Knebel has a UCL tear. Not sure on the severity. Based on the fact he's getting a second opinion I'm guessing the first told him he needed Tommy John.....Luckily our bullpen is deep but I'd love to add another arm. Can never have enough bullpen arms IMO. Hell give Kimbrel the years. He's been about as good his entire career as anyone can ask. I think he'll still be pitching well at age 36.
