Itsmyluckyday worked a half-mile in :48 4/5 Saturday morning at Calder for trainer Eddie Plesa Jr., his first workout since his stunning two-length victory over previously undefeated juvenile champion Shanghai Bobby in the Grade 3 Holy Bull at Gulfstream Park.

"It was exactly what I was looking for," Plesa said later in the morning.

"I got him galloping out (five furlongs) in 1:01. He's right on schedule. He'll probably work about every seven days, although I might change it up on him one of those times with an easy mile work. I haven't decided."

Regular exercise rider Isidorio Ramos was in the saddle for Saturday's move.

The son of Lawyer Ron won the one-mile Gulfstream Park Derby on New Year's Day before the 1 1/16-mile Holy Bull and is on target for a rematch with Shanghai Bobby in the Grade 1, $1 million Florida Derby at 1 1/8 miles on March 30.
