Can't post a the link, but it was on ESPN and the Rangers website. After a second neck surgery, his career is over. It's a shame, but at 32 years old, and man of his size, he didn't have many years left anyway.
Interestingly, he ends his career with 319 career home runs, the exact same as his father Cecil.
One of my favorite players to watch long before he was a Ranger, especially in home run derby.
Hopefully the rest of his contract is insured.
