Saturday's 144th running of the Preakness S. (G1) drew a field of 13 3-year-olds vying for the second jewel of the Triple Crown, with Bob Baffert's Improbable, in post 4, made the 5-2 morning line favorite.

After a drama-filled Kentucky Derby (G1) that ultimately resulted in a fourth-place finish for Improbable, the Preakness has only four Run for the Roses returnees, including the highly-regarded War of Will, who, like he did in the Derby, drew post 1 for Saturday's 1 3/16-mile contest.

Improbable will be ridden for the first time this weekend by Mike Smith. Prior to his last start, the chestnut colt had never finished worse than second in five starts, with wins in the Los Alamitos Futurity (G1) and Street Sense S. 

"I feel like we're favored by default this year," said Elliott Walden of WinStar Farm, who co-owns Improbable with China Horse Club and Starlight Racing . "But this horse has a good resume. He ran very well in the Derby without hitting the board." 

Baffert is going for a record eighth win in the Preakness, the last two (Justify in 2018 and American Pharoah in 2015) both were Triple Crown winners.

The Preakness will be shown on NBC-TV, with an approximate post time of 6:48 p.m. ET.
