Quality Road's winning Beyer Speed Figure in the Florida Derby has been substantially upgraded - from 103 to 111. The change was made as part of an overall revision of the 1 1/8-mile races at Gulfstream Park.

HALLANDALE BEACH, Fla. - Not that Jimmy Jerkens has or likely will ever need any help when it comes to training Quality Road into this year's Kentucky Derby. Obviously he's done just fine up to this point, having won both the Fountain of Youth and Florida Derby. But should Jerkens be compelled to seek a little counseling somewhere along the Derby trail, all he needs to do is turn to Dad for some fatherly advice.

Dad is none other than Hall of Fame trainer Allen Jerkens, who knows a thing or two about winning big races and has already been to the Derby on three occasions.

"At the three-eighths pole, when I turned for home, I said, 'They're not catching me,' " he said on the Santa Anita backstretch Thursday.

Through the lengthy stretch, Gryder knew he was pulling away and was able to enjoy the moment.
