The 6-10 free agent - clad in the same navy blue Yankees hat he wore to the Broadway show "Rock of Ages" on Saturday night - arrived at the corner of Jerome Avenue and 161st Street in a black tinted Escalade about 20 minutes before the first pitch. He left the game after the fourth inning.
Souvenir stand attendant Gerald Ramos shouted "Let's go, Knicks!" as Stoudemire emerged from the SUV before the game, flanked by two young women and a man. Stoudemire's agent, Happy Walters, was also part of the group. The power forward, who received tickets to the game from Yankees reliever and pal Joba Chamberlain, entered the Stadium's suite entrance.
"I'm excited," Stoudemire said about attending the game. "It's my first time. It's going to be a lot of fun."
Stoudemire was quite talkative about his possible future with the Knicks as he waited for his limo to pick him up from the Broadway show Saturday night.
"I've talked to Carmelo Anthony that he needs to come out here," he told reporters. "I've talked to Tony Parker. Both guys are ready to join me if I decide to come here. So we will see if we can work it out."
But Sunday, Stoudemire - who will meet with the Knicks on Monday - was far less talkative before the game. When asked what it would take to bring Anthony and Parker to the Garden, Stoudemire replied, "It would take some thought process," before quickly darting into the VIP Legends Suite Club.
Newsday, however, caught up with Stoudemire and his entourage as they exited the ballpark. Before he climbed back into his Escalade SUV, Stoudemire said his meeting Sunday with Knicks coach Mike D'Antoni, his former coach in Phoenix, "went great."
"It's possible I'll be reunited with him. It's possible," he said. "But lunch was great. We had great conversation."
He also said his surgically repaired left knee is not an issue.
"I feel great. Totally healthy," said Stoudemire, who missed almost all of the 2005-06 season following microfracture surgery.
Ramos, who has sold souvenirs at the new and old Stadium for most of his adult life, said he's seen countless celebrities, such as Jay-Z, Beyoncé and Rachel Robinson, enter the Stadium from his sidewalk post.
"Let him come to the Knicks, please," said the 57-year-old, who lives around the corner from the Stadium. "I think the Knicks should get him. They have as good a shot as anybody else. I like him, I like him."
