Ronaldo Vieira.

Ronaldo Vieira is a midfielder for the San Jose Earthquakes, wearing number 14 in Major League Soccer. Specific details on his height, weight, nationality, and background are not on file at this time, limiting a full biographical breakdown, but his role as a central midfielder places him at the core of the team's build-up and defensive structure in the middle of the park.

No current 2026 season statistics are available for Vieira at this time, so a stat-driven prop angle cannot be constructed from the available data. In general, midfielders in his positional role are relevant to bettors tracking shot attempts, key passes, and card markets, as box-to-box and defensive midfielders often accumulate fouls and disciplinary events at a notable rate. Once Vieira logs consistent minutes and statistical output for San Jose this season, prop markets around shots on target, passing volume, and anytime card props become worth monitoring. Bettors following the Earthquakes roster should watch for updated depth charts and lineup confirmations, as a midfielder's playing time and positional usage directly influence the value of any individual player props tied to his name.
