Multiplier was the last of the Preakness contenders to hit the Pimlico Race Course surface for the first time, galloping 1 1/4 miles Thursday morning under the guidance of trainer Brendan Walsh.
The son of The Factor arrived in Baltimore on Tuesday and had a planned walk day Wednesday.
"I’ve had a couple of Breeders’ Cup runners, but this is my first Classic runner, so it’s very special,” Walsh said. “This is where every trainer wants to be. Hopefully, it’s the first of many. You’d like to have horses like this every year.”
Multiplier drew the No. 1 post, but that wasn't a problem in the the Grade III Illinois Derby, where he also drew the rail. “So I don’t think it’s going to make that much of a difference with 10 runners,” Walsh said.
War Emblem, in 2002, is the last Illinois Derby winner to capture the Preakness.
Cloud Computing will be Chad Brown's first-ever horse in the Preakness, but the Eclipse Award-winning trainer has been hands-off so far this week.
Brown, based in New York, sent traveling assistant Jose Hernandez to Baltimore this week to supervise the training of four horses, including Cloud Computing, the third-place finisher in the Grade II Wood Memorial.
Cloud Computing is owned by Seth Klarman, the chief executive and portfolio manager of the Boston-based Baupost Group. Klarman spent part of his childhood in Baltimore, a few blocks from Pimlico, the son of a Johns Hopkins Bloomberg School of Public Health epidemiologist and Johns Hopkins public health administration professor.
