ARCADIA, Calif. - Power Broker, unraced since a fifth-place finish in the Breeders’ Cup Juvenile in November, worked a half-mile in 47.40 seconds at Santa Anita on Sunday, his final major workout before a start in Saturday’s $750,000 Santa Anita Derby. “I liked what I saw,” trainer Bob Baffert said. “He didn’t get tired.” Owned by Gary and Mary West, Power Broker has 1 win in 5 starts and earnings of $242,600. A colt by Pulpit, Power Broker’s lone victory came in the Grade 1 FrontRunner Stakes over 1 1/16 miles here last September. [ROAD TO THE KENTUCKY DERBY: Prep races, point standings, replays] Power Broker will make his first start over 1 1/8 miles in the Grade 1 Santa Anita Derby, the top California prep for the Kentucky Derby on May 4. Baffert is hopeful that Power Broker can be effective in longer races. “This time of year, it’s who can get the distance,” he said. Rafael Bejarano, the leading rider at this meeting, has the mount on Power Broker. Bejarano was aboard for all five of Power Broker’s starts in 2012. Baffert plans to have three starters in the Santa Anita Derby, along with Flashback, who won the Grade 2 Robert Lewis Stakes on Feb. 2 and the runner-up to Santa Anita Derby hopeful Hear the Ghost in the Grade2 San Felipe Stakes on March 9; and Super Ninety Nine, who won the Grade 3 Southwest Stakes at Oaklawn Park on Feb. 18 but was fifth in the Grade 2 Rebel Stakes there on March 16. Other candidates are Tiz a Minister and Goldencents, who were third and fourth in the San Felipe, the maiden race winner Storm Fighter; and Dirty Swagg, who finished fifth behind Goldencents in the Grade 3 Sham Stakes on Jan. 5.
