Testing 1-2-3: In the wake of his stunning defeat as the 1-9 favorite in the Wood Memorial, champion Uncle Mo underwent a battery of tests at Belmont on Tuesday. The results of the tests – which trainer Todd Pletcher said are completely routine for a horse in his barn that suffers a puzzling defeat – will be available Thursday. A press release from his connections said Uncle Mo was “completely sound.” The tests includes blood work, ultrasound of the internal organs, and stomach scoping.” The colt is expected back on the track tomorrow morning and will ship to Churchill Downs on Monday.

Dial tones: Florida Derby winner Dialed In breezed an easy half in :49.90 at Palm Meadows with regular exercise rider Maxine Correa up. Trainer Nick Zito says the son of Mineshaft will have one more five furlong work before the Kentucky Derby – a similar pattern to how he trained the colt up to the Florida Derby. Dialed In will remain at Palm Meadows until early May.

Factor in: Arkansas Derby favorite The Factor arrived at Oaklawn Tuesday morning after taking a Tex Sutton charter flight out of Southern California. The colt is returning to Oaklawn after winning last month’s Rebel by more than six lengths. Martin Garcia has the mount.

Challenger: Southwest winner Archarcharch breezed a half in :50.80 after the renovation break at Oaklawn, going in hand under regular rider Jon Court. The Oaklawn clocker timed the colt galloping out five furlongs in 1:03.80. Archarcharch was third to The Factor in the Rebel, and will try him again in the Arkansas Derby.
