Bowing out: San Felipe runner-up Jaycito will miss the Kentucky Derby, trainer Bob Baffert confirmed after much speculation of the sort. The colt, a Grade 1 winner as a juvenile, has been battling a foot bruise; he hasn't worked in three weeks and missed planned preps in the Santa Anita Derby and Lexington. The colt will now point for the Belmont, a race his wire, Victory Gallop, won in 1998. Jaycito's defection will allow Tampa Bay Derby winner Watch Me Go into the field; next on the list to get in is Florida Derby runner-up Shackleford.

Macho move: Working over a muddy track immediately after the break, Risen Star winner Mucho Macho Man went a relaxed seven furlongs in 1:29.40. The move came under Rajiv Maragh, who has the mount in the Derby. He'll work five furlongs on Sunday in his final move before the Derby.

Cheers: Gotham winner Stay Thirsty, in company with older stakes winning stablemate Bridgetown, went five furlongs in :59.92 at Churchill Sunday morning. The Bernardini colt went in splits of :11.56, :23.22 and :35.06. After finishing about a neck in front of Bridgetown with some urging, he galloped out in 1:15.06. Three-time Derby winner Calvin Borel, who doesn't yet have a Derby mount, was aboard for the work; trainer Todd Pletcher, who partnered with Borel to win the Derby last year with Super Saver, says he hasn't officially selected a rider yet. Also available is Ramon Dominguez, who rode Stay Thirsty to the Gotham win.

Notes: Eclipse champion Uncle Mo galloped a mile and a half over the muddy track as he continues to prepare for Tuesday morning's breeze. ... Also galloping Sunday were juvenile graded winner Santiva, Spiral runner-up Decisive Moment and Santa Anita Derby winner Midnight Interlude.
