Although we are still awaiting official word of the final diagnosis, all signs point to Braves right-hander Kris Medlen undergoing his second career Tommy John surgery in the near future. He left Sunday's start holding his elbow and told reporters on Wednesday he is preparing to go under the knife.

Medlen, 28, had his first Tommy John procedure in August 2010 and did not return to a big league mound until very late in 2011. He has been brilliant since the first surgery, pitching to a 2.45 ERA (160 ERA+) with a 3.99 K/BB in 337 1/3 innings from 2011-13. With the new elbow ligament in place, Medlen had emerged as one of the best pitchers in the game.

"Tommy John now is almost like a root canal," said Braves manager Fredi Gonzalez to Jeff Passan of Yahoo! Sports last year, a pervasive view of the high success rate of elbow reconstruction. Depending on who you ask, 80 to 85 percent of pitchers who have Tommy John surgery come back just fine. Medlen happened to fall in the other 15 to 20 percent.
