Two of the top three finishers from the Kentucky Derby posted good works in recent days and appear to be sitting on go for the Preakness.

Authentic, who fended off Tiz the Law to upset the Kentucky Derby, worked five furlongs in 59 1/5 seconds, the fastest of 38 at the distance over a Churchill Downs surface he clearly relishes.

“Everything is all systems go for the Preakness,” trainer Bob Baffert said following the work.

The same looks to be true for Mr. Big News, the longshot who made a big middle move before flattening out to be third in the Run for the Roses. He had what trainer Bret Calhoun termed a “very sharp” workout Friday morning at Churchill, cruising a half-mile in 48 4/5 seconds. “It was what we wanted or better,” Calhoun said.

The same could not be said of the beaten Derby favorite, Tiz the Law, however. He has yet to work since his runner-up finish in the Derby, and owner Jack Knowlton of Sackatoga Stable, said his New York-bred son of Constitution came out of the Derby “a little more worse for the wear than he typically does.”

Saying that he thinks that Tiz the Law and the Churchill Downs racing strip don’t quite agree with each other, Knowlton indicated that a work in the early or middle part of the coming week would determine whether Tiz the Law continues to Baltimore, or trains up to the Breeders’ Cup in November at Keeneland.

Two new names emerged as possible Preakness runners this week.

Trainer Kenny McPeek said Swiss Skydiver, his Grade 1-winning filly, was under consideration for the Preakness.

“It’s going to depend on who shows up,” McPeek said. McPeek is also looking at a pair of Grade 1 events for older fillies and mares during the upcoming Keeneland meet and indicated that, were Tiz the Law to skip the Preakness, that might lead him to head to Baltimore.

One new name who appears more definite is Liveyourbeastlife. The Ghostzapper colt, a two-time winner from eight starts, was a closing second in the Grade 2 Jim Dandy September 5 and had a sharp five-furlong move September 17.

“He breezed really well today,” said Abreu of the breeze in company with New York-bred Freaky Styley [59.80]. “He went in 59 and 4 which is something he’s never done before. We’re going to take a shot.”

Liveyourbeastlife will need to be supplemented to the Preakness for $25,000.

On the flip side, it now appears that King Guillermo, entered but then scratched from the Kentucky Derby, will not make the Preakness, either. He joins another Derby scratch, Finnick the Fierce, on the Preakness sidelines, as well as a couple of runners who figured to be longshots if they posted in Lebda and Azul Coast.
