He was then entered in the October 20 Clasico Ricardo Ortiz de Zevallos, a 2000-metre (approximately 1¼ miles) Group One race that is the second leg of the Peruvian Quadruple Crown.
For the 2008 racing season, Tomcito was shipped north to the Palm Meadows Thoroughbred Training Center in Boynton Beach, Florida and has been nominated to the 2008 U.S.
Breaking from gate 4 of 12 in the $1 million Grade 1 Florida Derby at Gulfstream Park on March 29, 2008 at 1 1/8 miles distance Tomcito finished 3rd after closing from last place.
