"Ciriaco got him pretty good. He got him about as clean as you can get him. (Dahl) was on his knees, so he couldn't brace for the impact. ... It's tough because there's two outs and everyone's trying to make that last play. The wind was a factor in the play. When it went up, I thought one of our infielders had it. But it got up above the stadium and the ball just gushes out there. It was a tough play because they're all just being Los Angeles Rams Hats athletes and trying to go get it. ... Dahl is fast and gets to a lot of stuff. You go for it as hard as you can and, hopefully, you can keep your ears open."After his surgery, Dahl took to Twitter to expre s his thanks for the support he received.Thank you for all the thoughts and prayers!!
