Black Seventeen (Tr: Brian Koriner; ex. rider: Colleen Hartford) - Black Seventeen worked 4f Monday morning at about 8:45 in a drill that will be his final major exercise for Saturday's Sentient Flight Group Breeders' Cup Sprint.

With trainer Brian Koriner watching from aboard his pony, and assistant trainer Colleen Hartford aboard, the 4yo son of the 1988 Breeders' Cup Juvenile winner Is It True went in 47 4/5 and drew praise for it afterward.

"That's a nice work for him," the former quarter-horse trainer Koriner said back at Barn 17. "He's a big, heavy horse who is a bit lazy in the mornings and you've got to get him to work hard to get things done. Colleen has been telling me he really likes this track. He's done well on it and we're hoping for the best Saturday.

"That race (Sprint) is such a tough event. There are so many good horses in there; so many fast horses. I know my horse is fast, but I know he's in tough. But he's doing good and we'll be in there trying. He might be good enough."

Black Seventeen, who was the longshot winner of the Vosburgh in New York on Sept. 27 on a "sloppy" track, will be kept with his regular rider, Clinton Potts, for the six-furlong Sprint.

Cost of Freedom (Tr: John Sadler; ex. rider: Dana Barnes) - Gary and Cecil Barber's Cost of Freedom jogged 1m on the main track Monday at Santa Anita with exercise rider Dana Barnes up for trainer John Sadler.

Tyler Baze, who has ridden the 5yo gelding to three consecutive victories, will have the mount in Saturday's Sprint. Baze has not won a Breeders' Cup race.

Cost of Freedom, who has been stabled at Santa Anita since the end of the Del Mar meeting in early September, had his final work for the Sprint last Saturday, a 5f move in 59 2/5.

Fabulous Strike (Tr: Todd Beattie) - Following a romping win in last year's Vosburgh, Fabulous Strike appeared prime for a big run in the Breeders' Cup Sprint, but just a week before the race he came down with a severe lung infection.

"It popped up clear out of the blue," said trainer Todd Beattie, who lost out on a chance at running his first Breeders' Cup horse. "We were stuck in traffic for six to seven hours on the way back from Belmont (after the Vosburgh) and the extra stress may have contributed to it. It was a huge disappointment."

With an eye on this year's Sprint, the 5yo gelded son of Smart Strike returned to battle in an ungraded stake at Delaware Park on June 21, defeating just two overmatched rivals as the 1-9 favorite.

"We wanted to run him against softer competition in that first race," Beattie said. "Our plan was to run back in the Vanderbilt, but he ripped off a piece of his foot in the frog area and he missed 60 days."

Fabulous Strike returned in the Vosburgh, and after battling a fast pace over a sloppy track, he settled for second behind the longshot Black Seventeen.

"We were very pleased with the effort," Beattie said. "He was a half a head away from winning. He fended off quite a few challenges in the race, tried hard, and actually galloped out in front."

Regular rider Ramon Dominguez is named for Saturday's Sprint.

Fatal Bullet (Tr: Reade Baker) - Fatal Bullet walked on Monday after working 5f in 1:01 2/5 at Santa Anita on Sunday under jockey Erico Da Silva, who will ride him in the Sprint.

"He's settled in and is doing really good here," said Casse Garcea, assistant to Reade Baker. "At home he can be a little bit of a hard head, but the change of scene has been good for him. We shipped in early (from Canada) to get him and (stablemate) Bear Now (Ladies' Classic) acclimated and they have."

First Defence (Tr: Robert Frankel; ex. rider: Goncalino Almeida) - Juddmonte Farms' homebred 4yo was a walker Monday morning after firing a bullet 5f of 57 4/5 with jockey Goncalino Almeida aboard.

"I didn't want him to go that fast," said the colt's trainer, Bobby Frankel, standing trackside at Santa Anita Monday morning. "I told him to work him in a minute. But what are you going to do? I'll tell you, though, I've been watching these sprints for a long time and it seems to me the horses that work fast win them. I remember when I ran Squirtle Squirt in New York and won. He worked 45 coming up to that race (45 4/5)."

First Defence won the Forego at Saratoga in August, then finished last in the Vosburgh at Belmont in September in the mud.

"I've got to think the sloppy track did him in in that last one," Frankel said. "That won't be an issue here."

The colt will be reunited with Javier Castellano for the Sprint. The New York-based rider has handled him in 11 of his 13 starts.

In Summation (Tr: Christophe Clement) - After having to miss competing in the Sprint at Monmouth Park last year, In Summation is healthy and primed for this year's edition.

"He's been here since July and he's doing very well," said Nicholas Balachard, assistant to trainer Christophe Clement. "He excels on synthetic tracks."

Clement decided not to run In Summation, who had a history of trouble with his feet, after his final workout for the 2007 Breeders' Cup, which was run over a dirt track. But there are no problems this year and John Velazquez has accepted the mount.

J Be K (Tr: Steve Asmussen) - Trainer Steve Asmussen reported that Zayat Stables' 3yo J Be K will not contest the Sprint.

"He will not run," Asmussen said. "He has not come back to himself since running (fifth) in the Vosburgh (Sept. 27). It's disappointing. We felt very good about him this summer. We were going to work him this morning, but instead we're going to give him some time. His last race kind of shook him up a bit."

Midnight Lute (Tr: Bob Baffert; ex. rider: Janell Gruss) - Defending Breeders' Cup Sprint winner Midnight Lute worked 4f in 47 under exercise rider Janell Gruss on Monday morning at Santa Anita.

"He went very smooth, very nice," trainer Bob Baffert said. "I got him galloping out the five-eighths in 59 3/5."

Owned by Mike Pegram and Watson & Weitman Performance LLC, Midnight Lute will be paired with Garrett Gomez in the Sprint. Gomez rode Midnight Lute to a 4 ¾-length victory in the slop in last year's Sprint at Monmouth Park.

Midnight Lute has run only once in 2008, a 10th-place finish in the Pat O'Brien at Del Mar on Aug. 24. He grabbed a quarter in the race and has been wearing a protective plate since.

"The plate will come off before Saturday," said Baffert of Midnight Lute, who has put together a string of bullet works at Santa Anita since returning from Del Mar."That surface down there was just too hard for him," Baffert said. "He was just sour down there and he really picked up once he got on this surface. He has thrived on it."

Sing Baby Sing (Tr: Jack Bruner) - Phoenix winner Sing Baby Sing galloped 1m at his Remington Park base on Monday and will ship to California on Wednesday. In his final workout, the Unbridled's Song horse breezed 4f in 48 3/5 on Saturday.

"I'm very pleased with how he's been doing," said trainer Jack Brunner, who will be saddling his first Breeders' Cup starter. "He came out of the Phoenix just fine and everything's a go."

Justin Sheppard, who has ridden Sing Baby Sing in every start since June 2006, will have the mount again on Saturday.

Street Boss (Tr: Bruce Headley) - The runner-up in Oak Tree's Ancient Title galloped 1 ¼ m Monday and will do the same on Tuesday in preparation for a 3f workout Wednesday for trainer Bruce Headley as the 4yo Street Cry colt heads toward the Sprint.

Headley said he is quite happy with the colt's preparation, mentioning that his runner seemed to be just one jump way from winning the 6f Ancient Title.
