Joao Fonseca vs Thiago Monteiro prediction
Joao Fonseca’s stuttering start to the season continued in Buenos Aires last week as his title defence ended early with a three set defeat to Alejandro Tabilo. As a result, Fonseca moved outside of the top 35 in the world rankings. A back injury saw him pull out of two tournaments in early January and he was also defeated by Eliot Spizzirri in the first-round of the Australian Open. Fonseca will hope to pick up his first win of the season at his home event.
He takes on a fellow Brazilian in Thiago Monteiro. The 31-year-old is ranked outside of the top 200 but qualified for this event as he came from a set down to defeat Dusan Lajovic in the second stage. His best result of the season so far was a quarter-final appearance in Itajai on the Challenger Tour.
This is likely to be the match where Fonseca truly kickstarts his 2026 campaign, and he has more than enough quality to get the job done in straight sets.
