Darryl Strawberry Suffers Heart Attack, Recovering At Hospital

Darryl Strawberry says he sustained a heart attack on Monday evening -- but, thankfully, medics were able to save his life ... and he's now recovering at a hospital.

The three-time World Series champion explained in a social media post the health scare happened in the St. Louis area.

He didn't go into too much detail about the emergency ... although he did say docs had to bring him "through a stent-procedure" to fix his ticker.

Fortunately, he added the process "brought my heart to total restoration!!!"

"Your prayers are so absolutely appreciated as I continue to recover," he wrote on his Instagram page, "in Jesus Name! #savedbyHisgrace❤️❤️."

Several celebs commented on the post, including Alex Rodriguez, Matt Barnes and Cecil Fielder, showing the ex-baseball star love and gratitude that he's now doing OK.

Straw's got a big few weeks coming up ... Tuesday is actually his 62nd birthday -- and on June 1, he's slated to have his No. 18 retired by the New York Mets.
