Veteran forward set for Orlando City, according to Kaka
There was no official announcement from Orlando City, who signed Italian midfielder Antonio Nocerino in the off-season, but Kaka confirmed Baptista's arrival via Twitter.
Ex-Arsenal, Real Madrid and Sevilla forward Baptista, 34, has been without a club since leaving Brazilian side Cruzeiro in December.
"Another life and career moment that we'll course together! Welcome @J_Baptista81 to @OrlandoCitySC #thebeast #labestia," Kaka wrote via his official account.
Baptista only made three league appearances for Cruzeiro last year but helped guide the club to back-to-back Serie A titles in 2013 and 2014, having arrived from Malaga.
Orlando City are third in the Eastern Conference with five points after three rounds, following Friday's 1-0 win at New York City.
