I've been happy with Heyward since his comeback from the appendectomy. He's actually going to the opposite field for the first time in three years. He had a really good series in LA and got his avg to 200. Hopefully he keeps it going. I still think the true franchise player on the Braves is Freddie Freeman. He is the most consistent hitter they have and has been an RBI machine.
Also, it looks like Medlan is starting to find that groove that made him so good last year. I swear the Braves refuse to give him any run support to though.
