Matias Soto enters as the clear trader consensus favorite over Mariano Kestelboim in this ATP Challenger Santa Cruz de la Sierra round-of-32 clay-court clash, reflecting his higher ATP ranking of 304 versus Kestelboim's 622, along with stronger recent Challenger experience. Soto reached the second round in Mexico City last week, defeating Jay Clarke before falling to Stefano Napolitano, while Kestelboim holds a 1-4 singles record in 2026, including a retirement in Campinas qualifying. Both South American clay specialists share no head-to-head history, but Soto's form and ranking suggest an edge on the outdoor Bolivian courts, though upsets remain possible in early rounds with no reported injuries or withdrawals.
