Former Met Rusty Staub suffered a heart attack on a flight back to New York from Ireland, according to source close to the situation. The Mets, who confirmed that Staub "experienced a medical emergency," said the former first baseman and rightfielder was diverted back to Ireland to get treatment.

"Rusty is now resting comfortably," the team said of the 71-year-old, six-time All Star. "The prognosis is good and Rusty and his family ask that we respect his privacy during this period. He is in the thoughts and prayers of the Mets organization."

Staub had two stints with the Mets -- one from 1972 to 1975, and another from 1981 to 1985 -- and, in 1975, broke the Mets record for RBIs in a season, with 105. Staub underwent a procedure in Ireland, according to the source, and should be back in the United States in a few days.

Staub, was at Citi Field during the previous homestand, just before the team left for its division-clinching series in Cincinnati.A man claiming to be a friend of Staub, Stephen Marro, has set up a GoFundMe page for Staub's flight back home on a medical plane, and is asking for $60,000.

"Rusty was traveling home from Ireland yesterday when he suffered heart attack midair," the website said. "Miraculously, there were two doctors on board the plane that sprung into action and were able to revive him. The "Miracle Met" was then transported back to Ireland where he underwent emergency surgery that was a success."

As of yesterday afternoon, Marro had raised over $3,500.
