Astros outfielder J.D. Martinez told MLB.com on Friday that while he has yet to starting swinging a bat again, he feels he'll be ready when spring training rolls around. Martinez underwent surgery to remove the hook of the hamate bone in his left hand in September. "I really haven't been able to swing that much yet, but I feel like it's right there and really close," he said. "I'm trying to rest it as much as I can now because I know when spring training starts, it's going to be non-stop. I feel like I'll be ready and it will be strong enough for me to do what I have to do."
