"Following a thorough examination and assessment of Gary Carter, biopsies were performed this morning from a tumor located in Mr. Carter's brain," the statement read. "The preliminary results are that his tumor appears to be malignant. Once the pathology report is available, which will take several days, we will discuss treatment options with Mr. Carter and his family.
"In the meantime, Mr. Carter is in excellent spirits and good physical condition. He is resting comfortably, surrounded by his family. We hope that his friends and fans will continue to pray for Mr. Carter and his family during this time."
Carter, 57, revealed last weekend that doctors had found several small tumors on his brain, and that he would undergo further testing at Duke Medical Center.
"My wife, Sandy, and our children and family thank you for your thoughts and prayers," Carter said at the time, in a statement released by the Mets. "We ask that you please respect our privacy as we learn more about my medical condition."
Inducted into the National Baseball Hall of Fame in 2003, Carter played 19 seasons in the Majors with the Expos, Mets, Giants and Dodgers, batting .262 with 324 home runs and 1,225 RBIs.
"We know that he's a competitor, and I think that gives him an edge," said Mets first-base coach Mookie Wilson, Carter's teammate in New York for 4 1/2 seasons. "Knowing him, he's going to go in it with the intent of beating it. I think that's the only way for anyone to do it, and Gary, that's just the way he is."
An 11-time All-Star and three-time Gold Glove Award winner, Carter won a World Series ring with the Mets in 1986, when they beat the Red Sox in seven games. Carter delivered a two-out RBI single in the 10th inning of Game 6 to send the Mets to their improbable comeback victory, punctuated by Wilson's grounder between the legs of Red Sox first baseman Bill Buckner.
"Gary was one of the happiest guys in the world, every day," Wilson said. "I saw him a couple months ago, and this wasn't even an issue. He was in good health, good spirits. Then to find this out, it's shocking. We're pretty much the same age, and it could happen to any of us. We just have to hope for the best, that's all."
