Maybe winning 63% of the one run games is not something the Braves can count on, but one run games aren't a coin flip either. Good teams tend to win them at higher rates, particularly those teams that have good pitching.
The Braves were 18-20 on May 9th. I think I remember that being a symptom of pitching dysfunction, but it might be interesting to go back and look. I think with the Braves lineup now you could expect a more stable pitching staff to pick up several games there. That's a hypothesis anyway.
That might well offset any reduction in one run games.
the Braves were swept in the opening series due to terrible pitching.
Soroka and Folty were out and i don't believe Fried was in the rotation yet.
SP being better from the start will be big for sure.
