1. Run differential. The Braves have outscored their opponents by 11 runs. This is rather surprising to me because of the lack of offense from the team so far, but it shows how great the pitching staff really has been. They are ranked second in the National League in FIP at 3.17 and second in fWAR at 4.1.
2. Dan Uggla will be fine. This much we know. He won't hit .182/.234/.398 with a 6.4 BB% and .269 wOBA all season. How much he improves as the season goes on is not known, but his career numbers indicate plenty of good things in the future, and age should be not be a factor this early in the contract.
3. Pitching. The Braves have six good starting pitchers, as Neyer points out. The rotation's strikeout-to-walk ratio is 3-1, and with two sinkerballers, that is a pretty big number. This is largely due to Derek Lowe's increased strikeout rate of 7.81 K/9 and the emergence of Brandon Beachy and his 9.51 K/9. Also, the staff's command has been excellent across the board.
