Goals in each half from the 35-year-old gave Panama a 2-1 over Bolivia in the Copa American Centenario on Monday - a win hailed as ‘historic’ by Panamanians given they had never faced South American opponents in a competitive match before.
Certainly, judging by the reaction of Perez, who collapsed to the ground and was mobbed by his team-mates after striking the 87th minute winner, the victory was more than just a good start to their Group D campaign.
“We are enjoying this one,” Perez told reporters after the game, “It is our first time in the Copa and it is a joy”.
The brace took Perez’s career tally for his country to 41 goals in 106 appearances and will have surely ended any debate over whether coach Hernan Dario Gomez was right to stick with the forward despite his age.
“Blas works so hard, does so much running and he knows how to score,” Panama keeper Jaime Penedo told AFP after the game.
“He is also a great guy, a real leader in the dressing room,” he added.
Perez has seen his share of different dressing rooms having played for 16 clubs in eight countries.
After debuting in his homeland, he has performed in Uruguay, Mexico, Colombia, Spain, the United Arab Emirates, the United States and Canada where he currently plays for Vancouver Whitecaps.
“He is a man that represents a lot of things on and off the field. He has had his share of heaven and hell but again, he was out there demonstrating his qualities for 90 minutes, running and fighting,” said Gomez.
“He scored two very important goals tonight. This group loves him and he transmits a lot of important things to the group. We have supported him, even through his difficult times. He has great experience, he is a great man and Panama loves him”.
Panama has never reached a World Cup final and while the improving nation certainly has a chance for Russia 2018 that may come too late for Perez.
That will make the upcoming two games in Group C, against Argentina and Chile, even more special for the Panama City born forward.
“Argentina will be hard, Chile too,” said Perez, “But our coach just told us - now go and enjoy this Cup.”
Judging by the smile on his face, Perez needs no invitation.
