Hot Pace, Talented Field for 138th Kentucky Derby Hot pace. Muggy day. One of the deepest, talented fields in years. A delicious stew with all the ingredients for an unpredictable Kentucky Derby. The 20-horse field for Saturday's race is so stacked that unbeaten Gemologist is no better than third choice on the morning line. In other years, the colt would be the talk of the Derby. In this one, early favorites Bodemeister and Union Rags have grabbed the spotlight. Still, some very talented colts could go off at big odds - I'll Have Another at 12-1 or, at 15-1, Take Charge Indy, whose jockey Calvin Borel has brought home long-shot winners twice in five years. "This is the best bunch I've seen in a long time," four-time Derby-winning trainer D. Wayne Lukas said. I was out there riding next to some of them, and let me tell you, this is a hell of a group. Lukas will saddle one of the longest shots, 50-1 Optimizer. "History tells us that you can't throw anyone out," said Todd Pletcher, a former Lukas assistant who has two Derby starters including Gemologist. There have been some winners the past few years that have been way down everybody's depth charts. Some of the strongest contenders - Hansen, for example - have had the most success running at or near the pace. But their task is complicated by the presence of speedball Trinniberg, who could prove to be enough of a pest on the front end to compromise any horse willing to keep pace with him.

Three-time Derby winner Bob Baffert, who trains 4-1 favorite Bodemeister and long shot Liaison, called it "one of the toughest Derbys I've been in probably the last 10 years." "I've brought some really good horses here, and they were the best horse, but they got beat," he said, referring to Lookin At Lucky, the 2010 race-day favorite who was trapped on the rail and finished sixth. In 2001, his heavy favorite Point Given wound up fifth. I don't want to get myself too pumped up. Even my son, Bode, doesn't want to talk about it," he said. The 7-year-old namesake of Bodemeister is worried. Upon learning the colt was headed to the Derby, he asked his dad, "Well, what if he loses?" "It's a little extra pressure for me to make sure that he runs well," said Baffert, who had a medical scare in March when he was hospitalized with a heart attack in Dubai. Bodemeister, ridden by Hall of Fame jockey Mike Smith, goes into the starting gate staring down 129 years of Derby history. The last horse to win without racing as a 2-year-old was Apollo in 1882. Union Rags, the 9-2 second choice ridden by Julien Leparoux, is the best horse trainer Michael Matz has brought to the Derby since he won with undefeated Barbaro in 2006. "I was lucky enough once," he said. It's hard to believe you can get lucky twice. Matz trains the strapping colt for Phyllis Wyeth, the former steeplechase rider who was paralyzed from the waist down in a 1962 car accident and gets around in a wheelchair. She is married to painter Jamie Wyeth, whose father was the renowned artist Andrew Wyeth. Gemologist, undefeated in five races, is trained by 2010 Derby winner Pletcher, yet he's been overshadowed by the other entrants since arriving late in Louisville and getting most of his training in Florida.
