The Federal Police, army and marine corps are providing security during the Mexican Open, which starts Monday in the Pacific resort city of Acapulco, organizers said.
The tournament is being held in Acapulco's upscale Punta Diamante section.
"We have support on the perimeter from all the levels of government, the navy, the army and Federal Police, performing constant patrols on the roads near the complex," the event's security chief, Manuel Vergara, said in a statement.
The tournament did not say how large the security deployment would be, but unofficial reports said more than 3,000 security forces members would protect the tennis complex.
Players and fans will be safe at the tournament site, with Guerrero state officials and Acapulco city officials working on the security arrangements, Vergara said.
The three levels of government "have always given us good results. No player has discussed the issue of security and that is a good message that we as organizers give them," tournament director Raul Zurutúza said.
Spanish tennis star Rafael Nadal, who is on the comeback trail after a seven-month hiatus due to an injury, is among the players who will be competing at the Mexican Open.
The security operation is designed to go from "inside the complex out," with strict controls on access and monitoring of the beach area, Vergara said.
The Mexican Open, a mid-level ATP Tour tournament, is played at the Mextenis complex in Punta Diamante.
A Belgian tourist was gunned down in Diamante over the weekend by several men who attempted to steal his luxury car.
The Belgian tourist was murdered nearly three weeks after six Spanish tourists were raped in the Punta Diamante section.
Several suspects have been arrested in connection with the rapes, which occurred on Feb. 4. EFE
