Roi du Monde squares off with Stay Tune once again, anchoring the wide-open Gran Premio Estrellas Juvenile

The Stud RDI homebred will attempt to replicate his dominant performance from the Gran Premio Gran Criterium (G1), where he turned back his rival by a length to secure top-level honors. The high-stakes rematch adds immense star power to the 36th edition of the Carreras de las Estrellas festival, which kicks off its two-day championship showcase this Friday at San Isidro

The Carreras de las Estrellas festival recaptures the spotlight of the Argentine racing world, illuminating the national turf with its hallmark showcase of pure equine excellence. The prestigious series traces its roots back to 1991, born from the visionary ambition of a pioneering group of breeders—including Juan Carlos Bagó, Hernán Ceriani Cernadas, Raúl F. María Lottero, Luis Villamil, Alejandro Menditeguy, and Ignacio Correas—who dreamed of bringing a Breeders' Cup-style championship event to South America.

This Friday afternoon, over the same expansive turf course at Hipódromo de San Isidro where the story first began, the Fundación Equina Argentina celebrates its 36th anniversary renewal. The historic event continues to command the same elite anticipation as its inaugural card, which saw future legends Gold Spring (Gold Trojan), Irina (Ringaro), and Intérprete (Farnesio) etch their names into the record books, paving the way for iconic multi-time champions like Wally (Southern Halo) and El Compinche (Southern Halo) to sport the series’ traditional orange saddle towels.

Now structured as a spectacular two-day racing festival, the opening day card places the spotlight squarely on the 2-year-old crop and the main-track features. The championship action will build toward Saturday’s blockbusters: the Classic (G1), Distaff (G1), Mile (G1), and Sprint (G1)—the first three of which boast enhanced global visibility as part of the international World Pool commingled betting network.

For Friday's opening leg, the Gran Premio Estrellas Juvenile (G1)—the traditional one-mile championship test for colts—takes center stage as a definitive divisional decider, barring a major upset.

Form analysts will naturally look to the Gran Premio Gran Criterium (G1) as the primary indicator for today’s contest, run under identical conditions over the course just over a month ago. That afternoon, the exceptionally gifted Roi du Monde (Treasure Beach) validated a flashy debut score by turning back Stay Tune (Fortify) to capture top-level honors. Armed with an explosive turn of foot, the Stud RDI homebred will likely appreciate a contested early pace to set up his deep closing kick. However, Stay Tune is unlikely to make things easy for the favorite; the Stud Las Monjitas colorbearer endured a troubled trip in the Criterium and looks poised to erase the one-length margin that separated the pair.

An alternative line of elite form arrives via Palermo’s Gran Premio Montevideo (G1), a race that saw Emotion Rate (Emotion Orpen) awarded the victory in the stewards' room following the disqualification of first-place finisher Colorado del Monte (Strategos) to third, with Paulo Sil (Treasure Beach) elevated to the runner-up spot.

Adding further depth to the Grade 1 lineup is Fletcher (Gershwin), who followed a dominant maiden special weight victory at Palermo by stepping up to capture La Plata's Clásico Pedro Goenaga (G2) in effortless fashion. Trainer Juan Saldivia holds a strong back-up hand with Barto (Pneumatic), an upwardly mobile colt who successfully graduated from the maiden ranks in his second lifetime appearance over this course, leaving the distinct impression that his stakes career is only just beginning.
