLINGTON HEIGHTS, Ill. – The morning after his unprecedented sweep of the two marquee races at Arlington Park, trainer Chad Brown was fondly reminiscing about the days when he worked in Southern California for his late mentor, Bobby Frankel.

“We’d be at Hollywood Park in the middle of the winter and he’d look at a horse and say, ‘That one will fit in the Beverly D.,’ or ‘That one, he’s my Million horse,’ ” said Brown, briefly mimicking Frankel’s heavy New York accent. “He was always thinking about those races.”

SARATOGA SPRINGS, N.Y. – Uni, third in the Grade 1 Belmont Oaks behind stablemates New Money Honey and Sistercharlie, worked five furlongs in 1:03.15 Monday morning in preparation for a start in Saturday’s Grade 2, $300,000 Lake Placid Stakes at Saratoga.

Uni worked in company with Roca Rojo, and the two broke off slowly, going an opening quarter in 27.02 seconds. They finished in 36.13 and galloped out six furlongs in 1:16.30.

“They broke off a little too slow, but they finished good,” trainer Chad Brown said.
