Champion sprinter Runhappy turned in his first serious workout of 2016 on Thursday, covering three furlongs in 34 4/5 seconds in the predawn darkness at Keeneland.

Trainer Laura Wohlers said her team caught Runhappy, who shipped in to breeze from his base at the Thoroughbred Training Center in Lexington, Ky., and exercise rider Marcus O’Donnell galloping out in 46 seconds and 59.

String King is set to make a second start at the Louisiana Downs meet next month in the $75,000 Unbridled, according to Charlie Smith, his breeder, owner, and trainer. The 1 1/16-mile turf stakes will be run on the Super Derby undercard Sept. 10. String King won the race a year ago after capturing his third straight Louisiana Cup Turf Classic.

SARATOGA SPRINGS, N.Y. – The Grade 1 Personal Ensign on Saturday’s Travers card here brings together the best of the filly-and-mare route division on the East Coast.

Cavorting, the winner of the Grade 1 Ogden Phipps at 1 1/16 miles, will attempt to stretch out yet again as she tries 1 1/8 miles for the first time. She will break from the outside in the five-horse field under Javier Castellano.

SARATOGA SPRINGS, N.Y. – The best story on Saturday’s 13-race Travers card is the return of Lady Eli, the undefeated filly who overcame a serious bout of laminitis to make it back to the races.

Unraced since winning the Grade 1 Belmont Oaks on July 4, 2015, Lady Eli will take on seven opponents in the Grade 2, $400,000 Ballston Spa Stakes. The 1 1/16-mile turf race for fillies and mares is race 12, immediately after the Travers.

SARATOGA SPRINGS, N.Y. – The Travers, with its 14-horse field that includes two classic winners, is obviously the focal point of Saturday’s 13-race program at Saratoga. But there is a terrific undercard in support, featuring top horses such as Flintshire, Lady Eli, and a sensational quintet in the Grade 1 Personal Ensign.

Jockey Colby Hernandez has established himself as the dominant rider at Evangeline Downs in Opelousas, La., where he is poised to lock up his fourth title when the meet closes Saturday night. Hernandez had a 12-win lead over Diego Saenz heading into Wednesday’s card.

Hernandez, 27, is a native of Lafayette, La., whose career path was something of a given as the son of a jockey, Brian Hernandez Sr. In addition, brother Brian “B.J.” Hernandez Jr. is an Eclipse Award-winning rider based in Kentucky.

DEL MAR, Calif. – Dalmore, who finished fifth in the $1 million Pacific Classic last Saturday, is likely to return to the 3-year-old division for the $400,000 Super Derby at Louisiana Downs on Sept. 10, trainer Keith Desormeaux said on Wednesday.

The Grade 3 Super Derby is run at 1 1/8 miles.

DEL MAR, Calif. – In the nearly four years since Vyjack won his debut, the gelding has won stakes on dirt in sprints and around two turns, started in two Triple Crown races, finished second in two graded stakes on turf, and earned more than $1.1 million.

On Saturday, Vyjack will start in the $200,000 Pat O’Brien Stakes at seven furlongs on dirt at Del Mar. The O’Brien Stakes will be Vyjack’s 26th start and his first in California. It also will be his first start at less than a mile since a third in the Grade 1 Forego Stakes at Saratoga in August 2014.

SARATOGA SPRINGS, N.Y. – Kharafa has been racing at New York Racing Association tracks since 2011 and has been a mainstay in the New York-bred turf division since 2013. He’s won 7 of 21 starts at Belmont Park and is 2 of 4 at Aqueduct. He has not done as well at Saratoga, however, and has yet to finish better than third in four tries.

Kharafa has won at least one stakes a year in New York from 2013 to 2015. He will try to extend his streak and break into the Saratoga win column on Friday in the $150,000 West Point, a 1 1/16-mile turf race for statebreds.

SARATOGA SPRINGS, N.Y. – If nothing else, the Travers has not lacked for drama over the last decade. In seven of the last 10 runnings, the margin of victory has been less than a length.

Longtime owner and breeder William S. Farish has been on the wrong end of two close Travers finishes with Grasshopper, who fell a half-length short to Kentucky Derby winner Street Sense in 2007, and Mambo in Seattle, who got beat a nose by Colonel John in 2008.

“I remember them very well,” Farish said this week. “I wasn’t happy at the time, but I’m certainly over them and pushing forward.”
