Braves’ prospect Sean Newcomb made his highly anticipated MLB debut Saturday in the first game of a doubleheader against the Mets. Although he took the loss, his performance was a HUGE victory for the Atlanta Braves.

Sean Newcomb looked like a veteran hurler when he took the mound for his Major League debut. He went 6 & 1/3 innings, allowed 4 hits, 1 run, 2 walks, and struck out 7 men for the Atlanta Braves. Whether he’s here to stay or not, his debut signifies the start of what Braves fans hope to be a superb career.

Here are 3 takeaways from the rookie’s impressive debut.

1. The rebuild is working.

Newcomb is one of very many talented arms the Atlanta Braves have in their system, and his immediate success is a sign that the guys that John Coppolella acquired were indeed, good for the team’s future. Other guys like Lucas Sims, Kolby Allard, and Mike Soroka are all seeing great success pitching in the minors, and could be ready soon.

2. Newk is ready to face MLB hitting.

It’s been a trending idea that Newcomb isn’t ready for the Majors due to his lack of control, but even with two walks, he was able to work around them, and miss the Mets’ bats quite frequently throughout quality start. Neither walk led to the lone run he surrendered. His ability to strike guys out frequently will be greatly appreciated in the hitter-friendly SunTrust Park.

3. Bartolo Colon may be on the way out the door.

Big Sweaty and his league-worst ERA have made the Atlanta Braves suffer long enough. After Saturday’s performance, there are very few reasons not to allow Sean Newcomb to continue pitching at the highest level, and that means someone’s gotta go. Once Bart’s all too convenient “DL stint” is over, I don’t see him even returning to Atlanta.

I’d hate to see Newk go back to AAA, but I’d bet money he’d be back within a month if he did. If he stays in the MLB from this point forward, then all is well, and more will follow. This is start of something positive for the Braves and thier fans for sure.
