Alonso, speaking Monday from spring training in Port St. Lucie, Florida, said he is fine and will participate in a full workout with the Mets on Tuesday.
"Yesterday I got in a really kinda brutal car accident. ... To me this is just really special to be here," Alonso said. "This is a really special spring training because yesterday was a really close experience to death."
"I'm thankful to be alive," Alonso added. "I'm really thankful that I'm healthy, very thankful to be here. Anything can happen at any given moment. I'm just really, really blessed to be here.
"One [moment] I was coming here to work, coming to spring training, and next thing I know I'm kicking my windshield in trying to get out of a flipped-over car. Just really blessed to be here. Thankful nothing is wrong. Also thank you Ford for having great engineering."
Alonso was the only person in the car when the accident occurred in his hometown of Tampa as he was heading to spring training. His wife posted video from the scene of the accident on Instagram.
According to Tampa police, the accident occurred around 6:30 p.m.. The other driver was issued a citation for running a red light, and the crash is under investigation.
The 27-year-old slugger is coming off a season in which he led the Mets in every major batting category: hits (147), home runs (37), RBIs (94), batting average (.262) and on-base percentage (.344).
